Question for SPORTSMAN70003 and Dirtbmw20!!!!

[Rubberdown]

Looking at those chrome stacks you guys got, what did you do, just mount those solid to the front rack and run some flex hose up the inside of them for your actual snorkel tubes?

[SPORTSMAN70003]

I have them mounted solid thru the rack and also the inside 2 bolts is thru the rack support. I then took ferncos and connected the snorkel hose to the stacks.
If your not familiar with what a fernco is you can see them here. http://www.fernco.com/coupling.asp


Its hard to see but in the picture below you can see my snorkel tube the then you can see a clamp on the fernco and I have the fernco slide over the stainless pipe. In this picture I didn't have the top clamp on. I'll try to take some close up pictures of how mines done.

[Rubberdown]

Ohhhh... I see, the chrome tube goes through the mounting plate a little bit so you can connect them with what I would call a rubber coupler or connector. Did you weld the chrome pipe to the mounting plate from the bottom, and how did it weld being chrome?

[Dirtbmw20]

I did mine a little different. I made a metal plate that I milled four holes in for the stacks to slide into. Once I slid the chrome stacks into the plate, I let them stick out the bottom about an inch or two so I could get my spa hose attached to them. I then welded the stacks to the bottom of the plate so they would be real sturdy. I then integrated the metal plate to fit inside my relocate radiator bracket so all I have to do is bolt the metal plate down with the radiator bracket, that way if I wanted to take the chrome snorkels off, all I have to do is loosen the four bolts to the radiator bracket and take the metal plate with the chrome stacks off the bike. Here are some pics, you should be able to figure out what I did by the pics.

[Rubberdown]

Looks good buddy, now I undestand. Id the 4th one just for show, or did you just not have it hooked up to the hose yet?

Also, whats with the little tabs in the end of the snorkle tubes?

[Dirtbmw20]

The 4th one is for the belt exhaust, it just wasn't hooked up yet in the picture. The little tabs in the pipe are for the mounting plates to mount the bed rails on a truck, I just left them there in case she ever shredded a belt, the belt fragments wouldn't slap her in the face plus I didn't want to risk messing up the chrome plating by trying to cut them out.

[SPORTSMAN70003]

Yeah mines done exactly like dirts except I have 2 metal plates.

[Dirtbmw20]

Cool, I didn't really read well enough to realize you used the metal plate too, so maybe they aren't that differently mounted. Using the metal plate REALLY stiffened the mount up for the stacks. Hell..... she can take down small trees with her stacks they are mounted so good.

[Rubberdown]

I was looking up the rails on line, the cheapest I could find was like $110, man, I didnt really wanna spend that much coin just for new stacks :(

[SPORTSMAN70003]

I give $41 for my rails off ebay shipped to the door. They were like brand new. Just look on ebay for the cheapest set.

[Dirtbmw20]

I was looking up the rails on line, the cheapest I could find was like $110, man, I didnt really wanna spend that much coin just for new stacks :(

Paul, yep, if you buy them brand new that is about what they cost. With me being in the automotive parts business, we have them things laying all over the place so I got them for free. You can find them pretty cheap if you look in some of your local car/truck trader magazines, people will buy used trucks and not everyone likes them so alot of people will take them off and sell them for dirt cheap or even some car dealerships will take them off traded in trucks that might be slightly damaged (dents, dings, scrapes, scratches, etc.). Pick up the phone book and call some of your local dealerships, sometimes they'll even GIVE them away just so they won't have to mess with them.

[Dirtbmw20]

Ebay item# 140144342762

Ebay item# 150148564351

Those are two of the cheapest, there are tons more out there.

[Rubberdown]

thanks bro, I think I'll buy a set from one of those auctions. I just have to wait on shipping for the one item and the diameter of both of them.

[KSCFIRE]

Ok I'm confused, please be patient I'm new to this mod stuff. Why 4 stacks, ones for belt intake, ones for belt exhaust and ones for the carb intake?What's the fourth for? Remember be kind.

[bmdjmd]

dual intake snorkels, it aids in tuning the machine as i understand it.

[Turk]

Do the belt housing hoses,1 for air intake and 1 for venting hot air out Do they both go into 1 snorkel?

[Rubberdown]

2 of them for the air box, since the snorkle is sooooo much longer than the factory air box snorkle, you require 2 of them for the proper air flow, and even then sometimes re-jetting the carb is still needed.

[Dirtbmw20]

Do the belt housing hoses,1 for air intake and 1 for venting hot air out Do they both go into 1 snorkel?


Turk, NO, they have to be different hoses in order for it to cool properly. It doesn't do any good to continuely re-circulate hot air back into the clutch housing, you would toast the clutch in no time like that. You would have warped and cracked sheaves over time and it probally wouldn't take long with all the hot air having no way to escape and re-circulated back through it.

[Turk]

Thats what I thought.So it's 1 snokel for each hose.Thanks for clearing that up.

[Dirtbmw20]

Yes, that is correct. One snorkel per each hose.

[KSCFIRE]

2 of them for the air box, since the snorkle is sooooo much longer than the factory air box snorkle, you require 2 of them for the proper air flow, and even then sometimes re-jetting the carb is still needed.

I guess there is a Y or a T involved for the dual intake set-up?
P.S. More questions in the future about this snorkling stuff I'm going to do mine after a trip I have planned for WV in Oct. Don't feel like chasing jetting and fab work before that.

[Rubberdown]

KSCFIRE a lot of guys will make a new plate for the top of their air box lid with 2 hose fittings on them, they remove the factory one that is just black plastic and I think its riveted on, then put the new top in its -place and silicone it and screw it together. I'll try to find a pic of it...

[Dirtbmw20]

KSCFIRE, there are usually two seperate fittings run. If pulling off a Y or T then you're ultimately only pulling through one 1 1/2" opening which defeats the purpose of having dual inlets. On BOTH my bikes that are snorkeled, two complete seperate fittings are coming off the air box, no Y's or T's coming off my air boxes.

[KSCFIRE]

Got ya, I just happen to have an extra 800 air box snorkel. So if I use it to I might be ok? Thanks

[crsbear400]

I think I gave around $60 bucks for new bed rails at Auto Zone. I'm hurt that you didn't ask the original chrome stack guy concerning this topic. Even though you didn't ask, I will add that I did mine with some 1.5" exhaust header flanges. Slid the pipe inside and welded them around leaving enough pipe below the flange to attach the fernco or rubber coupler.

[Rubberdown]

Buddy, I'm sorry I didnt ask you first, I KNOW you are the original CHROME STACK MASTER but I also know you dont like people copying your great ideas so I was trying to sneak them onto my machine under the radar without you knowing until they were done, then I was going to see if you approved of my job ;)

[crsbear400]

RD, i don't mind people using my snorkel setup, just don't leave me out of the discussion(LOL)! It's flattering actually. I should have added a smiley to my previous post to better punctuate the mood of my post. I think your bike will look much improved with the chromies on there!! I say go for it!! Post pics of your progress.

[Rubberdown]

I'm soooo excited, I got my stacks in today :D :D :D

I was thinking 1/4" plate to have them welded to, that should be thick enough eh guys?

I got 1 week to get this done and the rad relocated and tested out and I still have to find some better hose for the snork's, all I have now is that sump pump stuff, but it has worked so far, I'm just worried it will get too hot and have a melt down if I'm riding ALL day for about 6 hours.....

[crimbshaw188]

yeah dual intake means more air to work with when tuning and

[Dirtbmw20]

I think 1/4" steel plate is gonna be heavy as hell !!! I know you don't have the storage box on front like ours do but on the wife's bike, I used 3/16" plate (I didn't want to use that thick but it was free) and between the weight of the radiator & bracket, the metal stacks, and the steel plate, while riding the top of the box will come unlatched and just about shake the hell off the bike if you're not watching. It is so heavy that the two latches come un-done so easily because it's like someone is pushing down on the top lid. I know you don't have the front box to worry about, just thought I would tell you that anyways. I would look at using something more along 1/8" and when I re-do mine here shortly that's what I'm using on mine is 1/8" plate.

[04.5700EFI]

Dirtbmw20 I LOOK AT THE PICS OF YOUR BIKE WITH THE RD 3" LIFT AND YOUR A ARMS OR NO WHERE NEAR THE ANGLE OF MINE...NOW I DO HAVE THE HL HD FRONT SPRINGS...BUT MAN IAM ON A SERIOUS ANGLE..I SCARED I WILL BREAK THE NEW GORILLA AXLES I JUST GOT.!! THEY LOOK LIKE THIS / \ I MEAN NOT THAT BAD BUT DAM CLOSE.!!

[Rubberdown]

LOL @ 04.5700EFI :D

Hey Lee, its not that heavy, I used some "free" plate as well and I think its around 3/16" to 1/4" thick. Its not that heavy, but I also dont have it on the lid of a factory box. I'm putting it all on tonight, I'll post some pics of the project from the beginning when I'm done.

As for the Rad relocation, I will consider starting it tomorrow, but if I think for a second I wont have it done in time, I wont bother.

[04.5700EFI]

Thanks For The Help Rd I Glad I Got This Lift Frome U ! !!! Lol !!!

[Dirtbmw20]

Are you 100% positive the strut plug is all the way to the bottom ??? AND the strut itself is set all the way down on the plug ??? Got any way to take pics ??

[04.5700EFI]

thanks for the help "dirtbmw20"..yeah its all the way down i made sure. could it just be the hl hd springs.. dont the spring along give u like 1" to 1 3/4" more lift..if so do you think that would be to much lift for the gorills??

[Dirtbmw20]

I'm not sure about how much lift he HL springs will give you. I don't know if you could go with a total of 4 inches on Gorilla axles or not, heck, all you can do is try, especially if they still have warranty on them. Everyone told me that I couldn't go 3" total with stock axles but I said to hell with them, I don't listen well anyways, they've been working great so far. You could always call Gorilla and ask them if you could go 4" on their axles, they'de be able to tell ya.

[04.5700EFI]

thanks again dirtbmw20.! i will call them.i was also thinking about cutting my bottom a arms and extending them about 1/2 to 3/4 of an " to get the tires more level.they toe out bad or toe in what ever u call it. :noidea:

[04.5700EFI]

How U Post A Pic????????

[Dirtbmw20]

I host my pics through photobucket and just copy and paste the IMG code.

[Rubberdown]

you can either post it from your hard drive where it says "managa attachments" in the reply page, or you can post the larger files from something like a photobucket account with the [img][img] tags in front and at the end of the picture url.

[PoPoRZR]

Load it on photo bucket or wherever...Then just reply..and there is a button called insert image..(which looks like a mountain) ....Then post the http:// address in the box that pops up and click ok.. then sumbit reply.. Not the best talk but i described as best as i could :hat:

[Dirtbmw20]

you can either post it from your hard drive where it says "managa attachments" in the reply page

Cool, didn't know that. I'm gonna play with that and see how that works.

[Dirtbmw20]

test

[Dirtbmw20]

Cool, it worked and you can click on it to make it big.

Paul, that is EXACTLY what I used for the belt exhaust on both my bikes, never had a single problem. I noticed you just have the spa hose stuffed down into a coupling with some silicone. Try the set-up above and it's guaranteed not to leak. They are assembled on the belt cover in the exact order you see them in the pic, then the spa hose slides onto the barbbed connector.

[04.5700EFI]

I Trying To Post Pic With Manage Att.it Shows It In The Att Files Part, But Will No Post

[04.5700EFI]

Oh Sh^t I Got It!

[04.5700EFI]

One More

[04.5700EFI]

See How Bad The Tires Lean Out !

[Dirtbmw20]

That's definitely a steep angle on that cv. I posted some pics of mine under the Thermoplastic Boot thread and they ain't near that bad of an angle. I see your tires poked out but it don't look ALL that bad although my bike doesn't do that. Are those 29.5's on there ??? I also remember something about the 2004 having shorter axles than the 2004.5. You don't think Gorilla sent you the wrong axles do ya ??? What year is your bike, is it a 2004 or a 2004.5 ???

[Rubberdown]

Okay Lee, so you have on the belt exhaust a rubber coupler thingy, then a barb, then the spa hose goes over top of the barb, is that correct. And is it a doble ended barb that gets hose clamped into the rubber connector, and then you silicon and hose clamp the spa hose onto the barb?

[Dirtbmw20]

http://i66.photobucket.com/albums/h260/Dirtbmw20/ExpandedViewOfBeltExhaustSnorkel.jpg

Here is a pic of the above pieces put together and installed on the clutch housing.

[Dirtbmw20]

The barbbed fitting is threaded on one end and it screws into the 45* pvc, the pvc fitting goes into the rubber coupling which goes into the STOCK OE rubber coupling off the clutch housing. Any of that make sense ????

[04.5700EFI]

Yes 29.5 Laws..04.5700 Efi And The Gorillas Axles Were About 1/2" To 3/4" Longer Then The Stock Ones..iam Lost Why It So Bad..the Only Thing I Can Think Of Is The Dam Hd Front Springs..but The Reason I Got Those Was Because The Factory Ones Sagged So Bad.real Bad

[Dirtbmw20]

The only EASY and cost effecient way I can think of to figure out what it might be is to cjange the front springs back to stock and see if it changes it. I saw where breeselawngarden on ebay was selling front springs for $50.00 for the pair a few weeks back, that is IF you gotta buy new springs but I would put the stocks ones back on it and see what it does.

[Rubberdown]

I dont have the stock fitting anymore, the bayou guys tossed it when they -put on my first set of snork's. I'll print out a picture of the parts and how you have them assembled and take it to the homedepot tomorrow. Did you use something similar on the intake for the clutch?

[Dirtbmw20]

On the clutch intake I just used a 1 1/2" X 1 1/2" rubber coupling with the same pvc set-up shown above coming out of it, the same barbbed connector so the hose just slides on. I don't have one single drop of silicone on MY bike, now I did use some on the wife's bike on the chrome stacks but on MY bike there is not one ounce of silicone used and I have NEVER had a leak on my bike.

[Dirtbmw20]

I'll post pics of the clutch intake when I get home this evening, the pics are on my computer and not on photobucket so I can't do it while I'm at work.

[Rubberdown]

cool, thanks

["Bankrupt"]

the axles and a arms on the 05 and up bikes are longer than the ones on the older sportsmans.

and 04.5, your springs arent sitting down in RD's lift. thats adding about 1/2-5/8 more. on top of your 3" spacers and HD springs. i can see the right side (looking at the picture) is not sitting down in the lift spacer.

and if you got new gorilla axles, i would run it till it breaks (which i dont think it will) ive seen gorilla axles at a shit load more angle than what yours are and they never broke.

[Rubberdown]

it would be 1/4" more in hhight if it was sitting on top of the cup, the cup is only 1/4" deep, just enough to keep the spring from moving around....

["Bankrupt"]

ahh. :lol:

well either way, its still not good to have it moving around like that

[Dirtbmw20]

cool, thanks

Here ys go Paul, this is the ONLY pic I have of the clutch intake. The rubber coupling I used is a 1 1/2" X 1 1/2". I got more pvc fittings in the garage, I can probally put the pvc fitting together and take some pics if you need me to. See if you can make this out...
http://i66.photobucket.com/albums/h260/Dirtbmw20/ClutchIntakeSnorkel.jpg

[Dirtbmw20]

Paul, Here are two pics of the pvc fittings so maybe you can understand what they are. I don't have any more of the threaded barbbed fittings that screw into the pvc fitting to take a pic of.


The first pic is of the 1 1/2" pvc pipe and the threaded adapter that goes into it. The adapter is glued in to the flanged side of the pvc pipe exactly as it is shown in the pic.
http://i66.photobucket.com/albums/h260/Dirtbmw20/PoPoPics008.jpg

Pic #2 is showing it put together, now the threaded barbbed fitting will screw into the end of the pvc fitting allowing you to just slide your 1 1/2" spa hose onto the barbbed fitting, once it's on that fitting, it has to be cut to get the spa hose off, it will NOT leak. The other half of the pvc fitting is slid into the 1 1/2" rubber coupling attached to the clutch intake opening.
http://i66.photobucket.com/albums/h260/Dirtbmw20/PoPoPics010.jpg


And when installed on the bike, it will look like this..............

Do U Have Any Pic. Of The Air Box Setup??? And Can U Only Run "1" 1 1/2 Line To The Air Box And Work??? Because I Can See How U Guy Got That Stuff To Fit Under The Seat And Then Under The Air Box There Is No Room.! Pics Please

[Rubberdown]

Thanks Lee, much appreciated buddy ;)

I have TWO fittings coming from my air box. On the 500's you HAVE to have two fittings.

How Are U Locking The 90 Down To The Plate?? I Know The Square Plastic Peace Is Bolted Down.but The 90 ?????

[Dirtbmw20]

The Square plastic piece is a piece of plexi-glass and it is bolted down AND bonded down to the lid with this industrial epoxy that we use at work, then I drilled a hole in the plexi-glass big enough for the fitting and I used the same expoy to bond it to the plexi-glass lid. You can see the yellow stuff around the edge of it, that same stuff is also CAKED heavily on the bottom side.

[04.5700EFI]

Thanks Dirtbmw20 You Been More Then Helpfull...i Think I Have It Now !?!

["Bankrupt"]

i ran both of mine out the bottom. you should run 2 on all bikes. you wont choke it down if you do. i only ran 1 on my 03 700 and it killed the bike. it wouldnt outrun a 90cc bike when i first did it.
