Pipe?

[The Flyin Hawaiian]

Ive wondered how a pipe designed specifically for the KX500AF would work over one that is converted from a CR500. I wonder if a smaller pipe co. such as Bills etc. would be willing to build a KXAF pipe. Ofcourse someone will have to donate their bike for a while to do so.

Forget Bill's. A buddy wanted a CR pipe from them since FMF don't make a Fatty for the Cr500's anymore. I personally watched him call at least a dozen times to Bill's. He said he was calling 3-4 times a day for awhile. Noone answers, it's voicemail boxes that are unavailable. He talked to Bill himself, early on, and he is a One-man-band, but said he would make one. That was 2 months ago. I think he is busy with 4 strokes and quads or something like that.

So i bought one of those Noleen pipes that have been on ebay for years.  $125 "works finish" just got it yesterday and it looks great!  I think I have a good collection now to modify one to fit.
This is what I have
2 stock kx500 pipes
1 CR500 pro circut
1 CR500 FMF gnarly
1 Kx500 FMF fatty
1 Kx500 Noleen
                        I hope with all of these I can come up with a pipe for this.  Mabey Jfab would want to do one for me?

So is there a good way or a specific mod someone could lead me to. Trying to give an updated look to my 97 500 pipe with no frame mods or anything like that

If someone on here with one of the AF K5's lives somewhere near Blalock TX I know for fact that If John from Jemco had a bike to use as a jig or a pipe to copy he will make you anything you want. He does lots of custom work. Now the pipe will be bare metal but he does great work and you can paint it or get it jet coated. check it out at jemcoexhaust.com. CBX

i think its a bit rough that you pay x amount of hard earned cash for a kxaf and get palmed off with a pipe designed for a cr5.the different bore and stroke equates to needing a different size dwell section at least.i know the af's arent a huge production run but if a jobs worth doing, its worth doing properly.

I have been kicking around the idea of marketing a better pipe but the 8K stampings cost for a pipe just is hard to bite on. A hand cone pipe just don't last long with the header route of the dirt bike.

Hopefully someone will come up with a different AF pipe.  My project starts this week.  Probably be a month or more before I get to the pipe.  Which hopefully will be the last piece of the puzzle for the project.

So with all of the pipes that I have I started with the noleen.  I cut it in 2 places......test fit it and gave up. Then I took the FMF CR5 pipe and it fit so so but would take more cutting. Next was a CR5 PC pipe and it fit nice execpt for the water ports on the side of the cylinder. With some heat and a hammer I made it fit! Of courseI had to also cut off and weld an inlet from the KX5 on to it though. Check it out.  everything is just tack welded so far.

doesnt look like a bad fit,is it a 'works' pipe?

[ZETTNORCAL]

Yes it is the "works" pipe

[kwakman]

let me know how it feels on top end as they are a 'rev' pipe and im thinking of getting one for the b2.thanx.

[Jon Jon]

Is the works pipe the way to go for the AF conversions as well? Namely the kxf250 frame? Anyone have a good donor kx500 pipe for sale? I have a Pro-Circuit on my 500 and I am not too interested in cutting it.

[bruuuuup]

I have just ordered a kx500af pipe from service honda, guess they started selling them now.

[squeak]

if you dont mind telling us, how much did it cost you?
