Are you guys cutting and welding the Kawi inlet on the CR500 pipe?
-
Yes, that's how Service Honda did it on my bike.

Thanks that's what I figured. I just didn't want to cut up a good kawi pipe. But I guess that's the only way.
-
Yup, I am in the same boat as you !

JFab could make your k5 pipe work from what i understand, and it would possibly be a better fit...
-
Call FMF and ask if you could buy the inlet from them for the KX500. Save that stock pipe.

So I called FMF and they said NO WAY on selling me just the inlet or a pipe. Said they have a contract w/Service Honda and that they are not allowed to. Guess I cut the stock pipe unless somone has a dented up one to trade.

I have a stock pipe in great shape if you wanna swap something close in value for it that'll fit my 01 K5.
-
Do you just need the part of the pipe with the O-ring grooves?

Who needs FMF, we have Larry! :-D

Larry,
They need about the first 2 inches of the pipe. If you were to turn a part, make it pipe dia. past the "O" ring grooves. SH uses about 4 inches if memory serves. I can look at one of there pipes tomorrow and even post a pic. Make many! :-D

No I acually have a really nice stock pipe. Just thought that I would trade my nice one to someone who had a bad one.
Trade down? I guess

Exactly That would be REAL cool!

From my Service Honda 2008 KX500AF, KXF450 chassis.
In the second picture, right of the end of the tape you can see where
they cut off a Honda mount or had to beat in the pipe for clearance
and then welded.

Hi guys does anyone know if pro circuit has made a pipe for the kx500af?
Im pretty sure the fmf pipe for the service honda kx500af has been done by fmf to fit, but i cant seem to find a pro circuit one.
I have seen a video of ryan capes doing a record jump on a kx500af and it looks like that might have a works pro circuit pipe on it.
If i cant find one i think i will just make one from a cr500 to fit in my kx250 frame. I just didnt want to have to dent it to get it around the motor. :|
On a side note has anyone notice much loss of power from the cr500 pipe with the dent?
I know when i stacked my bike and dented the pipe it ran alot worse, but that was a big dent.
-
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?
-
Yes it is the "works" pipe
-
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.
-
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.
-
I have just ordered a kx500af pipe from service honda, guess they started selling them now.
-
if you dont mind telling us, how much did it cost you?
-
The pipe was $220 plus shipping which they own you on but I needed it.
-
I've been ordering parts (and a bike) from Service Honda for years. They have never gouged me. A 2 stroke pipe is an odd duck to be shipping. There are associated costs to that. I paid 220 for my stock FMF Gnarly 5 years ago.
-
$220,- for a exhaust that fits almost right on sounds cheap to me!
In Holland the prices are a lot higher. Mine CR pipe costed $464, and cut it in 3 pieces to make it fit.

glad I don't live there

Hello from Greece. Can you please tell me whats the diffirent between Gnarly and Fatty? Which one is better for kxaf the FMF or ProCircuit? I am thinking of buying a pipe for my conversion from SH. Also the modify on the pipe is that they extending the inlet on the O ring only? How many centimeters? Soon i will start a new topic on this area with my project, Thanks in advance
