[quote="Racer92":1r5sj7mb]The new FMF Gnarly pipe I have for my RM250 doesnt fit worth a darn. Can you send these things back and have them jam it in a jig and refit it?[/quote:1r5sj7mb]
I have a new Gnarly on my KX250 and it fit great. Maybe you should buy a Kaw! 8)

Kawi makes a great bike for sure. But I love my '05 RM250 too much.

Racer92 are you a wood's rider? I am, and that's why I switched from a FMF Fatty to a Gnarly. The Gnarly is a better pipe in the wood's(More mid-range for those looooong steep hill's), However on a track it dosen't have the hit that the Fatty had! Why did you go for the Gnarly?

I've never had good luck with FMF exhausts. Dating way back to the early 90's. I don't use them. And I still see friends that have issues with their exhausts. No thanks.

FMF's FITMENT SUCKS

the knarly is made of thicker metal... which "tweaks" quite a bit in the jigs while welding from heat and cool down. I had this problem awhile back when I was making thicker gauge stampings.

It's the price you pay for having a heavy duty pipe. I'm sure they'll make right.

Yeah, that is what I was thinking too. Its not a huge difference, but the kick-start wont fold all the way back and I dont want it riding up against the pipe wearing a hole, plus in woods racing it could possible catch a briar, vine or something and snatch the lever out. The whole thing needs to 'tuck' in towards the carb closer.

I called FMF, very nice guy I talked to, and he said to call him back with the number stamped on it to ensure I indeed have the correct pipe to start with, and then if its correct, he would put it in the jig and make it right or gimme a new one. No hint of hesitation on making it right,,,,, kudos to FMF on that point.

I had a great experience with FMF as well. I bought a new ti4.1. It fit perfectly on my 06 yz450 and now perfectly on my 08 yz450. The problem I had was the 2nd ride with it I got hit and ran over on a start and essentially crushed it. I sent it to FMF and they fixed to where I thought they just sent me a brand new one for 50 buck including shipping.

I call them and thanked them and did a BBB review on how they "took care of the customer". Great pipe, great guys/gals, great company. Thanks again FMF!!!

I've had a fatty on a '99 YZ250 forever and I put one on an '07 KTM300XC. No fit issue.

Okay, I [i:3kaici55]finally[/i:3kaici55] got my pipe back from FMF. And it doesnt fit any different than it did when I sent it. The kickstart wont fold all the way in like it does with the OEM pipe and its rubbing against metal. Am I missing something?

Did you try adjusting your kick starter on the shaft? Moving it foward could be the fix.

just move the kickstarter back a notch or two ont he shaft and youll be fine.

The stock exhaust is the best. 9 times out of 10, an aftermarket exhaust won't fit as well as the stock stuff.

I had a RM 125 than had an FMF fatty on it when I crashed in the first turn I some how hit a guy in the broke rotor right in lower front of the head pipe(Big dent) . it really brought out some bottom end.

Just do stock pipe + PC shorty + vforce reeds, best of all worlds.


Manufacturing those has to be pretty challenging, keeping that many pipes in a pretty tight tolerance with all the weird shapes have to be a pain. I wonder how they form and build them.

Tried that, wont work. I wonder if anyone else with an '05 with the Gnarly has this issue.

With as many pipes as they make, and as long as theyve been doing this, youd think they could make a pipe that has clearance at contact points. This really isnt rocket science.

I wonder if Pro Circuit has the same problems.
