Hey there fun going fast, so my yfz 450r has a full hmf exhaust system hooked up on it along with a dyno jet power commander fc, it’s giving me a lot of issues, if I buy the FMF full system exhaust, would i still need a fuel controller ?
Hey man. Yeah all the manufacturers recommend a fuel tuner with a full exhaust so it doesn’t run too lean. Sorry your set up isn’t cooperating. Ive heard good things on the Dynojet. I did a quick search on the Dynojet website and they have preset maps for the full GYYR, Two Brothers, and Yoshi exhausts if you wanted to look at one of those set ups. I never could get my HMF slip on w tuner running right in the first part of the throttle. Ironically I had a YFZ 450x with a Big Gun slip on, no tuner, and had no issues wtih it at all. Go figure. Best of luck.
Cool! I ride a 2004 and love it.
Nice! Thanks.🙏

@@FunGoingFast what about FMF, I was looking at the FMF full exhaust system, but I don’t see no power commander with the pre mapped tunes
@@FunGoingFast I might get the yoshimura, can you send me the link that shows thr preset tune for the exhaust ?
Hi, I have an 04 yfz 450 and I wanted to know if I get an 07 yfz clutch case with the oil squirter would it fit?
Im not sure. If you google yfz 450 oil mod, there are a bunch of articles on how that works. But i thinks its basically what you are planning.
