Default FMF Gnarly vs stock Pipe?

     

I just got a FMF Gnarly for my 02 CR250, will this pipe make my jetting richer or leaner? thanks all!!

Don't forget to read the fine print:

Quote:
FMF jetting recommendations are based on the following conditions: Premium grade pump gas with Silkolene premix, 32:1 ratio. Sea level to 2000 feet above sea level. Temperature of 70 degrees Fahrenheit with average humidity.
If your premix ratio is different, you live at elevation, and/or your premium grade pump fuel isn't the same as theirs your jetting will vary.

For me their specs are way off, even when my bike was stock. Then again my specs don't match their fine print.

Ive got the Fatty and Shorty on my 02 and never messed with the jetting. It runs great. I meet their criteria though.

One of the few that cannot complain. This bike is hard to set-up anywhere but sea level.

Hmm, havent had any jetting issues. When I asked about jetting awhile back, I just thought there might be something Im missing. But after riding my bike, it really doesnt call me to mess with it. It BARKS!

You shouldnt have to change much of your jetting if you only have a pipe, but once you get a set of Reeds you might want to change the main. "Go V-Force 2 Reeds" But if you just have the pipe you should be fine with stock jetting.

fastest 250 I have ever ridden, and suspension is a dream!!!!

first Honda was a kawi boy but if they keep it up will ride nothing else.
