Post your pipe/jetting/air filter info please..

10 posts in this topic

I'm looking to get a new exhaust , then rejet and replace the stock airfilter.

I'm running a 2000 WR400F in full supermoto trim. I need it to run great all around. Right now it's running like [@#$%&!] with the stock pipe unplugged. The jets are all fubared and the stock filter seems to be choking it up.

Looking for information on your pipes. What's good, what's bad about whatever you're running. Then maybe list your jetting setup and what air filter you run.

Thanks,

Everett

I tried to search, was useless.

Look at my sig., this is the jets and needle I am running. I am not sure if you carb. is the same as my 426. My pipe is also not a straight through pipe, so, you will probably get a little more power with your pipe To accommodate that, try increasing my main by 1. You may or may not need to do that. Also, moving the needle 1 notch higher, 1 clip lower may give you a little better hit, but, on my bike it starts to introduce the "dredded bog" before taking off. The way I have my bike jetted now, it really runs good. Good luck with it. PS. I really like the EKP needle.
