I have a 350 warrior and i just put a white bros. e-series pipe on it. I have not re jetted it and when i ride it and go to punch the throttle it boggs down tell it dies. Do i need to re jet it or just clean the old jets out and if so how?

 

When you let more air out the exhaust, it lets more air into the carb. That changes your mixture from the ideal ratio.........which was the whole point of getting the aftermarket exhaust in the first place! If you don't have to rejet, all you did was waste your money on a pipe that is louder (I know how loud those WB pipes are!), so you can upset your neighbors and get ATV's banned from more areas.

You are most likely now running LEAN, which is dangerous for your engine! Get it rejetted by an experienced professional. Consider running a quiet core as well.

 

thanks ill try that and get back too you

 

I agree.

 

Once again, yes, you have to re-jet. Expecially if its bogging at full throttle. If you want to get the most out of your pipe, also put in a less restrictive air filter and open up the air box before you re-jet.
