My jetting is not right!!!

[REDARMYRACER]

the bike runs great when it's winding out every gear, but under low rpm a stab of the throttle it only sputters. my hill climbing abilitys suck now too. the bike just isn't running good unless it can really wind out the gears.

i got a full pipe, hrc kit, esr intake, with a 205 main jet

any suggestions on what to do would be appreciated.:confused:

You may need a bigger pilot jet. I dont know what stock is but try a few sizes bigger.

You might try adjusting your fuel screw if you haven't already.

I had to rejet when i got the CS pipe. I went to a 190 main(f185),50 pilot/slow(f48),5th clip on the HRC needle(f 3rd), and 2 1/2 turns on the air/fuel screw. That got rid of the throttle off deceleration popping that i got when i installed the pipe.:D

check your plug, but a 205 seems way to big. Id say it should be a 195 or smaller, but no smaller then a 185.
