Hey guys wondering If anyone had any input on this problem I'm having. I have a 2000 drz 400 e with the fcr 39,it's got the big bore kit, stroker kit,3x3. It is jetted at 160 main and 45 pilot and I'm at sea level. When I rip on it pretty much 0-1/4 throttle it bogs and is real jumpy, especially after I up shift. But after 1/4 throttle it runs great. Carb was recently cleaned, not sure what the next step should be matey changing pilot?
