Hello, I have read over numerous jetting threads (thank you Eddie) and believe I found the appropriate settings for my bike/situation. My bike is a 2009 DRZ 400 mostly ridden at near sea level with the following mods: 3X3 (thank you TT you tube video!) full Yosh rs2 exhaust athena big bore kit (440) Dynojet stage 2 kit (oem #3110) with the following jetting. 160 main jet dj needle clip 2 dj slide spring stock pilot jet 2.75 turns fuel screw The bike starts great, idles great, and is a monster under heavy throttle. My question is when I am ,not a hooligan, just cruising with the throttle barely cracked (maybe 1/8) there is a slight hesitation or surging. When I bang the throttle it pulls like an angry donkey, not hesitation. Is the cause a lean pilot circuit? Opposed to getting a 25 pj, can I get away with turning out the A/S another 1/2 turn or so? Cheers and thanks in advance for any help. S.
