Engine sound rough with jetkit needles
Hi all,
I am just wondering (base on my hearing). Why after switch jetkit needles engine sound rough, engine sound not smooth with stock needles. Do you guys notice about this? I prove it when engine sound rough then I switch to stock needles then engine sound smooth again. I doing this just to prove it. Don't ask about performance hehehe....huge different. |

If the rough sound only happens when the engine is at idle, then you need to adjust the idle mix screws:
