Finaly Got the Pipe and Velocity Intake kit on the Z400.... I went from a 135 main to a 170 Main jet. But Now There is a slight Miss/Studder in the engine once it is warmed up and at high Rpms. When the engine is first started ( First few mins) i can open it up and go through all the gears wide open and it is perfect...But once some heat gets in the engine.. it starts to miss. I mainly notcied it when i was racing my buddy side by side in a strait line on the pavement. In 3rd 4th and 5th gear.. once the rpms got close to hitting the Rev limiter it would miss out just a little bit. and if i slowed down..and rode in about 3rd gear and went to ride a wheelie down the road it wouldnt do it becase the engine had a slight miss at high Rpms. But when its cold the thing will stand right up and go as far as you wanted on the back tires. SO im guessing I need to Rejet. But what would you guys recomend me going too...or any other sugestions...Ohh BTW im running 92 octane fuel if it matters. Thanks,Chris. Heres Some Pics:pics:
