hi all, got a '00 yzf426 which is enginewise standard apart from fmf powerbomb header and powercore 4 tail pipe, basically i always need to use the hot start when its hot wether i turn it off or stall it etc etc, so its obviously a jetting issue, possibly caused by someone not rejetting it for the pie, but which way do i need to go? richer or leaner?
cheers

What if I pointed out that the hot start makes it leaner? What would that tell you?

Backwards.

If you have to use the hot start, that indicates that it is richer than it should be, at least on the idle circuit (pilot jet and fuel screw).
