it might have right around 100 miles on it, maybe a tad more...not too much.
the idle jet wouldnt affect it at wot, would it? i was under the impression that it was only up to maybe like 1/2 throttle? i'm going to order some and i'll grab some in the 40s and just adjust the mixture from there.
while its off, i'll chamfer the ports, replace all the gaskets and make sure everything is sealed good and clean up the sleeve on the case to make sure nothing's rubbin'.
