KX 500 Flat on Mid and top end
Motorrad:
where did you measure the piston BTW?
you know Pistons are egg shaped from front to back right?
measure them, you would find that many pistons are as much as 0.010" out of round. (all bikes)
lsampson:
sorry about that, so what is the best way to check piston-wall clearance? I used a feeler guage, slid it between the piston and the cylinder on the intake side of the jug, and let to drop to around mid-bore, and came up with .127mm with the new wiseco. The box states .100mm is the clearance on the box.
lsampson:
I measured on the skirt, 90 degrees from the wrist pin. Thank you for the help. I'm not totally ignorant to this stuff, but this one has me stumped.

the more and more we dig on this. the more and more you need to go to a local machine shop and have a bore guage stuck int hat thing...
somthing aint right.
or if your local to san diego. We can do it.
lsampson:
I will try to take a pic, and like I said I'll be measuring the bore tonight. The cylinder looks good. I can still see the cross hatching in the walls in most places, and no significant gouges
