[QUOTE="dkgoodrich, post: 1273966, member: 80065"] Did a compression check on the rm and ktm also a vin check Turns out, 01 RM 125 - 70psi 00 KTM 125SX - 140psi Tore down the rm and it looks like they ran it with no coolant or it burned it off because the middle O ring in the head, half of it was missing I mic'd the piston to buy another one and its 55.86mm. and the pistons I found said std bore for a 01 is 54mm.. hum.. On the ktm I tried backing the black thumb screw [only screw I could find on the carb] out and it seems the idle droped a bit and may have helped a little power wise but really not much. I have been reading up on the power valve and how to maintain it and replace wore parts. I am also going to start reading up on jetting and carb settings, of which I have never delt with. Any thoughts? Thanks for your time. DK [/QUOTE]
