So this bike likes no jetting whatsoever nor does it like any needle, or any needle position. Its a big bore rm250 to a 265cc. Has fresh crank seals bearings crank top end reeds etc. Is hard as heck to start by kicking, will only kick with throttle wide open and spits fuel out the overflow hose when doing so. Adjusted the float every way possible, no difference. Fouls plugs like crazy. Went as lean as possible on the carb, made no difference. Spooges like no other. Wont rev clean into the mid/top powerband. Smokes like crazy when at idle and low rev range. Does anyone have any clue? Powervalve was clean and opens/closes freely. It will bump start fine and start first kick when warm/hot.
