Okay so I recently picked up a 17 150 SX. It’s for my stepson. He has been complaining of it cutting in and out if it’s not wide open. I’ve only ridden it in the sand and noticed in 2nd it ran like crap until it cleaned out then all good. I thought it was maybe just super rich everywhere. I put in the JD kit while at the track today and it seems to run cleaner everywhere except mid revs mid throttle just before the power comes on. It’s like a rev limiter and the bike surges. Super annoying coming out of tight corners where I have to get off the pipe. Any ideas? Going to be pulling the top end apart in the next couple days just for a routine inspection and piston change. Anything I should be looking for in the PV?
