[QUOTE="NickyV250f, post: 196385, member: 3491"] got a deal on a 05 yz250f. Rode it for day and realized it didn't cold start the easiest. Went to check valve clearances and exhaust were in spec but intake were all too tight. I put the smallest shim in and still way off the tightest spec. The original owner installed new crank, n cylinder kit and I'm guessing it's still the original valves in the new cylinder. Do I just buy new oem valves? Your info greatly appreciated. [/QUOTE]
