'89 KX250 Project

Definitely! I'm the type of person that enjoys learning about and working in these things as much as riding them! ;)
Two weeks ago I had never laid eyes on a KX250 in person. As of a few days ago, I've been through the engine, top and bottom. :-D
The drive gear for the governor shipped out yesterday, I'm hoping to have it by the weekend so I can get the engine back together. Yesterday I got the top end back together, repacked the silencer, and buffed the rust off the pipe. The bike is looking better and better everyday!

Just an update...
The gear for the governor came in the mail today, so I put the bike back together and got it running again. The top end power is MUCH better than it was before. Now it's running the way it should. :-D
I've got a new problem however... The bike loads up bad when it idles. If it idles for about 30 seconds, then I get back on the gas, it sputters and smokes BAD until it clears out, then starts hitting hard again. It wasn't doing this before I cleaned up the powervavles and got them working again. Could moving the sleeve make that kind of change in the carb. tuning, or maybe the valves? (they were stuck closed before)
I tried to adjust the pilot screw, but don't really know how to tell when it's close, I've never tuned one of these before.
Any ideas?

I put a sleeve in an 89 years ago and couldnt keep a head gasket in it. I dont think the steel liner transfers the heat properly . After going back to a stock lined jug I never had another problem. Keep an eye on your coolant and overflow tube. Good Luck
