Mancat , please define ' overheating ' as the only time valves can possibly cause hot running is of they're too tight and i know you cold set them to .002" .

It's definitely running too lean. This has been confirmed now. Spark plugs came out a little burnt recently, and it has always had what sounds to be a bit of a ping. Timing and points are spot-on. I went ahead and adjusted the valves to .003 (yes, they were previously at .002) just as a test run to eliminate any overtight clearance - valves were a little chattery, but the bike still overheated and seized up (never seizes hard) on a WOT hill run. I already ordered the DrATV carb rebuild kit with 65 and 75 jets.. b52bombardier informed me that some 1970 California CT90s had a 62 jet, and lo and behold mine is an early 70 K2 originally sold in Oakland CA (still has dealer stickers on it). I haven't taken the carb apart again (forgot to ID the jet the first time I had it apart) but I wouldn't be surprised to find a 62 jet. Never had the heating problem when I first got the bike and it was still ~30-40 deg in the morning and evenings. Now that it's into the 70s, it's very touchy on the road. Can still put around on trails as long as I want. I won't expound on this any more and fill up this thread. Just wanted to answer your question.
