Thanks for the timely reply Jim. I'm not too much of a motorhead, so excuse any dumb questions. When you say to 'strip' the engine and take it apart, what do you mean by that? What should I be looking at specifically? Thanks in advance.

Hello I have a question regarding a 74' Yamaha TX500. I have just had it serviced (its been sitting for 25 years). Carbs rebuilt, one new (used new) ignition coil, and a cleaned gas tank. The bike runs fairly well, but I'm having two problems. First, when the bike gets good and warm, it idles to 4000 and wont come down for quite some time, and when it does it stalls. Second, there is white smoke with a gassy smell, quite a bit of it, coming from the cylinder head/crankcase breather tube located on the left side, top, and back of the engine (routed down under the bike), also only occurs when she's good and warm. Any ideas?
