Okay Gang, I think I know what I did wrong, but let me explain it first. I put in the new TB 88 kit, fired up the bike and ran it up the street once and back down. Very nice improvement. However, I then realized I was so excited to try it out, I didn't add any oil to it. So, I added oil, started it back up, and after about 30 seconds it was smoking pretty good. Tore it down, checked everything again, started it up, and the same thing happened. This morning, took it apart looking for a possible gasket I may have missed, removed the valves, cleaned them up, removed a bunch of carbon, I DID NOT LAP THE VALVES OR REPLACE THE VALVE SEALS, out it together, started it up, and back to smoking again. When back and retorqued the head nuts, and got the same. I am guessing I damaged the rings and might need to replace them. And yes, I am very meticulous on placing the rings in the correct offset so that is not the issue. There are some spare o-rings from the kit. some very small green ones that look like possible valve guide seals, but not sure. Anyway, let me know if you have some fresh ideas. The older posts either ended before a solution was found, or their solution didn't work.
