Hey, I need the number of your Sponsor! :-D
You won't regret rebuilding the old girl, and then you know how it's put together. I can't tell you how many friends drop stuff off that "only had 10.hours" on them or were "Freshly Rebuilt" Oy-Va...
Get yourself a service manual if you can, worth every penny..

YAY, the sites back up! So an update. I tore into the motor, replaced all bearings and seals. Cleaned KIPS, replaced the rod guide, the o rings and stuff like that. Put in a new proX piston since the wiseco that was in it looked like garbage from just a couple hours. Anyway, fired the bike up and same issue. In trying different things, I accidentally started the bike with the petcock off and after 30 seconds or so when the bowl started to run low the motor started running really good and sounds great. This makes me think its carb problem. So where im at now is 55 pilot, 165 main, needle second from top, 2 turns on screw, new needle valve, tired all combinations of float levels, carb is spotless. I am not sure were to go at this point. Anyone have any other ideas?

it could be the "needle seat" in the carb is worn....allowing it to dump excess fuel in.
Do you have another carb kicking around you can try?...even if you borrow one from a buddy, just to see if it makes a difference.

I was thinking that but I didnt see that as a replaceable part in the Kehin or Kawi parts diagrams. I do not have another carb. Anyone know if the seat is replaceable?
