just bought an 06 TE 510 over the winter for my sumo setup. rode the bike in the early spring and noticed it smokes whe its cold, but clears up after a few minuts. Im pretty sure its the valve guide seals, but im not 100 percent. I know if it smokes uner acceleration its the piston rings and under deceleration it would be the valve guide seals. once its hot it doesnt really smoke at all, then again its hard to ride with ur head spun around with 50+ hp on tap. does this sound right? is it a big job i should leave to a shop or is it something i could tackle myself.
