Well i bought a used stock cylinder, head , piston and rings off of a guy in cleveland. I put them on and two kicks and it fired right up. This is after midway yamaha told me my cam was bad. I guess that they just wanted to take me for a grand. I am laughing last. I have a total of 200.00 in my blaster now and it runs. It still spits and sputters a little, but i am giong to clean the carb, and check air filter. Also, the bike ran like crap until it blew the second half of the exhaust off. Maybe my muffler is clogged, or something. If anyone has any helpful hints write me at email@example.com. I can never find anything i write.
