Hey guys, great forum. Thanks for all your help. I have a 87 Trail Boss that does run. It had a complete overhaul many years ago, but not much time on the motor. It is a bear to start and I understand many of the problems that are associated with this. So I pulled the engine. No big deal. Lots of questions to follow. In advance thanks for your help.

Guys the tb250 keeps getting into smaller pieces. Order parts this morning for oil seals and the recoil seals. Pulled the head and see nothing that tells me I am .10 or .20 over. The head says: 1.00 mm, 536p4, cd with and arrow forward. I would guess it would have something to tell me I am over bored. So will order rings. Had head and case gasket on last order. Say how is a 1987 different from an 1988? I ordered the carb gasket jet and floats and needle valve for floats. Eliminating what I can to help the hard starting
