I have a 2008 trx 250ex, I have put a hmf exhaust system on the bike and I now need to re-jet the carb. anyway I wanted to know if I take the carb off the engine to put in the new jet that I have for the carb, can i make a new gasket to bolt the carb back up to the engine? or will I have to buy a new gasket? thanks. also what is the torque spec for the carb bolts? thanks again.
