oil should be the first thing you change out, get some fresh stuff down in there. running with no airbox or airfilter, big nono. could of sucked anything into the carb and possibly the motor itself, throw that airfilter back on it and if you aint using a airbox, get an outerwears at least. reclean the carb since there was no airfilter. check your fuel line, change if neccessary. if you got spark you should be good there. as for the battery, do you have it grounded good and are you turning your key off if it has a keyed igniton. and why on earth would you fire a bike up thats been sitting for a while, and as soon as it starts kick it in gear and take off wheeling it? you should let the thing warm up a bit, get some oil sloshing around inside the crankcase and running thru the head first before you beat the thing. good luck getting it running. i love them little trx200sx's. i have always want to mod one up with an x motor and maybe do something to the suspension to make it more sporty. see your in wallkill, how far from albany?

Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"
