well turns out it needed reeds, i took them out and one of them was missing.
put new yamaha reeds in it, run perfect. gf took it up and down the driveway once, her brother got on it and tried to race my 350x and we went up the street once, he topped it out in 6th...
turned around and on the way back he said it just died on it (i couldnt see cause he was behind me) and it wont start now at all... i took the reeds out they are still perfect looking... i cleaned the carb all out, new plug... won't start.
took the head off, the piston is intact, it has compression (not sure if it should have more, it wont push my thumb off the spark plug hole... but since the piston is in tact it should have some compression... if i look through the intake ports i can see the piston go up and down and it looks fine...
if i try and start it, there is gas in the carb, and in the intake boot, and also on the reeds, but the plug is bone dry. is there anything stupid that could cause this????
please help
