Bad battery
Bad starter
Choke jet not tuned right
Valve adjustment wrong
Worn rings
Bad fuel
Bad reeds
Air leaks
Those are all I can think of atm.
Bad battery - brand new battery and after it starts and runs first time...you just tap it and it fires
Bad starter - think this relates to above
Choke jet not tuned right - is this the enricher? I dont think its working, it never revs up after starting initially
Valve adjustment wrong - 2 strokes dont have valves right?
Worn rings - I just installed new top end less than probably 150 miles ago
Bad fuel - new fuel, also ran in my other scooter just fine
Bad reeds - this may be it. Never have messed with them. Would it be smart to replace just for good measure?
Air leaks - maybe, but I try to really tighten these all down and make sure its sealed up
Those are all I can think of atm.
Thanks!
