I've run almost 5 tanks of gas and it's well broken in and been running great. I was about 15 mles into a trip going around 30mph and the bike lost power (full throttle got me 20 mph). I tried to shut it off but nothing happened so i braked to a stop which cut the motor off. It then smoked (from the motor not the exhaust) And now when i try to start it it makes a high pitched noise instead of the usual throaty turn over. I've been running it a little lean i think so that could be it? Please if anyone has any ideas to fix it i need it to ride to work.
