yep, if your motor is close to stock, i would put in a 40 pilot jet. also, when trying to start the bike don't keep hitting the gas. you might want to pump the gas 2 or 3 times. then just hit the start button without giving it any more fuel. hitting the start button will just make you flood the bike. some people have better luck not using the choke while sometimes i find it better to use the choke.

i would first just go and get a new plug. by the way, if you can't get it started for 3 hours. i would push it down a hill or have someone else pull where you can drop the clutch to fire it up.

also, those aftermaket rev boxes will make the bike hard to start. now they make some that don't give you problems though. so if you have one, take it off for winter.
