Re: how to use the choke
I usually never choke or prime mine.
If the bike has been sitting for longer than 2 weeks (If im planning it, I shut off the fuel and drain the carb bowl), I turn on the fuel, give the gold button 5 pushes, then set the choke to half, and crank the motor. When she fires (you'll hear it 'pop') you release the choke fully and attempt to start it again, assuming it didnt stay running. Once it fires, immediately pull in the clutch and let it idle for about a minute (itlll be smokey) then rev it up a bit and you're good to go!
If the motor has only been sitting for a short period of time, simply crank it until it fires, pull the clutch etc.
In fact, I think a lot of people have questions about the 'proper' way to start their motor. This deserves a thread.
