My manual says that choking while in motion is acceptable, so long as you turn it off after 15 seconds above 68 degrees F, 1.5 minutes under 68 degrees F, or 2 minutes below 40 degrees F. Also, don’t exceed 2500 RPM. And don’t choke for more than 5 minutes under any condition.
I have no problems starting when the bike has been cooking in the sun. If it’s in the shade in the day a little choke is needed, but using the throttle to keep engine speed up for a few seconds then slowly dropping it to idle works, too. Note I said slow. The trick whether using choke or throttle is to reduce engine speed slowly, not watch it dive down, because it’ll drop below idle and then you get the angry red oil light and a stall. And if it’s a cold night, then choking is a def, or else the problems as mentioned in the post a few up happen.
