no problem. and on a 2stroke it goes backwards. rich will pull rpm's down. lean will bring them up "lean rev" unless we are talking a alky bike then extra fuel will cause high rpm's.
it's dying because it is ffouling the plugs with fuel. a bike should die if jetted properly and at temps... the extra fuel is for a cold combustion chamber. cold equals more air which needs more fuel.
lol i told a doctor once that it hurt when i lifted too much weight.... his response? stop lifting too much weight.
in other words stop pulling the choke while its running lol
puking antifreeze is typically a sign of lean condition. cool motor but scolding hot pipes would indicate rich. 310 seems a little lean for a sea level bike with pipes and pods.
$300 shipped on the cylinders
$80 shipped on the head.
bottom dollar here guys or they go on ebay. i have seen members pay up to $200 for virgin bore cylinders. you're robbing me for my polishing labor at 300....
