Mark,
what do you have for intake , stock airbox or no box and K&N.
it sounds like I want to agree with chopperpaul.
it may be to rich.
though with the stock pilots I would think not.
start the bike cold with the choke pulled ,
just let it idle , do not touch the throttle.
if it dies , it dies.
then check the plugs.
this will let you know if it is a rich condition.
if not , I do not know what to think without more
up close and personal tinkering.
