Hi

When I run my bike hard and fast and it get s hot I lose my ldle when slowing down or stopping and I'm also getting very bad back firring when I slow down to.
The over heating program on the bike was turn of by the dealership but it's still happening and getting worse.
The dealership say they can not get it to happen for them when I bring it in 9 times in the last 2 years.
Can some one help me here? it's killing the fun of ridding the bike.

 

is the bike stock?

 

Has the bike ever had any work done in the cam area, e.g. a cam upgrade, tensioner replacement, etc.? Does the bike feel sluggish after it warms up? Your symptoms could point to sumping, which is oil accumulating in the crankcase and not being scavenged adequately. When this oil accumulates the flywheel can strike it on each revolution and that can cause serious performance degradation and overheating.
