So i have a 93 f2 w/ over 38k miles
it is a california bike
w/ 49 state cdi
cali carb w/ jet kit
full hindle exhaust
intake filter

my issue is when it gets to operating temps or higher
after i let in the clutch or go to neutral the revs tend to stick around 2-3k rpm and stay there for a little bit.. afterwards it goes back down to 1500..

we cleaned the carbs out recently but i wonder if something could be wrong.. any suggestions? Thanks

 

Could be a vacuum leak, or not thorough enough on the carb cleaning

 

any idea which vaccum lines it could be? it doesnt happen when cold..

 

throttle cable sticking.
not good enough carb cleaning...
