i was doing some wot runs and it would cut out like its gettin not enough fuel. the machine identical to mine but stock will beat me everytime right from the start hes got a lead and we run pretty even and then my topend just cuts right out

 

sounds like the rev limiter?

 

wats a wot run? i think ive heard bout ur problem somewhere. ill look into it

 

it could either be rev-limiter or a possible dirty carb.

 

Might be time to clean your air filter when it's doing that. Mine starts to sputter WOT when the K&N is dirty.

 

i just put the k&n in there and the carb was recently cleaned, why doesnt the stock scrammy cut out at all

 

Go for a wot blast, don't ride after the run. Remove and read your spark plug.

 

do ya think its running rich

 

Mine done the same when I left the air filter top off, and it does it if its loose.

 

ya mines not lose but i just put the k&n in there
