Trs not running right


Recommended Posts

Hi all, Ive recently bought a 2018 trs rr 300 that has hardly been used and went out on it for the first time yesterday but I’m having a problem with it when your riding it at a constant speed it’s slightly surging forward and back, I wouldn’t say it’s missing firing.

what are the problems when the cdi is playing up

Sometimes people lose the needle jet when cleaning the carb. Some bikes run poor to fair in this condition but will not run great.If you take the airbox off at the carb, there should be a brass coloured bit sticking up from the bottom of the carb. That part is the needle jet.  Good luck.

Is that the black plastic screw or the brass one that is counter sunk into the carb

It's the the horizontal brass one that is closest to the airbox Other one alters the tickover speed,gets faster the more you screw it in
