uneven tickover

[motostorm]

howdy guys ,

just wondered if anyone had an idea what might be wrong with my bike ,

i have an uneven tickover , bike was previously fine now it sounds like it is hunting ,

its not valve clearances ,

i have stick coils fitted ,

bike performs fine , its just a very uneven tick over ?? ive had to raise the idle to stop it cutting out , mechanically im pretty good , but just find this a bit odd and wondered if any storm owners have had this problem ,

ill probably start with plugs , but there fresh enough tbh ,

and if it was the carb idle circuit id expect up to quarter throttle hesitation etc ,

as i said , just wondered if anyone here has come across the same problem

Carb balancing,
Maybe a poorly performing spark plug
Maybe air leak (include exhaust in this)

Check all your fuel and air hoses.All clamps etc, probably an air leak. Check the carb rubbers as a small split may cause that too.

Are you getting popping and banging from the exhaust on the overrun?

Yeah, I thought that was a feature!

I'm thinking about a vacuum leak....

thanks for the replies guys im going to have a look , i do have an exhaust leak alright , ill check it out , and shout back , if anyone would like to offer an opinion , feel free , ill try to seal the exhaust and check for inlet leaks , check stability of the stick coils , and fit a set of plugs , throttle position sensor mod already done , probably be a few days before i get it checked out


just to add no noticeable difference on the overrun

just to add no noticeable difference on the overrun

Not even a bit of popping and banging from the exhaust leak? Any intake or exhaust leaks, more so intake will cause an uneven idle. The next thing I would be looking at is the mixture. Do a blip test to to verify things.
