Title: revs bouncing
Post by: tdh-syorks on April 20, 2010, 03:19:07 PM
Since putting my new red and thermostat housing on my g has started to skip between 800 to 1200 mainly when I dip clutch to pull up at the lights, it doesn't do it everytime but most of the time, any ideas, cheers Tom

I was actually wondering weather the cable was too tight and one of the micro switches on the tb was pressed

sam had this  on his and it was like it was idling too high so tried to cut fuel and was too low so went back.  He wound in the idle screw and it cured his.
