My cross runner is the mark 1.
I am not what is causing this but i will try to explain my best.
engine start from cold , like in the morning when going to work, the following happens.
Bike starts normal, rev stays a little high to while engine temp rising.
normally when engine temp reaches above 50c, the engine used to return to normal idle(about 11000rpm). but this time it does not, infact the auto choke seems to keep the revs up until engine temp gets to above 85c. or even 90c.(this takes really long time,.
plus if I rev the bike via throttle twist, it kinda gets stuck at about 3000-4000rpm for couple of secs(some times does not come off at all and stays stuck at over 3krpm the goes back about 2000rpm when I twist throttle grip more. this crazy rev time keeps happening until bike gets worm.
Basically all this means is my bike throttle appears to sticking until it warms up.
the bike did not do this until last couple of months.
Does anyone heard of this?
My throat cable has been lubricated well, so no idea what is going on with throttle when bike is cold.
this never happens when bike is worm. only cold.
Any thoughts will be great.
Thanks all
