Automatic chowk
on: September 07, 2015, 10:48:42 PM
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

They don't have a "choke" anymore, it's done electronically by the ECU.
There will be something that is loose that will not seal properly until the engine is sufficiently warm enough.
Or a vacuum pipe that's loose, pretty much anything under the fuel tank.
If your not minded to have a go, take it to a man that can.  :027:

Hi All
I thought I would report back. it turns out there is some type of automated/electrical/ECU controled/part mechanical choke in the Crossrunner.
Honda dealer found it to be faulty.
I noticed this problem for once shortly after the 6oo mile service then nothing. but problem just came back nearly 20k miles later.

Now I know why my bike' engine idling speed apeared higher than it should.

Anyways all is sorted now.

Thanks

The VFR engine has had an automatic idle advance (not a choke as there are no carbs) since the introduction of the VTEC.  Before that the VFR had an idle lever that was moved forward to give about 2000 rpm when starting and retarded after a couple of minutes.  The CR engine should do this automatically.
Glad you got yours sorted.
