Adjusting Choke Lever

Anyone managed to adjust this lever correctly?

I've adjusted the cable to take up a little bit of play I had in the throttle, but can't work out how to reset the choke lever.

Tried loosening and tightening the screw, and repositioning with/without throttle applied, but no joy.

Also curious about this as mine does little or nothing when engaged.

Throttle adjust

The throttle cables operate on a pull to open and pull to close. The little "choke" lever just operates on a cam basis to slightly open the throttle. Choke is a misnomer as it is not a choke lever, it merely rotates the throttle a fraction. If the cables are out of adjustment esp the throttle opening cable, then rotating the toggle lever will merely take up some of the cable slack and not open the butterflys...which is the desired effect.

So , you will need to adjust the cables under the tank in the time honoured fashion until there is no slack. Not too much though or you'll open the throttle at tickover which isn't what you want.


These pics just show where the cable adjusters are under the tank...I was doing something minor at the time like changing the frame which necessitated taking the throttle bodies off the engine.; )

Cheers Joe,

I've already adjusted the cable to the point where the throttle doesn't quite return smoothly, then backed off so there's perfect throttle opening and no slack.

I'm at the point now where the choke lever is doing nothing. Before I farted about with it, it was at least opening the throttle in the last part of its quarter turn.

Do I need to reposition the lever somehow, or adjust the position of the cable?

I have noticed that when replacing the 8 year old throttle tubes along with my stock grips, the hard plastic "tunnel" that the cable sits in has been worn down a bit from when new (from what I imagine to have been new as I've never seen a new throttle tube) and rendering my "choke" lever inutile.

Adjust the other cable, not the one that tightens up the rotation, and do it with the "çhoke" lever in the closed position.

Not much joy really.

Slackened off the lower cable (the return) completely, full thread showing. Adjusted the upper cable just shy of point where it stiffens the throttle, about half thread showing. Choke takes up cable in the final few degrees of turn to open the butterflies slightly. Guess there's wear there that can't be adjusted out.

Are you adjusting the cables at the grip end, or the throttle body end?

Keep your words soft and sweet, for someday you shall eat them....
