Postby PeterB » Tue Feb 11, 2020 12:53 pm

Hello,

Question : how to find the right ignition time....for a KH
See attached picture. This vertical line shows the right flywheel position for a KH
BUT ist this the right position with using the left handle bar for cold start or without using this grip ?
Th ani’s in advance
kind regards
Peter

Peter, try the link below that has lots of info on timing. Timing is set with spark fully advanced - left grip is in same position as right grip at wide open throttle.

Hello,
thanks
So both handle grips are full turned in driver direction !? But why the right throttle one ? Can‘t understand for adjustment.
We are talking not about starting process....
Also where is the logic for the left handle grip to adjust an earlier full ignition time which is only necessary for the start.
So the rules for adjustment based on the start position instead of the regular driving status.....strange
greetings
Peter

......only to make sure to get no misunderstanding......both handle grips left and right should be fully turned open in driver direction...

( sorry for bad english )

That's at full throttle.
At idle, the opposite direction.

Peter, the timing mark should align with grip fully advanced. Retard only for poor fuel, spark knock or long hills etc. Some folks retard to start. More important is to prime two revolutions full choke, ignition off. Slowly wind engine to BTDC. You feel pressure on starter pedal. Choke to 3/4, 1/4 throttle open and ignition on now go!

I referenced the throttle side grip only as an example to be clear on direction of ignition grip rotation. As you stated, only the left grip has anything to do with setting ignition timing.

In response to your question about the function of the ignition control, it is rolled away from you to retard ignition timing for starting the engine (timer should rotate CW to stop). This is done to reduce/eliminate the possibility of the engine firing early which can cause the engine to rotate backwards during the kicking motion, and can result in the kicker arm rising rapidly and spraining or breaking your ankle or knee. Immediately after starting ignition timing should be fully advanced (grip rotated all the way toward you) and should remain there until you need to start the bike again.

As others have stated, ignition timing is set with distributor fully advanced (grip rotated all the way toward you, which should rotate timer fully CCW against until the timer is hits the stop [motion limiter on base of timer]).
