Kick start and clutch operation

<< < (4/8) > >>

CB-500:
So with the clutch pressure plate, friction plates/discs and clutch centre hub removed this leaves just the clutch outer housing on the main shaft

Turn the engine over via the crank - this turns the primary drive gear clockwise which turns the clutch outer housing anti-clockwise

Being careful with two long screwdrivers I’m unable to turn just the outer clutch housing on its own the same way (anti-clockwise) in an effort to turn the engine over like the kick start would

Am I missing something?

I'm mystified, be interesting to read the fix when it pops up.

Hahahaha me too!

McCabe-Thiele (Ted):
So when you rotate the crank the primary drive chain is rotating the primary drive shaft as it should.

However rotating the primary drive shaft results in such a load that the crank will not turn either via the kick start when the clutch is in place or by hand using screwdriver levers when the clutch is removed.

Could this be connected in any way with the starter clutch hub as I can't see what else could be causing the issue?

You should have a glimpse of this mechanism when the sump is removed.

CB-500:
I was thinking down the same lines at first - but the idler gear for the starter motor in the top crankcase locks in the correct rotation and free wheels in other - So it appears the starter clutch hub is working as should

Never the less trying to turn the outer clutch housing anti-clockwise isn’t asking the drivetrain to do anything different then what it is already doing when I turn it at the crank
