G’day Guys.

Further to the vibes I’m experiencing with this 610 I’m wondering whether the balancer has been left out by the previous owner. Nope.

What I’m seeing is two balancers. One above left of the clutch and another in the opposite side in behind the stator cover.

Can someone give me some input on these two balancers? Obviously one is a counter balancer for the crank assy, but the other?

Thanks guys.

Al.

Sorry guys, I have worked it out. The balancer on the stator side is part of the the same balancer assy on the clutch side.

Next is to check these have been assembled correctly.

Balancer is all good and dots aligned. Bugger!

For those that have done bent Berg engine assembly, can you verify whether the split in the thread of this gear is of OEM?

It’s on the crankshaft. It’s connected to the starter by a couple of idlers. The top section of it is in behind the balancer.

Ayyy, I would doubt that that is OEM. I have no concrete knowledge though.

(Thanks for the informstive and already useful thread!)

Once I zoomed in Jon I could see it wasn’t factory.

The one off the spare engine looks healthier. I’ll have to source another for this spare engine so it can be turned into a 610/662.

Hi Alan,
the gear with the crack in the thread is the 78032000233 (original part the bike came with). The spare you have is already the first revision of the gear (78032000333)! Who knows why it has been changed... maybe you found the reason.

Like to read more about your engine conversions.

Regards, EDE

Oh thanks Ede, I didn’t notice. It doesn’t look any beefier, not that I put them side by side.

Anything you’d like to know about the bikes just ask mate.
