1985 Kick Start Idle Gear

(1/4) > >>

motojason:
Wondering if anyone has experience using a later model kick starter idle gear in an 85 bottom end? I know the tooth count changed in 86. Thought it might be possible to change the clutch basket, idle gear, and spur gear from an 86 to 88 and get it to work? Has anyone tried this?

Thank you,
Jason
 

motojason:
Will post some pics over the weekend.

The 85 idler gear (27T) has one broken tooth, but everything else is in usable condition.

Alternate to replacement:
Is it possible to repair a gear? Could it be welded, and the tooth rebuilt and the gear heat treated?
Anyone know of a shop in the US capable of doing that type of work?

Thanks!

Hey Jason,
Just to let you know, the one you need - FITS 83-85 KX500 - P/N 59051-1107
I would look on eBay every day.
You might also want to fine a complete engine or a bottom end.

Motorrad:
What's the tooth count on the new one?   Some times like on transmissions they change tooth count on only one gear.

motojason:
Yes, 83-85 should be the same (27T) gear, thank you. Have been looking on ebay for months, calling salvage yards, and putting feelers out to the vintage race community. No luck so far. I got out bid on a bottom end that was in MI, but that was in early March and there has been nothing since.
