Looks like that cam lobe is a tad close to the dizzy idler gear, Trimming the cam lobe would be easy, no?

Clearance looks good....
Some fellas bitch bout Helicoils pulling out, but if installed properly, one full turn below the top of the hole, they should be good for the life of the project. I have found that 1/2 turn works, but only if I feel I really need that extra one half of a thread in a shallow hole.....

Since this crank is what it is ("One off" would fit really well)

Thought I better check the oil path to the pinion shaft ...

Image

Image

Looked like it was a bit off, with a little burr action made sure the path was open ...

Dang, got alot of slop .. :shock:

Gen is a Cycle Ele (65-A type) most likely the gear is aftermarket cause it's loose on the spline ..
Who's holding a Oem gear .. ??

Not much need on this motor cause it's still a side oiler ...
If I converted it to a end oiler the weep hole would have been plugged ..

Here's the gig on the gen gear ...

Image

Super loose fit on the splines ...
Don't know for sure, but do think it's a aftermarket gear they have a loose fit on the splines right out of the box.

I found a Nos Oem 13T that takes almost a press fit to install ..
Since I'm thinking this motor will be seeing a mag, a bit faster spin at low speed won't hurt a thing ..

Need to make a bolt for the case ... :cry:
Then send it to the chrome shop ...

That will slow down the assembly ...
