So sorry hessogood: It just seemed like there was going to be a kluge repair done. I just don't want to see someone due a bad repair just to get their bike on the road.
In my 48 years of riding motorcycles I have seen too many accidents caused by failure to inspect all working components that are supposed to work correctly. Plus stupid rider errors, including my own couple of screw-ups! That caused me such pain that I live with each day, my back is toast from a 70 MPH get-off.
And yes, I do know you, I have ridden with you before, & I think you are a great rider! it was about 4 years ago. PM Chuck (AKA 07bladerider) about me. Or PM me, I would be happy to talk with you again, we had fun on that night time run to the Blue Hills..... Too Damn dark!

Wasn't this bike already on the track with a setup that worked??

That sure is a purty shaft DB... : )
Yeah, my thought was that it's not really under any load. It just needs to keep the sprocket from coming off. I machined a high-grade stainless bolt a couple thou over the ID of the hole, warmed the shaft up, froze the bolt and stuffed it home in an arbor press. It was stuck in there pretty good on it's own, so I didn't want to go crazy with the welder and screw the temper of the shaft, so I just zapped it in a couple places. Since I didn't have the sprocket/spacer I had to guess at what kind of length I'd need for the threads and I wanted the nut to be able to bottom out on the shaft if it had to. So, I put the shaft in the lathe (with a collet) and machined the weld filler away, then chased the threads that had been filled with filler. Came out OK. I really wouldn't crank down on the nut, but there's no need to. Not pictured is a matching stainless nut and wavy-type lockwasher that should keep everything in place. I little loctite probably wouldn't hurt either.
Sweet job Mike!!!!
Anyone tried to put the sprocket on the splines yet? Me having the uneducated question, if the couple of thousandths larger bolt being pressed into the hole caused any interference with the splines on the sprocket or not? Working with parts that a couple of thousandths makes all the difference recently at work got me wondering.

Hmmm... That's an interesting question. I didn't mic it before and after. I wonder if the OD changed. I'd guess it didn't... or not much...
The fit between the sprocket and the shaft is generally really loose (by machinist standards) so if it did move I'd be surprised if it would cause any issues.
Nice work tricky!
Richie You should figure a way to safety wire the nut in place, maybe tricky could even add a little hole somewhere for you to do that

Nah, it's a really good question. This may not be one of them, but there are situations where a tiny change would make a big difference. I'm going to ask some machinist buddies what they've found.
Thanks, yo. I can put a hole in the nut fo-sho... You'd need a sprocket with holes, though. CS sprockets just laugh at drill bits.
ya I forget if richies had holes...all mine do.

Would the change in diameter go to the bolt or the shaft? I would imagine the force exerted but the bolt trying to expand would over power the force of the shaft trying to compress it, but I'm not an engineer so I'm curious. Could the shaft exert enough force to be compressing the bolt so the change in diameter would be transfered to the bolt being compressed as opposed to expanding the shaft.

I can resist everything but Pete's mom.
it really depends on how many thousandths over tricky went on the bolt...either way I'm sure he didn't go crazy and richie would be able to tap the sprocket on if there were any expansion.

Geez, sorry guys, just a question that came to mind. I really hopeit isn't, and don''t think it will be, even close to an issue for Mike and Richie.
Regardless, the work Mike did is bad ass and a solution to an otherwise troublesome problem Richie was having.
