Interesting reading!As Brent said,we dont know the exact materials these scooter parts are made from,so its all a big crapshoot on what the proper specs are for them..The scoot aftermarket folks cant advise us either as they dont know what their parts are being assembled on!In the Mil-Spec world its all laid out for us and if its followed we can be certain all will work well..Without scientific testing($$$$) on each application its just a WAG (wild arse guess) which is the right assembly method...

I took the cylinder off and cleaned that up. Was just gonna see if I could get away with the new o-rings, but that's not fair if I'm going to torque a bit different. Installed it all as usual, aside from being certain there was no lube of any sort on the threads of studs and then torqueing to 5, 9 and 11Nm in steps. No one mentioned steps being my issue, and normally my steps are finger tight, sorta snug with a 1/4" ratchet and then final torque. Figured I might as well go all the way since we're scrutinizing my torque application.
This will prove nothing. As John said, 1 or 20 cylinders under various conditions won't prove anything. I guess I could have installed a new head, cut as the old ones were for squish, and then tried this. It would have at least been interesting to see if the thin walls cracked then. Didn't really want to get into a whole science experiment. I really just want it to seal so I can see if the crank comes apart where scored or if I can get the Lectron in tune prior to that happening.
Next thing I need to figure out for sure is how I'm going to handle the crank spline/spacer situation. The shoulder of the crank has definitely been machined a bit. Not planning to take it out and try to do anything about that. I'll need to make a new spacer. Thinking maybe leave it a little thin and put shims as needed between it and the crank shoulder. Maybe something of hardness designed for the application would be good. If anything has to sort of seat in, it would perhaps wear the spacer/crank and not a shim. I dunno. My thought is that you shouldn't have to worry about any of that if adequate clamping force is present. All of the stuff directly on the crank should be tightened together and not rotate independently so nothing would really seat in from just clamping pressure. Good reason to check the vari nut after the warm up ride and make sure there's no play.
I also considered boring out the splines in the ramp plate. I don't think I will though. My initial thought was that the plate could then sit wherever (with a key tacked to the rear of it). It should be able to sit wherever I want anyway though. I plan to use the old crank to position the key and the ramp plate so they can be tacked in place in relatively good alignment. Considering that and that the crank and other parts shouldn't rotate independently, I don't think there's any reason it couldn't move in or out on the splines if needed without doing more damage. Plus, if I bored it off center at all, it would be a disaster.

Leak test passed. Got the exhaust back on. Cleaned aluminum off of the primary drive shaft from the bushing melding to it. Installed a new clutch nut. Removed the old CVT cover bearing and what was left of the bushing and replaced those. Replaced all of the kickstart parts attached to the CVT cover. I still had to shim the bushing in the cover, because CVT covers aren't that plentiful at low prices and it's easy to end up with one that has the small clutch housing where you have to cut away essentially the whole thing to fit an OR pulley.
I came in so I could get cleaned up and not smell like kerosene for Christmas dinner, then found out that my mother didn't realize what time it was and hadn't even started so dinner will be about 8PM instead of 4PM. Don't feel like getting into the spacer now so I'll just do some editing if I decide to be more productive.
Merry Christmas fellas.

Merry Christmas back to you Brent. Thanks for all you do here for us and for Scoot-ees on the web. Sending good Karma your way.

I hope you enjoy dinner when it's ready. Was strange here. But the dogs enjoyed their dinners. Beef, not Turkey!

I'm a swindler now...
"You have managed to take a 30/25 size differential and make it "seem" to be a lot more, by using camera techniques and shadowing. On the one hand, that is good promotional work. On the other hand, it is a matter of taking a small difference and calling it a large difference, strictly based on your smooth and convincing manner of presentation. And presentation won't make anyone's machine run a bit better."
I asked what vid he was watching, because I'd be fired if I spent 1h16 minutes to install and tune a carb that I called expensive, with a throttle that doesn't return, hasn't matched previous times and that I never got in tune when they're always said to be close out of the box. lol
I got the spacer made today and welded the key on the ramp plate. Haven't had time to see how it all goes together yet. May need some adjustment on the spacer or shimming.

I think I’ve seen this method used in a video. Torque stick to the rescue!

In a small engine capacity, 30mm is quite a large carb. And a big step up from the 25mm Dellorto. How big do they think you need? The Kawasaki KX85 my brother had, only used a 28mm carb. And that's a race machine.

I mean hey, every Elite boy runs a 28 on their lightly ported 70cc cast cylinders and they swear by it 😂😂

Hmmmm'. "camera techniques and shadowing" ; you've obviously gone over to the darkside . I bet you were on Santas' "bad" list and didn't get any Xmas presents either .
