spaz12 I have all his videos added to my scooter playlist and I am studing them especially the part where he grinds the cases to fit the big bore cylinder and matching the ports. But he didn't have any issues when installing the TD. Maybe because he used an after market gear cover from Polini? 'O'VerseWhat about friction? Are there gonna be any issues at 10000+ rpms when putting a washer behind there? Brent put also washers behind the TD in his videos but he didn't use a hyper race setup. I could slightly grind the TD like he did by letting it spin on the shaft. It is really just a tiny bit that needs to go.

They aftermarket covers are designed for the OR'S. I was thinking that he had another video with a standard cover, but I could very well be wrong.

There were a few other posts in other forums of people having the same issue. Most say they used a shim or washer. I am gonna go and look for a matching washer today and test fit it again. The TD clears it except for that spot. The TD seems to be not 100% round. Hard to explain by words so I will take a video today and show you. |

You just need to use the shim with it, little black washer. You may also need one with the clutch. The way the TD are stamped make them appear out of round at the outer edge. I made a warranty claim for one before and guess what the replacement had, the same thing.

I think I’ve used that one to space the TD from the case and a few thin ones for the clutch. It’s trial and error. Just try to make the belt as straight as possible.

And wider than your seal OD. In theory you’d be ok. You don’t want to push in or catch your seal in any way. While rotating. Then just periodically check the washer diameter for wear. |

Regarding the kick start assembly, the Jog one won't fit. So that mystery is solved which means before the build is finished I'll have to get a complete kick start assembly that fits a long case Minarelli. Otherwise I won't be able to start the scooter. I also added 2 washers (total 2mm) behind the Malossi OR TD and now it spins nicely without touching anywhere. I haven't assembled everything yet so not sure if I will encounter any issues later with the clutch bell or CVT cover but I will figure out something if problems should arise.   |

Those don't rub on the seal do they? I could imagine problems if they do.

Not sure what parts are moving and what parts are holding it in place. Normally if those washers wouldn't be there where and what exactly makes contact? The clutch bell and the gear shaft are one unit once tight down and only move when the clutch opens and grabs the inner of the clutch bell right? If the clutch is not engaged the TD just spins freely on the shaft right? So what is holding the TD in place? I guess I could just get larger washers that cover the oil seal completely. Still it might rub or cause friction on the gear cover edge next to the oil seal right? |

Here an interesting video by Brent.
Guess I'll do the same. Large washer first to cover the oil seal then one of those that I already have.

Without having an open cvt in front of me I'm just guessing, but I think that you would want as small a washer as you can get in there. Just enough to cover the inner part of the bearing race. Much like the clutch bell if it needs to be spaced you use a very small washer. But, again, that's just a guess. Post a picture of the shaft and cover without that washer, if you could. That would help visually. For me anyway.
And what holds the TD on is the clutch bell followed by a nut.

Atleast wide enough to cover the raised lip on your gear housing that's around your seal. That way your seal is more protected. The seal could then only be pushed back to the height of the raised lip. Then if it doesn't affect your belt alignment much. Use the spacer for added wear and spin.  |
