I posted this before,like a month ago but when I was driving my variator nut came loose,causing the variator fan to rub on the cvt cover,I heard this and immediately shut it down,when I removed the cover the nut was loose and I could see scuffs inside the cover,nothing too crazy,but now when I went to pull the drive boss off its stuck,someone suggested wd40 I tried that with no luck,could I use a puller,like position it behind the variator ramps,I'm just really Leary about using any tools on it and screwing up the splines.has any one else had this issue? Also my valve cover is leaking,I would like to use rtv sealer in conjunction with the gasket,what type can I use that is not permanent? Thanks a lot guys I heavely depend on my scoot to get to work in the summer months!!

Nate7504,
I can't advise you on the variator... Yet... But, I think I am having the same problem myself. I just put my scoot back together after making several repairs and mods, and after a short test-ride, I'm hearing a metallic rubbing coming from my new variator. Gotta get in there and see.
On the valve cover though, you can probably use one of several things. I've used the "black" high-temp silicone RTV sealant available at auto-parts stores with good success. It dries to a consistency similar to a factory "rubber gasket" and is recommended for valve-covers and oil-pans. It's good for up to around 500 degrees, and can be cut loose from metal with a knife. Often it can be mostly pulled loose and the residue scraped off with a knife or scraper. It's good stuff.
The jury's still out on the variator though... LOL!
When I find what's wrong with mine, I'll post a thread on the repair.
Ride safe, wrench often...

I had the same variator problem. Took my time to get it off using an array of tools. I noticed the grooves in the variator hole nearly stripped out. There is such little shaft sticking out when i put the variator back on.
Is yours a high performance variator? Mine is. Maybe that's an inherent problem with a performance variator. Mine is Koso.
I figure the drive boss does not spin on the shaft, so if it's stuck it should not be a problem except when you want to change weights. I carefully greased the variator onto the boss so no excess could cause problems.

It will work either way. Your choice.

So should I use sealer with the valve cover gasket,or just the sealer?? I reused my CVT gasket and put nothing on it no sealer - It was stuck to it already. Fits perfectly on just tighten the bolts around it. I used a malet and wrench to knock the variator nut tight while holding the variator fan with the other hand.  |

About the stuck variator parts... I removed my own CVT cover, and found the noise was a torn piece of gasket material from the original CVT cover gasket. You never know what's going to make a strange noise...
With your stuck parts, I thought back to "the old days" when I was working on 1950's Harleys. If you can find some, I had EXCELLENT results using the old, original "LIQUID WRENCH". I think it's been around longer than I have... LOL! Instructions say to put some on the stuck bolt, shaft, etc. (it comes in a small "oil can" like "3-in-1" oil) and then tap the end of the offending part "to set up a vibration". Let it sit a while, then try removal. If it's still stuck, try again.
Sounds a little strange, but it never failed me! Even got a head-bolt out of an old Buick which was SO stuck that the head broke off. Used the Liquid Wrench, tap-tap, let it sit overnight and next day unscrewed the bolt by grabbing the teensy broken-off stub with pliers. THAT impressed me.
Worth a try, if you can find some.
You might also try GENTLY heating the variator part (not the shaft) with a propane torch, while prying against it. Heat might expand the hole open enough to get it loose.
When you get it straightened out, and re-assemble the variator onto the shaft, please be sure to tighten it PLENTY... I've used a large electric impact wrench each time I've taken mine off and on. I let it pound on the bolt for several seconds when tightening, and it usually takes about the same amount of impact to loosen it again. You REALLY don't want a repeat-performance of the problem you're having now.
As "Red Green" says: "We're pullin' for ya... We're all in this together..."
