Variator Notching

[Shaka]

It was a pain, but I think much of that was the learning curve as well!  Really all that I needed was 3 base gaskets.  I'm still running 2 and 2 top and bottom.  Went out today in search of metal, still no luck.  I did find some steel that was the right thickness, but I'll keep looking for aluminum just for ease of fabricating.

I was hoping you found some already! I'll resume the search as well.

Thanks bro!

hey Shaka, I have just tried the 5 gram rollers in my scoot but it was no good, engine screaming for bugger all, I have not yet got the engine right. The belt on my scoot is  Kymco 23100 KCX9000 Bando, I believe that is the standard one. When I took the 5 gram rollers out, the radial lines I put on the variator were mostly gone except for a little over 2mm, so the 5 gram weights wont close it fully. I have now got the 6 gram weights in (roller), see how that goes.

I believe that is the stock belt.  If you are getting all but 2mm on the variator face the 5g were probably closing it all the way.  They may not have had enough weight behind them to hold the belt tight though.  5g sounds very light to me though.  I know on mine I have tried 6g rollers and it just screams!  Right not I'm running 8.5g.  Before I did the reduction gears I was running 9g.  You most certainly need to go heavier!  I actually had good results popping my sliders in the drill press and boring them out.  That's how I went from 9 to 8.5g.

The variator came with 8.5gram rollers, when I put in the 7s I liked that a little better, I think 7s are the ones It didnt take long for the rollers to get flat spots on them.

Ive been running 5.5's from the jump!

[Shaka]

Were they low quality rollers?  Once you find the correct weight, I'd go for some sliders!

[sidthesloth]

Mister, you talked me in to it.

[Shaka]

They really do work!  They wear very minimally also!

now r u sure that var isnt oem sid?? you sure its different?? oem uses 8.5 rollers..surely its way different..the only springs he has says fits peugot?,stricker?(but they look the xame as mine ) gonna try whole new spring setup...sid,im running 7.5 at the moment..have sum carbon 7s to use, better for corners,7.5 better on top..

[thebatman]

 ...wonder if that var that sid has would actually help my setup or not??.. good day i can hit 52, avg.47mph, of course downhill i can bury it..lmao

Ive been running 5.5's from the jump!

..i preached on them..5.5s for so long...

[sidthesloth]

I think I could get used to the 6 but the 5 were definately no good. When I get used to these and get the engine sorted I may even try the  5.5.

The whole end result depends on the overall set-up. The 5's may not do it for yours. The idea is getting into the rpm range of the engine using the cvt tuning to make it stay there.
