This information was provided by 2strokd.
I had a homemade restrictor ring in that was very thin and only filing a little off the outer stop plate, now after filing the vari stop and the drive plates 2 times to take about a millimeter off(im guessing, probably more) i am running without a ring at all and it takes off great ;D. Digs hard, before it would roll out on a bit of a bog(not much), then rev(almost free rev), then grab and go. Now it just flat out goes, seems to hold "first gear" longer, and because there isnt as much material in the center of the vari it should push the belt higher because it can close more.
I finished mine up a little bit ago and had time for a short ride before a storm blew in. It helped allot man, i can take off great and my rpm,s are down at at cruising speeds and higher speeds. I couldnt top it out but i did hit 55@ 9,700. Thats about 600 or less rpm than before, and all for free, thats the best part
. I wish i remembered were i read about this because i would like to give credit were its do. I didnt come up with this idea on my own, i just read about it and did my own experimenting. I am happy with the results and plan on doing more soon. I want to get a spare vari first.
Just take it bit by bit to get the feel for how your beast is responding to it.
Here are a few pics to get the brain picture
The vari "drive" pulley before doing anything
The drive after a bit of filing
The vari "stop" pulley, or "fan pulley" after a bit of filing
Here you can see the fan pulley with the restrictor ring in the recessed spot for it and the drive boss, before i started the ring was flush with the vari face. When i got done the recessed area was about gone, and i think i could go more.
I put about 25 or miles on since i hit the vari with a file and i like it. I think i am going to take a bit more off the center of the vari and try working on the top a bit to hopefully get a few more mph out of it. Im going to "slope" the top end of the vari so when the belt gets up so far (past 3/4 of the way up) it will want to slide higher easier.
