If you are handy with a drill or better yet have a drill press, you can drill yours stockers out like I did mine. I think I used a 5/8" drill bit, but don't qoute that. It was just slightly bigger than the hole in the roller. Drill it out and it will be really close to 17g each. It will make a tremendous difference. It was like I doubled my HP on my buggy. It wouldn't climb very well until I did this. I actually used a dremel on mine and took another 1/2g out of them, but did not think I should go any further and risk the structural integrity of the roller. When I disassembled the variator it had what looked like your standard molly grease in there. I completly cleaned it out and sprayed the rollers and variator with with lithium. I have been abusing mine for at least 3 months and they are still in great condition.
I just received some 15g sliders that I will be trying in the very near future.
I will try this...Thanks and let me know about the slider availability...
