I recently bought parts from www.helixparts.com/usa and am very happy with their products.
I bought their complete new Clutch, Variator and CVT belt for $185 (it was on sale). The clutch plates are actually about 30% larger than the stock clutch and they look better made than the stock unit.
The variator comes with 21 gram rollers and it also looks much better than the stock variator.
The CVT belt came with this set, but can be bought for $30. The belt looks to be of a good quality too. _________________ 2006 Roketa 250cc Buggy
