I have a 2010 M8 PG Turbo My set up from Vohk for trees riding is perfect. But at 1350' elevation it was over reving at 8470-8500 @ 7.5 lbs boost so I called one of our site recommended vendors and ordered two new clutches ,a primary with a billet spider and a new secondary both balanced. The first problem is the secondary shows up with a helix with no reverse notch, no biggie just more screwing around He sends me MDS weights all"set up" for the primary. The MDS weights bring my engagement from 38-3900 to 5300 and my rpm is now 8550. He sends me a new helix after telling me the best helix is a 36 and nothing else works as good, it's a 38? I'm thinking he's sending 40/36 like he said in a earlier conversation I get a 38. I try the 38 and have to say the stock cat 36 with no reverse notch pulled better but it seat of the pants and you know that can be wrong. So, right now all I want is around a 80-85 gram stock cat weight . I had 75 in it from Vohk. The MDS are 80 now but are farther off than I was with the 75 gram cat weights. I think the cat 36 with orange spring and shift assist works good. I ordered the new clutches because I had a spider break and the secondary bushing was toast. FYI any recommendations?
