I have a 98 600XT twin and would like to try a 46-42 bender helix. What wieght set up should i use in the primary? I would like a engagement RPM of approx. 4000 RPM and a shift at 7800 RPM. What twist should I use on the secondary? The sled has stock gearing (23/39) One layer of head gasket removed, reed spacers and I run a 1.25 ripsaw track. I wiegh 180 lbs. ride mostly groomed trail and lakes. Or would the stock helix (47degree) be better.
