2.)loaded 8dn 20's with w/w/w/ spring and 54/46 helix with green sec spring is for drag racing and wide open lake type riding, its very aggressive upshift will NOT be something you want in tight woods trails, its backshift is about comaprable to the stock helix with only 1 degree shallower. Its about as aggressive as you can be with the 8dn20 weights.
this is the set up I would like to run but in a 98 srx stock but with bender muffler, stock track with 96 woodys carbides. What helix should I run looks like ulmer racing on ebay have 51/47, 53/47, 53/43, 50/42, 51/45 available. im new to this and just want to amke sure everything will match up. Thanks
