Please refresh my memory on the theory. For example a 50 degree compared to 44 degree. which shifts out faster. Also the faster it shifts out, then the slower it backshifts? If I take the 50 from my 99FZ500 and put it on my 98 SL that has a 44, do you think it can pull the 50. ( assuming 50 shifts out faster). My son who only weighs 130lbs drives the SL and I think there some left on the table with the factory settings. Can I just move one driven clutch to the other. Ie I think I have to use the same spring with the same helix.
Where I sled: ditches, fields, and river and lake ice!!
you could put the 50 in with no problems other than maybe over reving the engine. it is one concern, being i have no idea about your clutching situation. the higher the angle the quicker the up shift but the slower the back shift. so a 50 in place of a 44 will give you a faster upshift but a slower back shift than the 44 gives you now. it really depends on what you want to achieve by the change in parts. you can change springs and helixes, they aren't "matched" or something like that. my opinion is to change the 44 to a 50/46 or so, and play with secondary spring preload to get the best results. that way you will get the best of both helixes, but that is with all other clutch parts being unchanged.
