so i wanted to start from scratch with clutching. today, i have stock primary spring, loaded 8dn-20's, and totally stock secondary.
with 80 wrap on the secondary, if i was running along and punched it, the tach went to 8800-8850 and settled in around 8600. turned down the wrap to 70. punched it, rpm went to 8600, fell to 8500, and held 8500 for a bit, then rpms started to drop to 8100.... i am not sure why this is? could only get about 97 mph out of it 20* day on smooth groomed trail which had set up...clutches were pretty cool, no belt slip
with a stock set-up, the pull felt quite a bit weaker than with my 52-46 micro belmont helix with 80 wrap, but i could only pull 8100 rpms with that (but ran 105-106 on gps)
tomorrow, i am going to go out with my 52-46 again, and try green spring at 70 wrap and see what happens with rpm. with this helix, midrange pull is alot more.
i am still confused why my rpms wanted to drop with my stock helix though, at some points with 80 wrap on it and the loaded 8dn-20's, say from 20 mph and i punched it, i would see 9000 rpms, but it still settled at 8600, then slowly fell to 8100-8200, very confused...again, clutches pretty cool...
is the 1gram of added weight in the midrange profile of the weight enough to pull down top end rpm after holding it WOT for over 3/4 of a mile?
help?
