Got about 10k km's so far. Runs great.
I went with the Barnett scorpion....a mix of the heaviest and second heaviest springs.
No slippage at all, very heavy clutch lever though.
Cheers.

thats good to hear!
I've been riding Harleys since late 70's & drag racing them ( street class & modified Bike class & when we had it SE Harleys. have had a few clutch but never tried the scorpion. have had Bandit Machine works super clutch, S&S clutch, I'll try & see how the stock clutch minus spring plate & with one stock friction & two steels goes first. then if not holding try an AIM pressure plate as think I can get one to work & keep light clutch pull, I don't mind some slip in 5th just not too much.
was interesting with my twin cam Dyna as stock clutch with SE diaphragm spring, started to slip in fith gear 5 speed box, so at 1/4 mile drags I just held it in 4th gear through speed traps. then latter spent $$ on an S&S clutch , was a very good clutch too no slip. but at drags no improvement at all no quicker in 1/4 mile no faster, so this time a bit wiser.
