420cc clutch recommendation

[shawnped]

max rpm is probably around 5500 right now
gearing for 6:1 - 5:1 and only aiming for a top speed of 75mph
stock with 15hp but will likely mod upwards of 25hp
wheel/tire combo is 26" diameter
this will not be used for racing, only cruising, so hard launches are not going to be a factor. a low stall/lock/engagement would be nice so once its locked it ideally wont slip.

for reliability on long rides is a multi-disk (3 or 4) recommended or could i get away with a noram star or 1600 type clutch?

I am more worried about heat and slipping on long rides than burning rubber.

thanks in advance

Do you have some pics of the bike or are you still building it?

there isnt much to look at right now; just a lot of parts in the garage. this is really the last piece of the puzzle i wanted to get dialed in before wrenching.
