Using washers to tension the springs would still increase strain on the clutch cable. It is more or less the same as installing stronger springs but a cheaper solution. Using Kevlar friction plates with the soft OEM springs wouldn't change the tension on the cable and should allow for better grip while also allowing the clutch to engage smoothly.

My bike (my subconscious) would think I was a jerk! The idea is to make her soft and smooth but able to grip like a vise.

In VW Beetles, Gene Berg sold a device that gave a slight cushion to the engagement of a racing clutch to soften the blow. Not just to the crankshaft, but the relatively soft magnesium alloy case as well. You see, the crank is forged, rather than cast, so that it can flex without breaking. A certain amount of flex is required, because of the flexibility of the case. A cast crankshaft would break from the flexing; indeed, even some forged ones do from time to time. It is rare, and the only one I have knowlege of personally, the engine still ran, although with a wierd noise and rhythm. But it ran!! Upon teardown, lo and behold: broken crank!

It lasted 23k and won't have the problems of an aftermarket clutch. A simple boost for the springs is one spark plug washer under each spring. No more, just one. Heavy springs are a strain on the clutch cable and make for jerky starts. Nasty clutches are for racers, not street bikes. They get old fast. Hard riding makes for grooves worn on the clutch basket, which in turn makes for a less than smooth operation. Do what you want, I just don't care for aftermarket clutches. Put enough in bikes in my time... Proper adjustment makes for long life on the OEM.

Would it be better to keep the stock plates and go with some heavier springs? I really want this thing to stick in the high RPM range mind you... Reading reviews on the Barnett stuff... doesn't look good...

I do a lot of sport riding on CA-2 with my hawk and it is time for a new clutch. It still has the stocker with about 23k on it. It is slipping too much and I know it is just the clutch not the oil I am using... time for a new one. Looking for the best of the best regardless of price. I am in love with this bike and it deserves nothing less! Any suggestions? All I seem to find are those Barnett clutch kits... are they any good? Once I get the parts I can document the rebuild in case any of you should want to do the same. :D Thank you very much!
