Dry Clutch

The early Sportster-style dry clutch set up is one of the best in motorcycling. It's design is basically still common on the XR750 race bikes. This clutch works great as long as you keep it dry. The plates are housed in a sealed clutch basket, the tranny mainshaft is hollow - and it's disengaged by a series of pushrods. Until very recently, many top fuel drag bikes still used this clutch. However, if it gets wet(and you're using Raybestos Dry Plates)you're screwed.
The K Model needed a refresher . . . it was wet and it had been 2 years since it was serviced. With the cover off, you can see the internals. The red springs are heavier Barnett springs - to help it hold under the massive torque of 40 horsepower ! The front compensating sprocket is about as vintage as you can get. It's in good shape - so I keep running it. Goth Girl gave me the Devil Doll sticky about 3 years ago.

Yes that is true that is the set up my pro drag bike is running on it.Even though i have not been able to run it lack of money its got so it takes so much money to race the poor man has no chance any more to even just have a little fun.Get to Charles city Iowa and get all the bikres to put $25.00 in me and the Noots might have a chance.
