Re: Slipper clutch
I have heard that they are, but, I've never heard of anyone in the racing world that has actually got one set up to work. I've had my clutch slipping on the power and yet it does not work as a slipper clutch. When you read this: http://homepage.ntlworld.com/webzxr/zxr750r/, that tells you how to 'tune' it to work, you'll understand why I said what I did and am not sure at all that they actually are a slipper clutch in the 400
As for backing it in, I would suggest that you've got a lot more to learn before you try doing that, you'll end up on your arrse for sure. But, brake very hard so that the rear tyre is hovering/sliding over the tarmac, then start turning the bike (as a matter of fact, doing that will show you how obviously you are countersteering
), the back will start coming around, then ease off the brakes to controll it. Or/and use some rear brake to get the same effect. Good Luck
, I would suggest trying it in an empty car park, and take some spare levers with you
Oh, and it'll be a lot more difficult doing it from 100+mph into a, say, 60mph corner and carry a decent corner speed, doing it all smoothly, and not come off
One final point, Why? you gain nothing, the only thing that it may help with is to make yourself wider going into a corner so that anyone behind you won't so easily be able to sail past you into the corner
, although I do admit it looks good

had an L engine (they were only fitted to L's) in an H2, and that worked so well that you couldn't bumpstart the bike at all, but it didnt slip under power one bit. The stock clutch in my L4 was ostensibly the same, but set so tight the back would chatter and lock all over the place.

Re: Slipper clutch
a slipper clutch prevents rear wheel lockups when you downshift to the next gear, it does this by allowing the plates to slip when off the throttle but not allowing when accelerating.

Re: Slipper clutch
Did you have to buy the thinner plates to set it up or is there an easier way - thinking of getting an L one for my H race bike.....

Hello mate - Have been busy racing as much as poss this year - all East fortunr events, Knockhill, and even managed a Croft - what a track!!!!zimm wrote:they do work, but need time consuming fiddling and the random factor..Ballsout Racing wrote:I have heard that they are, but, I've never heard of anyone in the racing world that has actually got one set up to work.

During all this managed to drop a valve ay East fortune, new engine purchased off fleebay, it has a slipper clutch , but i think the stack is too high for it to work as a slipper , do you know of anyone who can tell me the best height of stack of plates for racing?
