Clutch Springs

MLC Racing · 10-Jun-2009, 00:45

I would like to use stronger clutch springs in my 620 monster DD bike. It has the semi-slipper clutch thingy.
Is there a ducati spring from another model that I could use in a straight swap?

Hi Dave, me again.

We had that clutch in my bike originally but found it to slip. We put extra washers in to increase the tension on the springs but it then started slipping again so we tried to fit another washer in and ended up putting too much tension on and broke the clutch basket. So we ended up borrowing a clutch from Skids at Snetterton last year to get us through the meeting.

In the end we fitted an older non-slipper clutch and all was good.

You have all got too much power.

I've done a season and a bit on my APTC clutch and it's only just started to grab on take off (see Snet race 2....), but no slipping.

Maybe it's because once I've got off the line I never pull the lever until the cooldown lap (or the graveltrap)??

I can't master the "slight slip to vary corner speed" technique, but maybe it only becomes necessary when you're fast?

So that'll be a no then!?

Is there room for an extra plate?

I remember using 996 ones in my first DD 620 - I think???? + an extra plate too...

You remember right.

I've put 996 springs in #34 to cure a bit of slip.

dave quite honestly the std clutch with an extra plate in it and 916 type srpings is the way to go unless you put a full slipper in it. the aptc is a bit soft on launch and doesnt grip well and can lose you time at the start.
when we had to swap bikes last year between races after a big crash in race 1, clint went from 1st row to 13th at redgate purely down to the launch of the aptc clutch on the 2nd bike
