Kawasaki KT250 question

Postby garensmith » Fri Oct 05, 2018 12:12 pm

Has anyone tried riding trials on a KT250 using only three of the six clutch springs?

I've done this with a couple of TY250 twinshocks and it works out very nicely. Before I try it on my KT, has anyone already tried it?

I've done it on a couple of TY250s too.
I also tried it on my KT (with newish plates) but it slipped too much. I then hunted around and found that a TY175 motor of unknown history had clutch springs that would fit and spring design theory told me that they should provide less pressure plate force than the KT springs and tried them. They worked a treat and are still in there.
The only weakness is that I don't know if they actually were TY175 springs, or something else that had been fitted to the TY175 motor before I got it. I may have written down the crucial dimensions of the springs I used in which case I will post them up here.

OK I looked in my log book and found that I used four TY175 springs in the KT clutch and that the clamping force is 75% of the clamping force of the six KT250 springs.
Sorry I didn't find the spring calcs or dimensions.
