TY175 clutch question

Postby Bigem » Fri Jun 04, 2010 9:08 pm

I am hopind somebody has had this problem before.

My TY175C has a very light clutch, its almost one finger light, but it has very little take-up, no more than an inch of lever travel.
It doesn't slip at all but it makes it difficult to balance the bike in tight turns because the take up is so marginal/abrupt.

I was thinking new plates might be the answer but that does not make sense, it works fine, it just isn't very forgiving!!

Would lengthening the clutch arm address the problem

Any of you learn-ed trials guru's struck this before?

Any help would be much appreciated, Andrew

Is it just the narrow engagement or does it also self-engage once it starts to engage?
If it is just narrow engagement yes a longer arm will make the range wider, but it will still self-engage if it is doing it already. The engagement distance on a standard TY175 clutch is pretty much ideal so I suspect there might be another problem.

Thanks for the reply David.

I dont think its self engaging.

When I stripped the motor down I was a bit surprised at how good the clutch basket was, very little wear and the plates all measured up within spec.

Its the narrow engagement that's catching me out I think.

I fitted the standard length levers back on it, maybe they are causing some of the problem?

You have probably done this already but if not, have a look at the cam that pushes on the clutch pushrod. Sometimes pitting or a dimple develops in the surface and that can make engagement happen quicker.

Will do mate.

I can see where that could be an issue and sharpen up the engagement if its worn/changed shape?

Thanks.

Andrew
