You'll be needing new plates then.

It'll probably be just the frictions and springs that need replacing, but you will need to check the steels to see how bad they are. If it's been slipping for a while they tend to blue up and go a funny shape.

When you do replace parts, it's best top go for an extra thick steel plate instead of the one thin plate that Honda saw fit to put in there. this helps preload the springs a tad and beefs up the clutch pack. Stronger springs are also an option. they don't give finger ache, but just strong enough to keep things gripping for a while longer.

If you're paranoid about the jingle jangle of the cry clutch then you can always fit the rubber damped plates at both the front and raer of the pack. Quietens things up just enough to stop too many silly questions at the traffic lights. Pointless if you ask me, but some people do actually think that the clutch rattle is a little annoying.

Holy thread bump Batman!!

My 28s dry clutch is slipping badly now. Been doing it a bit now and again but it has got worse in the last few rides.

What bits do I need? What Matt said above?

A list would help as I don't have a clue what needs replacing, obviously I will get part numbers etc.

Cheers

Bully

Bloody hell, you two are right 28 bullies!! Sad Very Happy

Cheers for the advice, so I need clutch kit, spring kit and thick plate?

What oil seal?

As it is looking likely that I will be dropping my heap off to Stephen in October, should I just order the bits and let him do it? Stephen is this feasible?

Once I start poking around all manner of things could go wrong.

Don't talk about things going wrong when poking around... Steve's ended up with two kids that way! Laughing

Good way to go about trying to sell stuff eh... give you Marketplace links and then insult your bike! Laughing

Still, we know you have a sense of humour Bully, don't we Steve?...

Crying or Very sad

Was thinking that I could swap the motor for a 50cc twist and go to make it easier to ride, no one will notice the performance difference!!

Stephen what do you think about doing the clutch when I drop it off. We are going to book the boat in a few days for Oct half term, drop the heap to you and then off to Wales. If I don't get raped by the Welsh then I will pick it up 5-6 days later.

Or would it be prudent for me to do the clutch first so it works properly for the dyno? when I say me, I mean the dealer here. Whatever I touch goes bad, I have a black finger of doom.

Go to PM if you like.
