When I accelerate I get a clacking noise and my acceleration is not what it was when the scoot was new. I am sure my clutch pads are glazed and I need to rough them up. A buddy of mine has an impact wrench so getting the nut holding the bell on should not be a problem I don't think. So before I attempt to do this I wanted to ask a couple of questions:
1) If all I want to do is rough up the clutch pads then is only the removal of the clutch bell required? It's not necessary to remove the belt in other words.
2) What grit sandpaper is best to use?
3) When I reinstall the clutch bell nut should I use lock tight and is there a torque value for this nut?
If there is anything else I need to know please share those experiences with me.........thanks, Dave

If your going to us an Impact Wrench just take the bell off , YOU DO NOT have to take the belt off and you can unglaze the pads without taking anything else off JUST THE BELL. You use any sandpaper you may have laying around, all your doing is going over the pads LIGHTLY to take the glaze off. Then when putting the nut back on you tighten it up with your hand and then give it 3 1 second raps with the impact wrench to tighten and you should be good to go.

I live in New Orleans and it's Mardi Gras time and scooting down to the parade is the "cats meow "! But when leaving the parade that's when you encounter traffic and when my slipping clutch clacking is most prevalent and it's driving me nuts! When I gun it no problem. So tomorrow I plan to pull the CVT cover and the bell to hit the pads with some sandpaper. What should I clean the inside of the bell with. I've seen roach spray......something about borax? Also I've heard brake cleaner......I've also seen some post about using Emory paper on the inside of the bell after cleaning. Need help on what the best route would be........and responses tonight and tomorrow morning are greatly appreciated as I plan to do this tomorrow......thanks......Dave

Brake cleaner if you have it, carb cleaner anything just to get any oily film that may be on the inside of the bell really, No biggy and don't grab the inside with your hands that leaves oily film from your fingers.

Got it......thanks!

OK......all done and what a difference that made! Take off is smooth as silk!

[alleyoop]

Fantastic!! It is very common on the heavier scoots for the pads to glaze mostly due to taking of slow and that is when they slip and glaze up. I usually tell the guys give it some juice to get it up to speed then you can back off once the dead weight has moved it helps, the pads will not glaze up so quickly and start shattering taking off.

Ya know, I also think I notice at least a little difference as temperature varies. Seems like first thing in the morning it's smoother than later in the day, or later in the ride when the tranny has heated up a tad. Does that make any sense?

[alleyoop]

makes sense since heat makes thing expand so they maybe the stud that the pads rotate on expand and hang a bit and require just a tad more rpms to throw out the pads, maybe that is what you notice or feel.
