Clutches and bells

[johnny248]

Couple of clutch upgrade questions.

I would be wrong to assume that a 2 shoe clutch would have harsher engagement than a 3 shoe clutch? Similar to say a disc clutch or 3 puck clutch in a car?

Next question. 107mm clutches. Are these larger than the original clutch? Do they fit the AF16 motors? Or does it require some sort of modification?

Adjustable clutches vs fixed clutches. How crutial is it to have an adjustable clutch vs one which is not adjustable?

Is there great benefit with and adjustable clutch like the Polini 3g or Stage 6 clutch? ( I mention these because it says you can adjust them without removing the clutch)

I'm guessing you can match the clutch engagement with your power band or setup where as the non-adjustable clutches are just set how they are. Will a non-adjustable clutch hurt performance on a modifed engine?

What expert level is require to be able to tune and adjust one of these clutches?

Bells-

People say good things about the Malossi Wing Bell. Stage 6 also has a vented bell. I'm assuming the idea here is cooling, just different ways of going about it. And then you have the Polini Evo and Malossi MHR which are open face design which again, probably for cooling as well as lighter weight?

We have talked about this a little bit before. I am leaning toward either the Polini or Stage6. The Evo2 combo you offer, is that the 3G clutch that we are talking about?

And with the S6, does that vented bell fit it?

I kinda think I like the S6 clutch a little better. It says it is very easy to adjust, and the weights seems like a cool idea. Plus, as much as this doesn't matter, I think it "looks" a little bit cooler lol
