Clutching Question (Peak RPM).

[BV1]

As per the below dyno of a stock Phazer:

How do I change my clutching to bring my peak RPM down from 12,100 (120 KM/hr) down to 11,300 or so.

I know I can change the rivets, but since I have never done so I was hoping someone could give me an idea what this involves.

Where do I get replacement rivets and are these the Canadian tire variety? Etc. Checking the weight of them and that kind of thing.

Thanks,

-Steve

tuneing rivets

you get the rivets from your local yamaha dealer. looking the teck secton at the top of the main page of this site for this and you will see that there are many differt wights of rivets avlable and there part numbers.

Thank you, I found and read that section.

When members say you need to "peen" them in, are they referring to a ball peen hammer or what?

I assume the weights remove easily before you work on them.

And lastly, to both the primary and secondary have weights and springs?

Sorry for the noob questions, new to clutching.

Thanks,

tuneing

both clutchs have springs of differt types only the primary has wights the secoundary has a helx with ramps you just punch out the rivets and peen the new ones in with a hamer and anvl so as they dont fall out and are not lose in the hole.
