Anyone familiar with CVtech clutches?

[Laundryboy]

I have a CVtech powerblock 50 that I need to change the weights in. From what I can research on the internet, it looks like it can be done without pulling the clutch and no special tools are necessary, does anyone know for sure?
Thanks Guys!

I've got a CVtech on my quad and it's easy to change the weights. I can just loosen the large nut on the outside of the clutch. Just under the metal cover are the weights. On my clutch the weights are incapsulated in a plastic block that slides and acts like a fly weight. From what I've found on the interweb, it looks like yours is the same style. If you want to add weight, you'll need to buy larger weights (metal disk in the plastic block), if you want lighter weights, I just drill the disks with a drill bit and weigh them so I can match them.
