I read something where someone put a crf50 or some other sprocket directly on the atc70 axle to get rid of the dampener setup. Anyone do this or know what it takes?

I would have to think it would be quite a lot of fab work to do so, what would be the reason to do away with the dampener setup?

Thinking that upgrading to a 140cc + might be too much stress for the dampener setup?

I would suggest that you reach out to members SS LS1 and John jr to see how they addressed the situation. If you look at both of their profiles, they have put together quite a few big bore ATC70's and would probably be able to answer your question

The ZB50, ATC70 and CT70 all use the same rear cush drive hub set up and the same rear sprockets. I have never heard of any problems and some have upgraded to 190cc motors. If your concerned I'd replace the rubber bushing in the hub. 20-30 year old rubber dries up over time. That's my 2 cents...

I would think the big motor is more reason that you NEED the cushion. Something is going to take a real beating there...the rubber, or...something else.

I run the cushion rubbers in my R55 ATC 70 with the Daytona 190. They are fine. They will wear out in time and abuse. Gordon Spangler now sells the sprocket hub to fit the ATC 70's that will let you run the CRF sprockets.
