I have a Apex 2008 LT90 Iam running a 780 16.5 30 with stock clutch and Herick front mod variator. I have been told to run a 787 17.1 30 belt. What additional mods do I need to do if any to make this setup complete?

MANY THANKS

Are you sure that is correct?? It should be 787 16 30 just put it on. It will make a big difference over the 780 16.5. JMO

We have no problems running the 780- 16.5- 30 with a stock clutching set-up. Tyler could run up front with this set-up at any of our local races with the exception of a few quads that are really modded......my 2 cents for what its worth

apex sold me that same belt 2 years ago with 2 shims ,and told me that it was the set up . it did not make a difference.

call Hetricks if you have their variator ,i know that they mod variators for a certain belt sizes, if not you may have problems with belt travel or slippage. jmho
