honda trx450r ?

[5.4 speedster]

I have a 06 trx 450r with a 480 kit and your exhaust system. Id like to run the open end cap on it and I am wondering how many plates I should run?

The open end cap is equal to 9-10 discs, so remove that many, go with the open cap and go ride!

Ok so how many should have been on from the start? I am sorry but this is all new to me as I just bought the quad and the exhaust was on there already

Here's a copy of the instructions.

With the big bore kit? I would go by how it runs?
