All you need is an 11:1 big bore kit, an agressive Webb Cam, FCR 41mm carb and some stiffer valve springs and you're set.

So tell me something... honestly, are you a believer in the exhaust system.
Does it truly add a lot of performance?....
Or is it just a way of reeling in us old 2 stroke guys with the expansion chamber?

Has that airbox lid ever let any mud or water in?
I'm thinking you are in the desert where this is a non issue?

I have been thinking about making the switch to UNI.
I'm not sure I trust this K&N they put in there.
