ME TOO !!!!!!

2000 Scrambler 2x4
Wisco 20 over piston
VForce Delta Reeds
Reed Spacer
Clutch Kit
HPD Pipe
Stock Muffler(quite)
Porting(did myself)
Dirt Devils(rear)
Stock Oil injection(more weight, but better!)
(the stocker varies the oil from 200:1 - 16:1)
This saves plugs and parts at high revs. Only remove injector if you race or like to mix.

Must have forgotten something...

 

It looks like a stocker, except for the dash, the block off on the front hood, the rear rack and the missing warning decals.
This thing's a "sleeper", it looks bone stock, but runs like a guided missle.
That's the fun, blowing someone into the weeds with a stock looking quad.
I've been looking at the photos of some of the other guys 400's,( Jerry, Mike, Jack, Quadfather, etc. and all the others I forgot to mention ) with floorboards and mud flaps removed, modified PVT intakes, etc. and they're giving me ideas, but we'll wait and see.

 

Xplor,

How does that FMF Turbine Core muffler sound? I am considering buying one to go on a RCR Stage 1 kit. I hope it is not too much louder then stock, but I bet it flows much better and weights less too. Thanks.

 

It is beautiful, shiny and weighs in at about half of the stock one. So far, sound wise, she is running at about 0.00 decibles...No, seriously though, I am still waiting on my cylinder and carb from HPD so I have not tried it yet. It shouldn't be that much louder since it is forestry approved. I will let you know though.
