My Winter Rebuild

[FoxMxRiders]

I wan to rebuild my engine this winter.There is my current mods :

Uni filter
White Brother R4 Slip-on
Dynojet kit
Pilot Jet #42

I will open my box next summer because I will ride this winter and don't want snow in my airbox.

Want I have thinking to have a good and reliable motor.

Je 416 10.8:1
Splash N Dirt Mx Cam
Rockers HD
Springs HD
Crf450 Timing Chain
Cometic Gasket

How reliable and how can't compare the power I will gain with this setup?

thanks
