89 DT125r Jetting and De - Carb

[B10Hazard]

I am planning on getting the full DEP or BIG ONE pipe and chamber for my dt. Does anybody know what would be a suitable jetting ?

Also how benificial is a De - Carb. I want to clean my current exhaust and silencer.
I have also been told and read about cleaning my powervalve.
Whats the best way to do this and how often should it be done on a 2 smoke. ( Not just the PV the whole thing )

Tharrrnk ya
