i have been playing around with my new supertrapp on my mildly built 200x. white bros trail cam 10.25 piston and 26ml xr carb. so far i have had the best luck with a 130 main jet and 5 disc's in the silencer. i went up to a 132 and 4 disc's, and the power fell off. when the rain quits i will remove one more disc and see what happens. may be just not enough back pressure for a mild engine.

so i just got to wondering what what jetting and disc combos every one else is running and with what engine mods.

:wonderingwow ive been going about this the wrong way. i thought removing the disc's reduced the back pressure. slightly embarassed
