Decreasing power for newer 500 owners

<< < (5/5)

52mm carb :-D

How come nobody suggested urinating in the fuel tank yet ? Probably worth about -15 hp, but the stench might be an issue to the riders behind ya'

be careful with the restrictor in the silencer. most exhaust restrictors will be at the front flange. restricting exhaust out the end will hold heat in the pipe changing its tuning for higher RPM's. and if you hold in to much heat pistons will start to melt.

Decreasing power for new owners!!! Bunch of pussies!!!! Thats why you buy a 500 2 stroke is for the insane power hit and acceleration. If you dont like it then get on a 4 stroke problem solved leave the 500's for the people who like the power :evil:

My KX500 was my first ever dirtbike. I didn't really need a power reducer. Fear of death handled most of it...

If one really wanted to make a limiter of some sort though, why not put something like cable insulation etc... around the bare throttle cable inside the carburetor so it stops the slide from opening beyond a certain point? Need a lil more speed? Unscrew the slide cap off, trim off some material, there you go.
