KTM DUKE 200 speed cut off.
This bike is currently using 39T rear sprocket. (standard is 42T). this vid clearly shows that there is a speed limiter of some kind. Although the rev limiter hasn't kicked in, the speed cut jumps in after 137kmh. Thanks to an anonymous friend for the Vid. P/S : speed kills. Don't try this at home. lol

How to adjust carburetor by Mandy Newcity
Keep factory settings in mind just in case u mess up ur air-fuel ratio, so via switching back to original settings u will be immune to errors, and listen/feel the rpms, and leave where they become constant, good luck
