Ain't gotta clue how removing the exhaust will cure it or cause it!

Don’t shoot the messenger I just asked the lads up the pub who race 2 strokes

Hope you get to the bottom of this problem soon Al

if all your carb settings are ok and you have no air leaks on the inlet i would take a look at the ignition timing is it over advanced? is it retarding as it should when you drop the engine revs? is the power valve opperating as it should do?.as said before iam no two stroke expert but have owned a few in the past,can remember having to remove the exhaust on one due to it being completely clogged with coke although the bike did still start and tickover ok it was as flat as a pancake in the power department,but what a difference when the exhaust had been decoked and the engine could breath.http://justkdx.dirtrider.net/kips.html. you may find some usefull info on this site.

Well bike is sorted ;D
Looked in the Haynes manual apparently the throttle cable is in 3 parts and splits at a junction top part to twist grip, one from junction to carb and the other to the autolube which syncs with the lower cable for carb.
who everhad the bike before hadnt adjusted the lower carb cable properly so it had no free play so keeping cable or rather the slide up by about 8mm so thats why it wouldnt go below 4-6krpm.
though the slide sounded to be hitting the bottom of carb it wasnt, only the idle speed screw. sussed it when i took air cleaner cover off looked down the air intake to carb and saw it at least the carb had a good clean out 3 times lol
