Question about Gas Gas Motorcycles
It has me new top end, piston, ring, small end bearing and honed the barrel. I have put a brand new vhst26bs carby just like factory supplied and still has made no difference.
Is the machine a two stroke? Because if it is a blocked exhaust (full of carbon deposits) will cause exactly this symptom. The best way to clean it is to stand it on its end and fill it with oven cleaner and leave it for a day. In the old days it was just a case of heating the exhaust with a blow lamp and tapping the pipe gently to loosen the deposits

Check for a worn Crankshaft bearing and seal on the left side under the flywheel. Remove flywheel cover and try to move flywheel up and down by hand. If there is ANY moved or play then replace the BEARING and SEAL. If no movement then spray WD40 onto crankshaft seal while running and if bike speeds up replace seal. Good luck!

Remove the slide from the throat of the carb, move the clip on the jet needle one notch lower. This will richen the low end fuel/air mix. - - - Simple, quick, and free.

SOURCE: pw 50,
cover up the drilled holes this can cause problems, why was a new carb fitted? did the shop have it running?
not likely rings .
check carb for flooding and correct jet sizes.
check safety kill\start\run switch for shorts.
