i've riden it for more then 100 miles, but performance is still poor. Max speed is around 20 mph, if im riding it against wint it barely moves. Will performance improve later or i have to do something?
 
You need to re-jet the carb, they're jetted too rich from the factory. If you have an NT carb, try playing with the needle height, they usually will run better with the clip raised to the top notch. For WOT the only fix is to install a leaner jet, (#70 is stock) depending on altitude (higher = leaner) a #64 should get you close. If running a CNS carb, remove and practice your best overhand fastball, then repalce with a better carb.
 
what he said, plus look for oil leaks near a bad gasket somewhere on motor

Lowering the float SLIGHTLY could be a help also.
Mine does 35mph+ with no mods you couldn't do with handtools and sandpaper.

ok these engines are terible for eating crank seals so definatly worth a check if it seems realy gutless but all gaskets are good !


a tuned carb allways helps
