Answer 1

Try a new plug, turn your air s***w from lightly seeded to 2 turns out...Always mix your fuel for that bike at 4oz oil to 1 gal fuel....How's your air filter.??

There are so many things that it could be without seeing the bike run..

Most people don't re-pack there silencer (real important) and never take it off....

!st...Go get a new plug

2nd..Air s***w..2 turns out

3rd.. air filter...clean and oiled

4th..gas mixed right..

5th..drain the fuel out of the bottom of the carb...see if there is any water...

It could be low compression and you might need new rings..

Answer 2

If you just kick it and go then whack the throttle your rpms aren't high enough if its after awhile then it could be a lot of things it sounds like your spark plug might be fouled or too old mine did the same thing because I fouled out my spark plug by having too rich fuel/oil ratio and those two things would help the performance I don't know if they would effect your problem directly
