thanks guys i will recheck the chain tonight.. also have another problem.. i was fooling around the carb last night. i felt like the bike was not receiving enough fuel so i think that my float wasn't placed right. after opening carb
and adjusting the floats/pins tried to start the engine it wounld't start.

Checked the spark plugs and it was soak with oil and gas. after awhile changed the spark plugs it started but am lossing rpm turned the air high
one turn rpm went from 900rpm to 3000rpm.. so i tried to make it exact on 2000rpm.

I test ride it and it felt that there is no power at all..(like choak was on or worst)

Note: i did not re-adjust the pri/sec jets.

What could be the problem?
