After you properly install the ACCT, you should check the valve clearances. Do you have a manual for your bike? Do you know where the alignment mark for the cam sprocket is located on the cylinder head? Please post some closeup photographs of the cam sprocket and the cylinder head.

Spud has given you excellent guidance, as usual.
I'll add that the hash marks on the cam gear line up with the valve cover to head line, as you suspected. With the tensioner in place and properly adjusted, the hash markes should be in line with the valve cover gasket, and the T line should be visible through the inspection hole. It is possible that the cam chain jumped a tooth when the tensioner went south, so it should be carefully checked.

Everythings re-installed with new tensioner spring, piston at TDC, cam sprocket dot alligning with V notch on head (as pictured), flywheel mark visible through window (also pictured) and engine rotates with kik starter.
I now have to readup on checking the valve clearances. I dont have a torque wrench to get into the head for this so it may be a little while till my next post. Thanks for the help so far. |

You don't need a torque wrench to adjust the valve lash. Follow the procedure in the threads I listed, and you will do well.

PS the pitbike frame has year 2000 so this zongshen 250cc engine is probably 2000.
