How do I put the timing chain on the cog for a 50cc scooter
Btw the cog is on the new crank shaft it put on
For some reason the chain doesn't come on

What do you mean? Is the cam chain on the crank or can't you fit it to the crank?

He can't get the chain around the sprocket/cog that's mounted in the crank, I thought there was a side cover that you could unbolt to get to the sprocket similar to a Chinese pit bike I used to have,

Yeah I can't get it on the crank do u have any tips please?

youtube it, I find the answer there sometimes

Finally I done it!!! I ended up splitting the engine and redoing it

Told you

Still I've got till this weekend to get it done or I have to scrap it says my parents

Haha you best hurry up then

Yeah shouldn't take that long I gota put all head and new pistions rings and pistion head on and put variator on and belt and kick and flywheel cover then fit it... Do you know how to put the belt on because I don't know how to fit belt in clutch housing because it closed
