it does
Motorcycle Mechanic: kwiggins29059, Motorcycle Mechanic replied 11 months ago

Thanks, ***** ***** will need to do is start the chain on the crank pulley pull it tight and put it on the cam while lined up by holding the cam then run the chain over to the tensioner side then apply the tensioner spring.

A lot of times there's two flats on the cams where you can put a wrench to hold it. If not you may need to use a small pipe wrench.

ok ive tried that it still the same the chain wont fit if both the sproket and the t is align its always advance by one tooth so the ,ark never align
Motorcycle Mechanic: kwiggins29059, Motorcycle Mechanic replied 11 months ago

If it's advancing when the tensioner is applied you need to align it one tooth backwards.

Ask Your Own Motorcycle Question
Customer reply replied 11 months ago
no its the original chain
Motorcycle Mechanic: kwiggins29059, Motorcycle Mechanic replied 10 months ago

Thanks, ***** ***** chain wear is the biggest issue here. You should have immediate movement when turning the crank back to the T mark.
