Align and adjust your motor's chain!

Spec. of the 2 bolts are: 

• M7 * 35 mm (or longer than 30 mm)
• M5 * 8 mm (or longer than 5 mm)

Alternatively, metal bolts can also be used with this tool. 

(However, I recommend using metal bolts and straight rod if possible.)

I hope it helps you!

Sometimes, the rod may be not straight after pulling off the plate. So I made another version that should be straighter than the old one. 

Use a glue one the two halves of the rods and then attach the two caps, you will get a much straighter one!
