Default Re: Bicycle sprocket + 415 chain?

Today I visited a friend who has a machine shop
I dissasembled the stock 44t rear sprocket and used it as a template
Enlarged the center hole and drilled 9 holes in the 36t bicycle sprocket
Cut 4 chain links
Reinstalled everything
Tried it slow at first, and as I understood it works perfectly I gave it more gas
My motorized bicycle rides at low revs at a perfect cruise speed
No more engine vibration
I highly recommend this mod, I am 220 pounds and it has almost the same low end
