I'm installing my 80cc on my mountain bike now. How tight should I tighten the sprocket bolts? I have a gut feeling that I should go tighter than it is said on these instructions:
Instruction Manual - Gas Powered Bicycle Engines, Motorized Fast Bicycles, Motor Gas Engine Bicycle, Bike Conversion Engine Kits, Motor Assisted Bike Engines 80cc and 49cc, Peddle Start Motorized Bicycle Engine and more!

What do you guys think?
~Thanks
