Hi everyone,
I just bought an old Odyssey that was not running. I managed to get the engine running, but the clutch grenaded and took the crankshaft with it (no belt was on at the time). I bought a new 4 stroke 390cc motor to swap in ($100 brand new, could not go wrong!), and I was planning to convert it to a chain/sproket. While trying to figure out the optimal gear ratio, the first thing I had to do was check the reduction unit gear ratio. I put it on jack stands and turned the wheels to count the revolutions of the input shaft. Here were my (non-scientific) results:
For every 1 turn of the input shaft, the tires will spin approx. 9.25 times.
This seems backwards to me - I thought it was supposed to reduce it by 9.5, not increase it. Am I mistaken?
Thanks!
