Default Belt Sizing when swapping pullies.

I remember picking up a smaller belt when swapping down to a 3.4" on my Series 2

Was thinking it might be a good exercise and valuable information if we could list up the correct belt size and pulley sizes on each series of motor to be put into Techinfo for future use.

Please try to keep all discussion to zero. It is expected we will have a few areas that have more than one possibilit, let'* list them up and discuss differences in another thread.

Thanks

3.4" will need a gatorback 715 belt. i dont know the specific length.

the idea of runnin the stock belt and a larger tensioner wont work though. belt was hitting.

So a 715 belt will do either 3.4 or 3.5.

For Gatorback belts and most other belts... 715 = 71.5"

For comparison, a S2 stock belt with a 3.8 pully takes a 725 belt.

C'mon folks...

Let'* list the belt sized you used for your pulley sizes... Surely we have more than S2 owners on the site.
