Honda Spree and Elite 50 Forums

I have an 86 spree and was thinking about doing the pulley mod, but after a lot of reading it looks like i have to buy a slightly larger belt to avoid over running the engine. If I have to figure it out doing some math, i will. But if anyone had luck with a certain size let me know, and also where you bought it.

Dont bother with the pulley mod, same effect can be had by replacing the belt with a 1/2" automotive bet of the same or slightly shorter length than the stock one.
