The 3.5 and 4" belt setups are running about $1500 and probably not worth
it for what we're talking about. These belts are for engines that run
over 100 BHP peak and the riders of these bikes can be very abusive when
doing burnouts and drag racing.

Humm, I saw some brand new 3" with 2 pulleys and belt for less than 500
bucks, but they were set up for installing the one pulley on a clutch, so an
adapter would probably have to be made for that one.

If they are available on Ebay for less, that would be what I would consider
reasonable. 500 bucks isn't too far out of reach for most non 3rd world
country resident, either.
