My only obstacle is finding a belt that fits. I believe stock is 113.5" and I have a 116.25" belt on order, and I'm hoping that fits. Belts that large and with that many ribs are hard to come by. Even the one I did manage to find was only 7 rib.
that's a large pulley, but I do not think your getting the danger zone with the clutch slipping cause the let pulley is 185mm... but you are gonna be pushing quiet a high psi... higher than anyone I know... for these engines... please let us know of your results...
