Replace GEBE treaded Belt Sprocket

[hawaiioutdoors]

Aloha All,

I've been messing around with the GEBE Tanaka 40cc mounted to on a full suspenion moutain bike.
Because the GEBE is limited by its Proprietary Belt... (You cant run fatter then 2.10 tire as it rubs on the belt and throws it off.. The engine has to be mounted 14.5 inches above the rear axle for proper tension...)
Ive had the GEBE kit for about 6 months, and went thru 3 belts. I want to switch to chain drive, and play with that awhile.
DOES ANYONE KNOW WHERE I CAN GET A DIRECT REPLACEMENT FOR THE GEBE BELT DRIVE SPROCKET. I NEED A THREADED CHAIN SPROCKET.
GEBE's Drive Belt sprocket threads on to the motor side. I am having trouble finding a chain sprocket that does the same thing. All have a center bore that locks on with an allen bolt..

Thank you.
