15hp gx200 db30 drag gearing help

[Atsownz]

I just picked up a nr racing built gx200 dynoed at 15hp. Im running a draggin skin clutch with a 13t sprocket, and the stock 70t rear, along with 13" slick. I way 220lbs, and was wondering what would be good gearing for the 1/8th mile, and 1/4 mile.

There is no set gear setups. Its going to be trial and error. Start with what you have and then reduce you rear gear to get the best 1/8 mile and 1/4 mile. It also depends on where your HP and Torque is achieved at RPM wise. If you have a low RPM motor you are going to gear high (less teeth rear gear) and if you have a high rever it will be geared low (more teeth rear gear).
