Baja jackshaft 35 pitch sprocket
I ran into the same issue when I used a Baja jackshaft on the 212 Predator I installed on my DB30. I also needed a 35 pitch drive sprocket to match the rear sprocket on the DB30. The shaft on the Baja jackshaft is metric and I couldn't find any metric bore sprockets for 35 pitch chain. I machined a new shaft that allowed me to mate the metric jackshaft driven sprocket with a 3/4 bore 35 pitch drive sprocket. The setup worked so well I picked up another Baja jackshaft from another forum member to use on a future build. If you pick up a Baja jackshaft and need my help to duplicate the setup I used let me know.
