So guys i have a 3" BDL fitted to my Cycle and the starter often doesnt engage, if i rock the cycle back n forward in gear it then engages. I'm led to believe i require a Jack Shaft that will eliminate this issue also i'm thinking of fitting a front guard to the open primary as it does like to grab my boot now and again nothing drastic but hey. My last question is does a 3" open primary put to much strain on the crank
