Re: anyone having problems with jackshaft front bearing?
The heavy duty freewheel will solve your problem. Some people need it, some don't. I guess it depends on how easy your motor starts and how hard you kick it over.
My guess is that SBP sell the White Industries freewheel at pretty near cost. They are a really good value. Every other time I have seen a White Freewheel for sale it is $100 or more.
