ReplyDeleteI will be using a 280 back tire. iwill also be using a exile chopper sprocket brake. If you make a sprocket brake I will purchase one from you. would it be possible to run chain side by side? I would like to have the belt and chain from the motor to the jack shaft. I hope you can shed some light on this. You have the best descriotion of a jack shaft I have ever seen. if you can i would appreciate it.
ReplyDeletewant to use a belt but I would like the cleaner look if possible
Thank Robert
I would like to tell you guys that what a web site you have going. Building bikes since the seventies. Wanted to build a jack shaft, after all these years when they said it couldnt be done without offsetting the motor which a third grader knows that something is going to be lopsided. Is ther any way that you could put the belt and sprocket on the same side? I am using a 18-5/12 280, I have twelve inches between the inside rails of the rear section, thats inside to inside. Thanks again for you expertice. Robert

I started on my 73 Bonnie 750 way back in 1976..was gone for 3decades and am looking to come into the new style fatrear tire and longer stretch on my corbin gentry wishbone frame that has a Fury dualspring girder 16over.I knew the only way to get wide in the rear was with fabing a jackshaft to offset clearence.You have a very clean fab but was wondering about being able to adjust the tension from drive sproket on engine to jackshaft 2nd drive.Also what lubes the shaft and/or bearings?
