Could someone please tell me if this is correct and which model 350 what oversize do you get and how much needs to be machined from the top.
Thanks Chris

68+ CB350 twin. 64mm gives you 812. Get 350 +1mm over for 836. As far as the machining goes you may want to PM Big Jay at APE as that's what they made their first kits from. It'd be a lot simpler finding a kit ready to go.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)
