I had an XS 650 Yamaha twin like a Norton and they were bulkier up top

Response to C1AE rods

than any FE rod but a Lemans, 7000 rpm Nascar rod. Tiny jounals and you had to break the crank to change the roller bearings, and the topend of them were the same width as the bottom end which had roller bearings around the pins.

You could actually split the crank hand get a Megacycle cam and move one side 90° to make a 270°/90° firing order instead of 360°, it got rid of a lot of vibration. Any 360° twin would dance on the centerstand if you vevved it up they vibrated so bad...
