Clutch conversion.Thinking about the power etc and what to do I had a few concerns. My idea is to get it to 800cc with a CR of 10.5:1 and make a real torque monster. Hopefully achieving 60hp in the process. So a standard or even uprated A10 clutch will not do!
A Suzuki GS or GT500 is an easy swap but both of these are about 50hp in stock form and I know from past playing that the GT550 clutch is not capable of much more than 60hp and with nowhere near the torque of an 800cc 4 stroke!! So I cancelled these out.
I considered a Commando conversion but then realized I had a stripped Yamaha FZR750 engine in my stores. And the clutch on this is the same as that on the FZ1000, both of which out power my meager 60hp by about double! It's also a nice 8 plate job weighing a lot less than my standard A10 clutch unit. Plus it has a cush drive, so the plan was to make it fit!
I am not going through the process here as it is not an easy conversion and not a recommendation unless you really need a super clutch.
Just here to show what I'm doing and why.
The two compared for size
8 nice fat plates!
Clutch basket offered up for fitting
Gear wheel cut for cush drive springs and pegs, and the centre fitted with the bearing carrier.
Assembled and splined drive/carrier shaft almost ready
