Yeah this project will definitely need gauges.

Lot's going on at the moment, but I'm playing with the idea of tackling this...

I think an upgraded radiator would be cheap insurance against seizing the motor, it'd also be smart to tear the whole bike down on the bench and really pay attention to all details.

New rod/main bearings
Hone the cylinder and appropriate size piston (for CR upgrade)
Make sure everything else is within spec upon reassembly (valves etc)
Beef of the OEM cooling system with replacement aftermarket radiator
AFR gauge to watch things and keep detonation from occurring
Maybe hotter spark plugs to account for CR increase

My main question at this point is... how do we keep control of ignition timing? I've 'built' a few motors in the past -- but they were all EFI as opposed to carb, so I'm not really sure how ignition timing would work. With EFI stuff it's all simple fuel/spark maps and AFR readings to hone in on perfect tuning, but with the carbs on this bike, I'm not really sure.

And my other concern is... will it do wheelies if I successfully achieve this? Muahahaha!
