Well have been a lil quite for a while but have been busy, but not as much with this project as i would like!
Been trying to sort out my recently finished vespa, has taken a lil longer than ive hped a will need to go back for another dyno as we had an electrical problem last time, which stopped us final tuning the igntech ECU, any way just waiting on a new exhaust from Germany and it will be back to the dyno.
got a free Sunday so started some machine work on the engine for the test rig.
machined the side cover down to remover the kick start, going to make a rolling starter.
Here is the start of the billet head for the motor, as you an see it is a lot larger than the standard head to aid cooling, im also currently looking for info on Kawasaki H1 pistons, im currently considering using a wiesco version for this motor but need to find if the ring pegs are in the right place, so if any one has any info or can point me in the right direction that would be much appreciated.

What size bore?
Dont make an aircooled cylinder. It is not worth the anguish.

Good to see you back Nicholai.
I would vote for a water jacket too, keeping heat under control is a whole lot easier with water.
