Anyway, motor is coming together. Took a few photos of various bits, in this case the cams and rockers. The smaller cam is a Taida T6 so a bit of a hotup part which worked well with the 203cc kit. Compare that to the new cam, lift and duration. Matching rockers in the other photo. The Taida rocker is a step up from the standard ones and as you can see the new roller rocker is a big jump up from that. Lift is going from 5.1mm or 5.2mm to 7.?mm or roughly a 40% increase in lift.
The crankshaft is a neat fit in the cases. Not a lot of room to go bigger.
