After refitting the tub, I made the cutouts in the body for the front suspension and the exhaust.

I have also got further with my reverse mechanism.
The starter and reduction gear are from a yamaha FJ1100/1200. This starter rotates CW as viewed from front so this works for my application with a reduction gear in between. I had the gear measured, so for those that may be interested here are the details of the reduction gear:
SMALL GEAR:
Number of Teeth = 12
Normal Module = 2.25
OD (mm) = 33.68
Root Dia (mm) = 23.37
Face Width (mm) = 5.0
LARGE GEAR:
Number of Teeth = 55
Normal Module = 1.25
Normal Pressure Angle = 20
OD (mm) = 70.10
Root Dia (mm) = 64.39
Face Width (mm) = 6.5
Both gears are 20 deg pressure angle.
I am making up a drawing for a gear to be made to fit on the prop adapter to mate to the small gear. This being a 2.25 MOD its not a stock item, but I was expecting to get something wire EDM'd anyway. Once I get the gear modelled I will post the CAD file also. So in the meantime I finished the rest of the mechanism and installed it onto the motor mounts:

I have ordered a 1/4 turn to lock choke cable to operate the mechanism, will post an update when i get this installed
I also made up a bracket for a microswitch and a cam to activate it based on the clutch position.

I also installed a similar switch that is activated when the gear is moved into reverse position. I'll have to take a photo and post at a later time.
Oh, also got clutch and throttle cables installed. Just some fine tuning and pedal stops required before I can refit the body and move on.
