Done some testing today at York raceway.
Seem to be heading in the right direction, have gained 4mph on my trap speed 104mph now, times were poor as expected with road tyres. My run was b170 on the lh side.

Highlighted a couple of problems though.
Carb needs more fine tuning as it was too rich causing it to bog down/hesitiate on launch & some gearchanges. I think its needle jet not sealing, the afr's are very rich on part throttle though so it could be a combination of both.
I probably could get away with it as is using slicks/full throttle launch, but with feathering the throttle on road tyres it didnt work.
I have damaged the gearbox, possibly the syncro on 2nd. It was ok for the first few passes then it wouldnt go into 2nd. It will ram into gear at low rpms on the road but game over for the strip so will have to change the box.
