0.8mm might be enough. Really sure that 0.6mm is too small though. The 118 main jet could be enough if your on 110 now.
At 1/2 throttle is where most time is spent so this has to be the economical point. When you move the pilot jet from fluffy to correct its all going to get a bit richer again. Need some ceiling to move in.
When correctly jetted should all finish with the clip in the middle with all throttle positions holding steady temperature.
Still need to set the timing and correct spark plug after this is all good. It won't mess the jetting up too much
