Not a bad guess at all
As recommended had another play, its such a small adjustment, i started off a bit gun ho, but have got 3 decent positions, that all fall within one increment line on the cam, about 10, 15 and 20 thou advance give or take, smaller increments proved pretty difficult with my sausage hands.
I had previously fitted the metering head from the cabby to tim on it really seem to smooth out my spluttery bottom end, just needs setting up pressure wise i was toying with getting an innovate wide band meter, but might just save my money and put towards another rolling road sess
Thank you for your help boys, looking forward to putting her back togther over the weekend and having a blast
