Hi, been a while, still trying to sort out the floors.
So I've been doing more tuning and still misfiring (on new plugs) so a mixture thing. Spoke to a triumph racer last weekend and I'll try no springs in the su2's and no dashpot oil. The mesh is to actually restrict the airflow as with the spit mk 2 induction I'm getting too much air for the little 948.
Then I'll work back up the three steps of increasingly richer needles as I go.
