If you go fully synth make sure to get oil specified for motorcycle engines which also lubes the gearbox. Some generic (car) synth oils will cause clutch slip. BTW I'm still a Silkolene man, semi synth in the road bikes and fully synth in the drag bike. Castrol Power 1 is also (widely used by drag racers and road race teams) highly recommended and can often be got cheaper than equivalents from other major brands.
when in doubt go flat out
