does any one know what rpm the saigon taffy copy produces its best torque and power and for how long,
running one on a cast 230,with a sx200 gearbox,16 tooth,rear 46,according to the gearbox calculator it is pulling 4.51 final drive,and should be doing 67 mph at 6k.
on the road it will sit at 60mph all day but struggles upto 70,
whereas my port timings are probaly suited to 7500 to 8k rpm
just wondering if the gearing is a bit tall for the kit,probaly putting out 15bhp ish at the most.
