My Pearl runs a 1 1/8 SU with a GG needle. I only get something like 35 mpg, which I attribute to mostly driving around at nearer 40 mph rather than 30 mph to avoid antagonising the rest of the rat-race traffic behind. Maybe 40 mpg would be possible if we could turn the motoring clock back and pootle along 1930's traffic free roads !
