Well I got to France and got home safely !
Managed about 250 miles on a mix of roads - bike is in for first service next week
Did 146 miles before the fuel light came on - and that was not all gentle running ! One of the guys I was with had a 2015 Kawasaki Z100SX - not quite in the same league as the H2 or a modern superbike but still a fairly quick bit of kit - we tried a could of side by side roll ons from 70 mph and the H2 absolutely slaughtered him each time. We were chatting about it afterwards and I told him I was just winding it on in top - and he said he was dropping to 3rd or 4th and hitting the throttle and I was still just disappearing into the distance !
