were going to travel down through france belgium, holland, germany, austria, slovenia, bosnia and herzgovenia then ferry from montenegro to italy, south of france inc monaco, up to switzerland and lake geneva, then to france, luxemborg and back to blighty

six of us going, 3 beemers with fancy suspension etc, a yam 1300, a gpz 1100, and the falco.
got to that point today when i realised that its coming around quickly with a bit of stuff still to do. tried to get oil today, and had to order it specially, so not changing the oil till next week. gonna give the bike a once over and put the 16t front sprocket back over the weekend, need to get MPG up a bit, so as not to be forcing to many early stops.
anyone know what tank milage to expect at constant motorway sensible (80-90) speeds, with 16t and std can and chip put back. been getting about 125miles to light coming on up to now (sl carbons and chip). also any idea what range is from light first coming on, to oh sh1t i`m out of fuel!
