ive only had my Mbike for 7 months and it alwys got around 230kms without spluttering etc. i hadnt even felt it splutter though, just noticed the levels and how much kms i got. you get a sixth sense about your bike fuel economy after a while. well today that went out the window....i did a run which, once we got out of the 60kph traffic for first 30kms, it was top gear, 110 kph, straights and sweepers and rolling hills for the next 80kms. maybe go down to 5th or 4th gear for steep hills, but with my mate running a daytona 600...and me on my 250....i was on full throttle most of the way. well 40 kms from home, we were on a 100kph stretch, with him behind me and the thing started to dramaticlly slow down, then it sped up again for another few kms....then another splutter and dramaticlly slowing down so i indicated to pull over and my mate must have been wondering what the hell am i stopping on a dangerous stretch with not a lot of edge off the main road...well my bike despite having a full tank at the start, had only 195kms on the odometer, and it had turned off before i even stopped the bike. i wasnt sure if it was fuel as its never gone below 230kms before so i thought i had an electrical problem. changed to reserve tank....and away we went again, till the next station. you remember the first time you run out?
