I have owned this bike for a couple of weeks and everything has been fine with it untill now. I was riding along and opened the throttle while in top gear at about 45-50 to cruise upto the speed limit while doing this the bike hesitated and started to splutter. At 5500 rpm it stopped accelerating and I decided I'd been silly opening up an old bike at low revs so changed down a gear same problem so went down again and same problem. I then proceeded to play with the gears and throttle position to try and fight it through this stubborn patch ( was hopping it would do something different that I could diagnose). It would do anything different. When I pulled the clutch in it would stall then let it back out and it would bomb start but was very Jurkey. I decided there was a small possibility that I'd got low on fuel so I filled up. It only took 9 litres to fill to the top but afterwards ran completely fine. The problem is that 9 litres isn't a full tank so the bike wasn't low on fuel. Has anyone had this problem them self's.
