unleaded

Just got my new MT 09 last Saturday and am wondering if anybody else is having fuelling issues between 2500 & 4000 rpm. Basically it feels like you are about to run out of petrol with a push/pull effect? On checking the owners manual it recommends premium unleaded or E10 and I'm wondering if it...

Just wondering what the concensus of opinion was.... Is it beneficial to use premium unleaded and pay the extra or do you not think there is any difference? I tend to put premium in but have used the normal stuff and can't say that I noticed any difference between the two. Cheers Tony
