I have got a ybr 125 and i am currantly running it in and i am wondering weather to use a high octain fuel such as Bp unltimate (97 ron), shell opimax (97 ron) or sansburys own brand super (97 ron). I sort of know the theory behind useing higher octain fuels, the higher the octain the more stable the fuel is so there is less chance of it miss fireing/ pre ignition of the fuel in the cylinder. I was looking on BPs website and they are makeing big claims about there new BP ultimate fuel they say that there is a 3% increase of power on average as well as better MPG and acceleration. I would like to know if any body on this forum has had any experiance with using high octain fuel in there motorbikes ?

I have just brought a brand new ybr and i was wondering how long you have to run it in for and what is the maximum RPM you can do wile running it in. I want to keep the bike a wile so i want to run it in properly. Any help would be apresheated. thanks pete
