Guys beware with 98 Octane BP fuel... From another forum: BP fuel 98 in particular has changed. They changed the additives in the formula and it seems to create some problems for certain bikes and high performance cars like porsche. I had 7 bikes in total that came in with complains that the bike lost power and a lot of soot formed around the exhaust end. I have contacted BP yesterday and they are aware of the problem. Will let you know once I have more info.
