Do you think they are going to admit to bad fuel where you brought it from, unless they had many complaints then they have to, been caught out once from a bad tank of fuel on my 2013 Thurxton, filled up from a near empty tank just got down the road and it started to misfire and carry on, next day the bike wouldn't fire up at all, but because it played up straight after filling the tank (was running great before that) so I drained the tank and had a fuel can full for the lawn mower and put it in, the bike fired up straight away and ran great again, did complain to the servo about it and got the cold shoulder, but found out a week later a few people had the same problems with their cars running sick, never did go back to that servo again.
The fuel I drained out just didn't smell right or the colour just didn't look right, it was 98 premium fuel as that's all I run in my bikes.
