Thought I'd try V power.

[Simon.Pieman]

For what it's worth i filled up my tank with super unleaded before storing for the winter as i think being a higher quality fuel it will take longer to go off or when it does go off will take longer to get to the stage where it wont run.

At the end of the day it cost a few pence extra and its only tank of fuel on a bike so worth a try i reckon

It's not 'higher quality' it's a higher RON value that's all. Read VNA's post, he very nicely puts to rest the cobblers being said on this thread about fuels with zippy names.
If you are storing your bike over winter add fuel preservative to the tank to prevent it going off, then you can be certain it will be fine come springtime rather than taking a risk.
