gen 1 best fuel

[flesh]

Yep, you've rumbled me Mike!
Thanks for pointing out the differences in UK vs US ratings.
I've always gone for the higher octane rating at pumps in the UK.
A bike shop I used to work at used to recommend Shell V-Power, and advised that Yams from this period run better on it. I always thought I noticed the difference on my previous thous, but can't really tell with this one at the mo.

My Gen 2 runs much better on the Shell V Power. "Almost" eliminates the crappy standard fuelling (mines a '10 plate with the newer ECU aswell). Also gives better fuel economy for some reason
