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

Higher octane means more bang per amount of fuel used, hence better throttle response and fuel economy.
The carbed bikes, without fuel injection and ECUs can't adjust their fuelling on the go to take advantage of the better fuel. So while it may clean the engine out, and give a wee bit more power, the difference won't be nearly as noticeable. The engine may even run hotter.
