assume your talking superunleader (97 RON+)

On a stock map,  any difference will be neglible t ... get the fueling adjusted to suit and it may make a little bit more (little being the imperative here)

I use V power/BP Ultimate not so much for the extra power but for the cleaning agents to look after the engine 

this has come up before.... but they do rate the BHP figures in modern day using Premium fuel ...

I'm with GrNinja, use Vpower purely for the cleaning properties. Think it would be very difficult to notice a power increase.

with our track day coming up at silverstone i think i`ll give the race fuel they sell ago. think its 103 bhp,.
on my mates dyno we did a test with fuel boosters they do show a difference on the dyno but in real world riding on the road its hard to tell.

No wonder, those gas guzzlers were lucky to get 30mpg, he must have skinted himself lol

48mm carbs iirc correctly, didn't help that it had a tiny tank either

[2 pints of heavy]

i agree with G,....i don't notice any more horsepower but it does run smoother, i use it for all the cleaning agents.....and then sometimes i use an octane  booster
