Have been running 87 grade fuel since new, stock EFI BA with TORs, with no real problems. Tried a 1/2 tank on 89 last weekend and noticed an increase in popping on closed throttle over the 87. Runs strong, but I was just wonderin....what does everyone use?

Always remember to be yourself. Unless you suck. Then pretend to be someone else.

Since going 904 my scoot seems to prefer the higher grade (98 here) over the 95 I ran before. A little more expensive, I know, but I've got really good mileage so I'm not complaining. Around 41 mpg or 5,7 l/100 km. To be honest, I was expecting the fuel consumption to rise after the BB.

you should run the lowest grade you can without the engine pinging. Octane is not a quality rating it is resistance to pre-ignition. With the 904 I can see a possible need for a little higher rating due to the increased compression.

I know that, but as I said good mileage - great performance - happy camper! Hasse and I will do a Dyno session soon, and we'll se what the numbers will be. I recently went back to the #42 pilots due to some hesitation on lower speeds, but that's gone now. A little more popping, but that's quite sexy IMHO...

Even with the 904BB I run mid-grade (89) and don't have any problem, pinging, etc. I can't see any advantage to go higher if not needed. I probably should be a little more picky as to brands as I don't favor any brand.

If you fellows don't mind spending extra $$$'s on a higher octane gasoline for an engine that really doesn't need it, why not just send your extra $$$ to Ian and I. We won't mind one bit and we really need it for more chrome.
