Default RE: 98 octane fuel

ORIGINAL: Rebel78

I'm using 98 grade octane for my 07 Bob, would that help in decreasing engine heat or make it worse?? I got V&H slip ons & everything else is stock.
Same spec as my 07 FXDC, and I've started using 97/98 here in the UK, and it does seem to help, using the rule of thumb 'butt dyno' and follows what others have said above.

Won't go back to using 95.

Default RE: 98 octane fuel

I ran 100 Octane in my 07 streetbob before.

It was GREAT, No decel popping, better throttle response, no surging....

I ran it until my buddy told me the 100 octane at the 76 station is LEADED
and would burn out my O2 sensors...
