    Are those results just with the new exhaust or do oyu have other goodies we should know about?

    Carbon akra yielded similar results. Was four years ago but off the top of my head I think it was 120 bhp ish about 9 ish of an increase from stock? Anyways I agree. Was expensive but well worth it. Would almost certainly have sold on by now without the upgrade. Enjoy.

    I do have a K&N air filter fitted and i always run premium fuel(98 octane)..Also the guy who did the tune is well experienced and knows what he's doing..(a few trophies under his belt)I believe experience is what can make a big difference..
    Also my Yoshi R-77 is the newer version with a slightly longer pipe before the can..Maybe that made a difference too..

    Hi there; Octane rating of fuel. Do you know what the rating means ?? Unless you raise the compression above standard on the CB 1,000 R there's no benefit above 95 octane.

    The higher rating resists self combustion ( Knock ) but adds no extra energy to the burn.

    I know that 98 is higher than 95..
    But seriously,maybe i can save some money on fuel if the higher octane dosen't do much for performance..Thanks for the info Colvert..

    Owners Handbook: Use unleaded petrol with a research octane number of 91 or higher.

    If “spark knock,” or “pinking” occurs at a steady engine speed under normal load, change brands of petrol. If spark knock or pinking persists, consult your Honda dealer.


    As noted up there, UK pumps provide 95 ron as standard but 98 ron won't do it any harm at all - as COLVERT suggests it's when you start tuning the motors and the compression, that the higher octane (ie slower burn rate fuel) becomes necessary

    BUT IMHO there's no reason NOT to use it - just watch out for knocking / pinging with either, although I do believe that the CB has elements of automatic ignition / retard built into its system to help deal with this ...

    Well i think i might ask my dyno tuner what he thinks about the fuel rating and whether i should keep using the 98 or not..It was tuned with the 98 octane fuel being run through it at the time...
