    Don't forget the CBR's. They go good to. Other people are working to develop there engine's as well. Its not just the 2 stroke peeps on this thread that are making advances with there engines. Bar gets moved every year.

    Feather weight part is right, not sure about the cleaning up though. I managaed two 1st a 2nd and a 3rd (and a couple of DNF's) on the FXR during the north island series, managed a 3rd first time out on TZ's bike and suffered no race DNF's. With a couple of chassis mods and a dialed back ignition curve the bike has the potential to win ever time it lines up.
    ps Why be dismayed by the mighty FXR, they're true race bikes with handling to be envied (FXR for sale drop me a PM )

    Where/when/how will TeeZee cash in on this huge win and who will be giving the blowys...???

    Nope TeeZee can't claim the prize. 31ps at 12,250 rpm with 18Nm (13.3ft/lbs) and 28.8ps at 11,750 rpm with 17.3Nm (12.8ft/lbs) and a good power spread.

    Hey I'm not trying to cash in on the offer, but I think a dose of Nitrous would do it.
    I've been told. Dreaming`s free.

    Funny you should say that, but we have dynoed a F5 here that was fitted with Nitrous

    Wish youse guys would post curve with 0rpm as datum to give a sense of perspective. Yes I know you never run down there, but makes curves relative to each other rather than an arbitary starting point.

    My first draft of that named him, but I changed it. Curve confused me when I saw it, just didn't believe it was possible.

    125 Aircooled with 24mm carb - bucket rules, is the challenge.
    I will gladly suck the chrome off anyones towball that can do anywhere near 30 Hp at 10500 - im bloody good at this shit and wouldnt even try - doomed to failure.
    That requires around 35 crank Hp, and equals 11.9Bar 0r 175psi BMEP at 10,500 - dreaming , as at that level you are screwing the tuning down real tight and the
    perceived advantage of any power-band width has just gone west.
    Mr Physics wins again and I keep my dignity.
    Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

    I would just like to have it on Record whist i don't doubt your talent Wob"I have never built and I have no intention to, Ever to build or ever attempt to build a 125 AC 2 stroke with a 30HP at 105000".

    Whist the suggestion at changing primary drive, i could make no sense of. It did make me wonder if one was to make their own engine one of the things that always scares me is primary drive.
    1 because custom gears are bloody expensive.

    2 cause they have to be perfect. So using another set of ready made gears is problematic for the amateur.

    I have seen in a quite a few right ups from seemingly reputable sources that chains primaries are more efficient.

    Now don't get me wrong, i come from a history of British shiter's with chain drives so i am definitely not a fan.
    But in the early classic movement the chains were replaced by Belt primary's for a reputed gain of 1.5hp to 2 HP per 50HP and no oil on wheels etc longer life etc quieter ...

    So if this is the case why aren't Real COMPETITION bikes running around with Belt drive primaries. As if it were true there would be an easy few HP there?

    Wobbly - To be honest your offer of a reward for a 3o HP @ 10500 engine is a powerful incentive for not trying !!

    As for how fast Richban's bucket is, and what size, you only have to watch the videos he posted and see Fish dealing to him and Andrew on his Longchin to realise it isn't all about horsepower.

    I've started on my new cylinder. Not totally sure where it will end but I'm aiming to break 30, and I still won't win.
    I don't think Speedpro or I are under any allusions as we have known for a long time that handling and riding and hp alone won't win races but it sure is fun to make and within the restrictions of the F4 rules, we havent been doing to badly at it.

    If you look back through my dyno graphs you can see a trend of increasing power spread with increasing rpm.

    My 30+ hp engine in fact has a wider spread of power than the engine Av used to clean up on at Tokoroa and Te Puke.

    ie: several x more than the bike was worth (depending if the tank was full or not)

    Not actually the point of the question though. But good to know as i was talking a High HP "race" engines and not GN125's. Was it to fit in the Dr350 crank?

    Whist the suggestion at changing primary drive, i could make no sense of. It did make me wonder if one was to make their own engine one of the things that always scares me is primary drive.
