    Which is why I prefered your suggestion of a 10% overbore limit for all myself, because it covers everybody.

    but the same reasoning is not there though. That's the crux.

    I really don't care. My next new build will be stock stroke and KT100 probably at a start size if 52.6+

    I asked about 25hp 2T buckets and Jason's bike was mentioned. The other part of my question was "racing at the moment". When was the last time we saw Jason's bucket?

    There has been mention of self-serving amendments. However the other way of looking at it is that denying other racers a cheap alternative part could be seen as self-serving the person doing the denying, as in "I" don't get an advantage and therefore "I" will oppose this.

    Guys running aircooled 2Ts years ago grabbed a huge advantage with a capacity limit increase to 125cc, a 25% increase. There was no advantage to the H2O 100cc 2Ts but I can't remember hearing any bleating, and I would have. I made the proposal and went to conference to argue for it. I also proposed a 4T increase to 140cc, due to availability(I thought) of available oversize pistons. No other reason though it did seem to be asking a bit much of a 125cc 4T to keep up with Jimmy, not that many others were anyway. Subsequently the 4T size went to 150cc, again without much bleating about self-service and also without a compensatory increase in other engine configuration capacity limits. It made perfect sense of course in that FXR150s were allowed to compete which probably saved bucket racing from extinction(maybe).

    It isn't like there is a number of 100cc 2Ts that need just 2cc more to start winning. It's a cost thing plus the small incremental sizes that will extend cylinder life many times over.

    Buckets is about using what the rules allow. You can have your KT pistons right now simply by de-stroking, just as us 125 racers get to use decent length rods and wiseco pistons by extensively modifying our cranks (and then we only get about three oversizes, and only one in my case). The destroked 100's get countless oversize options due to tiny increments a big win which is well deserved for the effort put into the crank and motor. But wait for it, the real advantage is getting a high tech piston specifically made for air cooled race engines with a fantastic quality thin ring that can rev to 14500k all day long! Again a well deserved reward for the effort put in to motor, kudos to all that do.
    Note any 100cc bucket racer can already use KT pistons you just add a 24mm carb and you're good to go, and as already pointed out this still won't change even if your rule change does go through

    Simply by destroking, - wanna tell that to my two broken cranks? Aircooled piston into a water cooled barrel, piston designed in the 70s. Considerable over square engine. It's just pants all the way. Currently we get 4% oversize as it has always been.
    Don't you look at my accountant.

    To provide some parity between 100cc h20 and 125ac two strokes and it does it nicely.

    I haven't broken any of my repinned cranks, but otherwise you have pretty much described my engine .... its Buckets.

    So Rob, you've done well to reduce the impact of the 24. But given some development and a 35mm flatslide would you bet against getting more power?

    I think cheap is a great idea and nothing is stopping you now. You don't need a rule change to do that, just run a 24mm carb and air cooling and you're sweet, but if you want something different just be sure to include everybody in the benefits, or at least not start to disadvantage a section of the community because something suits yourself.

    With my proposal I advertised it for comment before submitting it then ensured that people were aware of it so they could make submissions to MNZ on the proposal if they wished. Thats democracy and doing ones best ensure a good outcome.

    Proposed rule changes submitted by stealth for the benefit of a few ..... I am not sure what that is but here is your chance to tell me.

    I think this is a futile debate the only way around this impass it is to ask for a rule amendment banning any ethanol based fuels
    Pretty sure the majority of the 4T brigade would back that.

    I have a document here from a world renowned physicist and 2 stroke expert that clearly saying ethanol based fuels gives air cooled 2t an unfair advantage over liquid cooled bikes of smaller displacement and over 4ts given a displacement leg up based on running leaded or unleaded hydrocarbon fuels. I'm picking the MNZ would have to consider his opinion somewhat worthy and impartial.

    I am not sure what to call it though any ideas?

    Only that they would be running a considerable displacement disadvantage unless they stroked them. Can't remember what they go to but 112-117cc (Mb100) or something with no wait for it no oversize's.

    Rob clearly a 107 air cooled with 24 km carb would be up to 23cc smaller than allowed. That would be dumb and you know it. You always drastically shoot down anyone else getting an amendment but try push something that suits you and often disproportionately. That is self interest personified.

    By just changing the carburettor to 35mm and tuning it properly, ..... yes.

    Not a flat slide, but a serious back to back comparison between a 24mm OKO red line and a 30mm OKO blue line. Everything was carefully optimised between tests.

    My thoughts from this experiment was that there were bigger blocks to my engines performance than carb size.

    Hence need to optimise for larger carb. But clearly an improvement in spread straight away. I'd be pretty happy to see that improvement for a mod I'd done. 35 is a conservative size for a 125.

    It would be cheap, I thought that was the bums on seats point.
