ESE's works engine tuner

I think husaberg has the right idea. O-rings fail a lot less than paper gaskets. But it would depend on wrether you have access to a CNC mill.

Yes, trying to see if we can run coolant through casting cavities that are normal empty air.

I do, with the AG. One surface is less than a millimeters wide. I use high temp sealastic. So far so good.

While I have your attention, where can I access the current Bucket Engine rules.

So what's that telling me, twostroke up to 104cc ?
Auckland buckets telling me up to 107cc, ?

why stop there appendix A says 110cc

my understanding was if you went over 104cc liquid cooled it was to be 24mm carb area restricted?
pretty sure most of the rules changes have came from ESE ideas....
if the crept up the cc for 2t to 106 or so H100/MB100 could use kt pistons without destroying.

[Flettner]

So, 104cc is it then. I don't want the intake restriction.

Good to know, very encouraging, thanks.

As I remember it, 110cc overbore allowance came in for the 100cc guys to be able to use 52mm KT100 pistons. So they could keep their old two strokes going as good original pistons were getting very hard to get. And the 24mm carb rule for two strokes over 104cc stayed in place. Someone has proposed to MNZ this year to do away with that rule. But the new rules don't seem to have come out yet, so I am not sure what is happening there if anything.

Team ESE were very imaginative with the 110cc thing and in the tradition of Bucket racing. To get away from air cooling Team ESE destroked their engines so they could use water cooled cylinders like from NSR125/250 or TZR250's ETC.

The poor old two strokes are getting left behind by the big modern four strokes. This year there were some proposals like changing to unlimited carburettor and 125cc water cooled. To try and level the playing field a bit. We would still be limited to using non competition cylinders etc. Just the same as always, so anything homemade is Ok.

We dynod a stock RS125 Aprilia roadbike at 30hp.
That would be silly to allow as a starting point.

Oh and happy new year. .
