Why would you be doing anything in those conditions? This doesn't sound like leisure activities.

Don't you look at my accountant.
He's the only one I've got.

Flett, as I have stated several times, there has to date only been two actual dyno confirmations to my knowledge that the 3mm floor lift on a 54.5 stroke
actually works.
Jan did it on the last RSA , he made one higher , but then retired and had that recut back to 3mm.
I did it on a TM homologation test engine and that worked as well - but it was kept as a" factory special " mod only.
There are two issues at play that make things difficult.
One is that Jan stated the mod only worked at all , when the Blowdown had been fully optimized ie the Aux around to bore center and made as high as possible
before loosing power band width.
The second issue is that its easy to say - make the dam higher then grind it down if its too high , but the ground bore port edges are only reliable enough for a short dyno test session
and then it has to be replated.
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 got plenty of blow down time / area / flow, like I said exhaust almost round to half way round the cylinder with onlt one bridge and a relatively straight port outlet from each port wndow (water cooled one will be straight) .
I guess its just a shit farm bike moter, apart frim Nikasil cost, I'll leave it at 3mm.
195 - 130 (might actually be closer to 129, shitty castings😁

Made a couple of these the other day, I guess a little less now, some actual numbers 😁

Anyone know if exist V90 2cylinder or 4cylinder 2-strokes with rotary intake valve?
I saw only ones with piston and reed valve intakes.
JBB250 use rotary valve but a bit exotic way with 2 karbs

There is an enormous amount of info on the JBB saga, the V2 250cc and his other endeavours, at Pitlabe.biz. http://www.pit-lane.biz/t5627p175-ol...e-une-histoire.Originally Posted by jbiplane

Go directly to page 8 for the first reactions concerning the V2
Jean-Bertrand Bruneau was a genius.

Altitude of 4000m with a -15C ground temp.Flettner could probably advise on the degree of leisure that would be in an Autogyro.

Just Autogyroing this weekend, as it happens. 😁Altitude of 4000m with a -15C ground temp.

Great machines !
Neil, I know that the Butterfly Monarch is no longer available, the company does not exist anymore. But is there a comparable alternative with an as good suspension ? Most gyro's realy have poor suspension...

The Dominator gyro. Centre line thrust, the best to fly and most stable. Rising rate suspension with shock absobers.
Ive been thankfull of the heavy landing ability several times, while learning to fly.
RFD no longer exits but I do and I still build them (well did)
Im looking at re booting production when I retire in a year and a half or so. Ive decided Ill stick to the single seaters as they are by far the most fun to fly. Especially with a lite powerfull twostroke. 👍

Also there are plans around still to build your own.

Yes, but here in Siberia we use more safe and practical machines like
My friend is owner of company which produce such toys and sell a lot each month
I have a bit strange question.
Anyone have an experience to connect 2 crankshaft by some type of couplings which allow small misaligment like 0.05mm?
may be Oldham will work for?
Low personal B.M.E.P.
These work well.

Oil in injectors.
How well do injectors deal with 2 stroke oil?
Er. . I've changed from my beloved carbed HiAce to a Nissan with FI. Diluted but does the old premix gas go through the injectors without clogging them do you think?
Neil/Rob, any issues with large ratio and FI?
Don't you look at my accountant.

My 2 stroke fuel injection ran 20:1 oil mix. No problems with the oil fouling the injectors or my O2 sensor. But not sure what it will do to any catalytic converters or O2 sensors long term.
