Ryger inquisition]

Harry's way of saying get the hell out of here Kiwi and stop sniffing around my workshop!

[jasonu]

made a few bits for that bike(not the pipe though), was one of the 5 or so 20 odd hp H 100's buckets

Am I missing something or is this bike really on display somewhere?

[MotleyCrue]

They didn't make any fantastic claims, they simply built a different engine and when it was up and running they slowly introduced it to us. They told us that it developed a certain HP at 17,500 revs (also with good torque) and said that they took it to 30,000 just to see how far it could go.

And none of that is fantastic ???

Let's not confuse "fantastic claims" or "miraculous claims" with being untruthful. Nobody is saying it is untruthful.

Big money will take what big money wants, and by "big money" I dont mean Harry lining his pockets with money, I mean those entities that want what Harry has got and intend to get it one way or another, if the Ryger engine is seen to have the far reaching potential we all hope it does.

its in a museum in Aussie there is a write up on the aussie bucket page, team mad dog or something similar.

Ken, (bit of a long shot, opening myself up to ridicule here! ) - we are of course assuming that the number of 'cycles' as opposed to the number of 'strokes' of the piston (ie.one stroke up, one stroke down =1 cycle) will equal the number of revolutions of the crankshaft?
I believe that it is possible to double the piston cycle rate without recourse to rollers, cams etc.

Willy,
The force diagrams were based on a conventional 2 stroke construction. However, if one say used a method such as suggested by a certain Brett S in post #19937, then things would be different. The more I look at the forces and their exponential increases with speed, and this with the short rod and generally well known limited bearing life at 17k levels, then there must be something else going on. Is it just the fact of lots of lube available, some cushioning, double acting combustion or whatever allows it to survive? Dunno.
Frits knows. Frits, how about another info clue or leak? It's been a while.

Hi,

just like many others I got hooked to this excellent thread, wife thinks I'm having an affair with some old love. My first bike was RD350 so she is partly right.

Unfortunately I have no information just some more questions to show my total lack of knowledge in these piston force calculations.
Does the late ignition made possible by HCCI effect the piston forces? I was thinking that it is the acceleration that is killing the engine in 30 000rpm, if that could be reduced somehow then it could survive. The other possibility is to have stronger/lighter "piston/conrod".

It would be also interesting to calculate backwards that if we had 30 000rpm, what would the other parameters be if the engine was to survive according to our current knowledge.

Yes it's a very promising project but there's no fantasy involved, probably all hard graft and a large dose of reality! ........and yes, I understand what you are saying of course and undoubtedly you are correct about "big money" but that's how it always has been.
I live in a small country where a lot of brainpower has been lured and dragged elswhere by "big money" - those big money countries then claim them as their own if they are successful and we are still just little old New Zealand with nothing but sheep and cows (and an obscure flightless bird) for the rest of the world to identify us by!

Holland is a little country too, but being part of Europe, they have access to a huge market for their engineering expertise which they are quite capable of exploiting and doing it directly from home and - they are very capable engineers and businessmen.

Basically I think we are in agreement - more or less.

Yea was confused by that pic. The barrel is MB100 but I thought you only got H100s over there. Perhaps there are H100s that use MB parts in some countries but would need new frames.

Mike has had 30hp from his, mine approaches that. Still more to come but OK for 1978 tech.

Yes some countries called what we had as the MB100 was called the H100.
There were three variants in the Hayes manual.
from memory the H100s we got after the Mb100 was left over run for an Asian country BlueWing got hold of and put on the market here hence the lower spec with 4 speed and points ignition.
The Gl145 was the similar sort of deal. (a market run intended for somewhere else)

I looked at that myself A typo as they are different the part numbers and sizes are above.out of my note book along with some old prices interesting to see how much they will have gone up.

To clarify the H100?Mb100 thing.
My take is the MB100 and H100a big fining and CDI are essentially the same bike. The Hayes manual doesn't even mention the MB100.
The S is what NZ knows as the H100 points and straight fining. But yet produced later than the MB100.
That's my take on it.
The H100SII which I have only seen in the Hayes manual had the H100 motor in a frame with down tubes bolted on. It is ugly will post some pics. Whoops it also has CDI I didn't know that.

The MB100 has the 5 speed the electronic ignition racier port timing and different fining its a better starting point due to its bigger fining. IMO
Those Aussie buckets had to run std frames

Won't work I will fix it later

[karter444]

does anyone know of any piston manufactures that do single ring pistons with the ring locator pin centrally located at the rear of the bore
to suit 250 mx engines
have tried vertex but even their single ring race pistons have offset pin locator to line up with a transfer bridge
cheers

the Site that I will link list the ring locations
http://www.pvlsverige.se/vrm/index/index22.html

I will add to the list later most are rods
but have a look at TKRJ and Prox plus makita can't find the site at the moment or they changed it site for sizes try some of the 250 karts like Rotax
can't remember who used to make the pistons for them? some Austrian company

[Frits Overmars]

question to Frits is : are we talking crankshaft revolutions or piston cycles (or both) when we say 30,000?

Both: crankshaft 30.000 x 360°; piston 30.000 x up, 30.000 x down. Clear enough?

Ahh iI had a H100S. The A seems to have the same barrel as the MB. Honda seems to have given 6 or 5 or 4 speed gearboxes out at random over MB50, H and MB100 depending on market. Keep reading different results in o/s mags.

Correct the Poms got the 4 speed I the MB50 restricted most other markets only got the 5. We and I think Aussie and the USA (one year only imported)got the 6 speed.
The four speed is an all up Ag100 style.
The 5 is the exact same ratios as the CB50 and XL100S.
All the Mb100's were 5 and the H100's we got were the 4.

there was also a MB8 which is a MB100 engine debored to 80 with a 5 speed only a few euro countries got those though I think.

The Cr80 aircooled is a lot closer ratios and bolts in although 5-6 is a bigger jump.
pretty sure the Takakawa and similar boxes use late model CR85 gears although there is other custom ultra close gear ones as well. All illegal for Buckets mind you and ubber expensive.

[F5 Dave]

Ahh now that's where you are wrong, the US got 5 speed 50s or at least some were, our MBs were 4, or at least the ones I've taken apart were.
The H100S was 4 but all down. The MT50 was 5.

Anyway I'm done being a trainspotter, none of this seems so funny anymore.
