ESE's works engine tuner

[AndreasL]

Here is the full Ryger pdf, just issued on the cik site.
Oh - I cant upload a 2.35Mb .pdf, why not?

You killing me wobs.

[wobbly]

OK, here is the download link.

http://s000.tinyupload.com/index.php...38728174353340.

These are the papers that will be needed to race the engine, unlike the partially covered up version on Facebook.

Thanks wobbly, but that link seems to be exactly what was posted last week...
Or what am I missing?

Ya looks the same. Maybe they posted the "good stuff" then unposted it. That certainly wouldn't be a shock. I tell ya if it wasn't for Frits being involved I'd have to call BS on the whole Ryger thing, by the looks of it some Ryger competitors already have. I want to believe but...........the unveiling is a bit of a cluster IMO

[wobbly]

The stuff on Facebook had pages overlapping - and P2 wasnt even there.
But this just confirms the shit fight that is going to happen when the first good tech officer sees that for example the spigot that blocks off
the bottom transfers shown on one page isnt shown on another page - or the Aux ducts in the Ex port shown in one page is missing
in the engine photo,or that a C port is shown in one place but is not there in another.
So whats legal and what isnt.
The rule in KZ2 is that you can remove material from anything shown in the homologation papers ( except the pipe ) but adding anything is very verboten.

Wednesday, 13:49, I downloaded all pages from Facebook, pit-lane or if it was even from this site.
Cant remember.
Including page 2.

Was expecting 30-50 detailed pages with measures and tolerances.
Now I'm just confused. How can anyone tune a engine and/or use this document as reference for scrutineering?

Not being in to karts may make me miss the obvious.

Edit: Frits posted them starting here http://www.kiwibiker.co.nz/forums/sh...post1130939977

So the 1st race of the season is that one in Italy or we have to wait more to see this engine in action?

4.02 - 7.02
Adria International

ITA

WSK Champions Cup
OK, OK-Junior, KZ2

Are we to assume that the only criteria applied when inspecting a Ryger piston for legality is MAX. diameter, 2 rings, and an oiling hole?
The document appears to be void of any additional description, material listing, picture, or drawing.
To ASSUME things during tech inspection, usually makes an ASS out of U and ME ........... Kermit Buller

In KZ2 the basic rules are - the carb is no go - 30mm Dellorto.
The pipe is no go.
The head cc is no go.
The ignition is no go - the static timing is adjustable.
The number of Ex and Trans ports is no go.
The gearbox ratios are no go.
And lastly you cannot add material anywhere.
The piston max size and the pin diameter are stated, but any shape and weight is thus allowed - letting VHM sell radiused timing edge units with
a special insert to suit.

What is allowed is mods to the head shape ( by removing material ) and changes to the port timing to a max Ex stated in the rulebook,measured
using digital protractor and a set size blade stop.
Also reed petals are free, but not the reed block dimensions.
No Ti rods allowed - our techs use a magnet to check.
But you can for example shorten the flange face on the cylinder - this shortens the pipe, without touching the pipe.
The basic components must "look " as they are in the papers, but this then allows "heavy" cranks as used for years in secret by the factories.

So - tuning is open within the elements that are not specifically homologated.

I am unfamiliar with the tech on any of the CIK shifty engines. But is it correct in this class, the pistons, material, length, shape, etc are not subjected to post race tech?
BTY I cannot find the paperwork on the CIK site. Do you have to be registered to access it?
Thanks... Kermit Buller

Kermit, i looked at many Kart Engine Homologation PDF`s and i never saw a Picture or detailed Information about the Piston. So it is not intentionally hidden by Ryger to keep one of the most interesting Parts (only regarding the Ryger Engine) of the Engine secret. It seems that you just not have to show the Piston or list Details and Dimensions of it in the Homologation Papers.

So in Conclusion one can say for sure, that for the most of us the long waited for Homologation Papers are a mid-big Disappointment because it does not explain how the Ryger Engine works, especially how it makes more than 70 rwhp....if it does at all...

I think when Time has come Frits will explain extensively how it works.

i think maybe, that if all who looked in on this web site came up with some cash, we could have ordered up a ryger engine... stripped it .. documented it .. and sold it on.. probably for a little profit on top

Has anyone heard if any magazines are going to follow this path ?

I'm beginning to think that until they're in the hands of the new owners, the Ryger details will remain obscure.
I hope there's not a non disclosure requirement comes with each motor.....

hey guys im making a alloy fuel tank and I want it to be about 5 to 5.5 liters or so. I been trying to find some kind of online calculator that can easily do the math so I can get it in the 5 to 5.5 range the first time but I haven't much luck. do you guys know of any fancy online gadgets that will figure liquid volume of odd shapes ? heres whats its going to look like. the numbers are just generic so you get the idea that its not symmetric from front to back

Not an on line calculator just some basic thought. what you have there is one big box with sides and ends cut off at funny angles.

If you combine the left and right side off cut then you have another square sided box. So the simple solution is to work out the volume of the big box and subtract the volume of the off cut side box. The end boxes are different but are worked out in much the same way by making them boxes but the volume subtracted of each end box is only half.

Anyway think of it as one big box with a lot of small boxes cut off it. You could work out a simple formula or a spread sheet would do it.
