ESE's works engine tuner

[AndreasL]

Some nonsense and insights...

Haven't followed MotoGP for long I felt I needed to get the basics of the rules.

Clear as mud and... No, I better stop there.

340km/h is impressive though and a great show it was.

Vinamold (red).
Try it if you haven't yet!
Finally did a intake manifold, intake port, transfers and ex-port.
Super easy to work with and great results first time.

Prepare for a shock though if your porting skills are (down) at my levels.
Good thing is that I now know more or less exactly where to do some fine tuning.

Wonder if replicate all misshapes in EngMod would be a good idea?
Any one that have tried that with beneficial insight and result?

The Ryger uses a 90 mm C/C rod.You can use a long rod in the Ryger setup, but it is not necessary and it will lead to a rather high engine. And you will need a special piston anyway.

.

Why then if the bottom end is so standard are we not shown inside the crank cases in the picture of the production engines lined up, you know the picture with all the paper towels covering the crankshafts? I wonder if there are several different levels of Rygerisation? And soon we might get to see level one, the level that does indeed use the standard crank.

It's not for me to decide, Neil. But Harry Ryger takes a look here from time to time so maybe he'll react.
BTW: covering open crankcases just serves to keep dust out of the bearings. I bet you've done it yourself more than once.

Except the whole 2 stroke tuner world isn't that interested in seeing the inside of Flettener's engine. (sorry Neil just telling it like I sees it...)

The TF/TS100 is a farm bike engine, the Aprilia RS125 cylinder I had in mind is from a road bike and the RD400 115mm C/C rod is mostly about having enough height to fit a spacer/adaptor plate for the modified TF/TS engines water cooled cylinder.

I was expecting to change the rod when Rygerising the engine. And also replace the TF/TS spacer/adapter plate with the Ryger version. It has been obvious for a while that the Ryger piston will be a bespoke item.

Anyway that is all for later, the first step is to get a TF/TS 100cc air cooled engine into watercooled mode. The basics of the conversion is simple but there is a lot of work in the detail.

The big picture steps, successfully water cool a TF/TS100, fit a suitable cylinder as per NZ F4 class rules. Then get it and the ancillaries like frame mounting, digital ignition, 12V generator, water pump all running reliably and sometime next year or the year after when the Ryger details are known, Rygerise it.

No point in sitting around in endless talk waiting until all is revealed when the basics of the project are known and can be started now, laying a solid foundation that is race tested ready for a quick upgrade when the time comes.

TZ350, what kind of water pump do have in mind? electrical or mechanical? what kind of capacity pump would you think is the minimum requirement. sure the aprilia was massive ltr/min.. im at this point myself and i feel i can only go with the electrical in-line type with the set up i have, but the 12v pumps seem pretty weak on pumping capacity.. what do you reckon?

Bosch aux coolant pump found in many Mercs and VWs pumps 25l/min unrestricted @12v, about 1-1.5amp - not bad at all. Don't know how much juice it can handle, but 15v should work, maybe more.

Hmm, yes. Bespoke piston. Someone must make it. Maybe a few emails are in order.

Hello sales at Woosner.com, I'd like to order a spare piston for. .
Hello sales at Vertex.com, I'd. . .

You can see where I'm going with this.

frits im sure this is a question you can answer. is rygerising a engine something the less smart people like myself will be able to do ?

Fair enough, next time I show pictures of any of my engines insides, you shut your eyes, OK.

Also would Ryger be making some of the parts for us, like a piston and maybe the spacer and whatever it contains? Anybody can get basic machining done to their engine using mills, lathes, porting tools and a welder, but it would be easier (for most of us) to have specialized parts made up, by Ryger. It is their baby I have no problem with paying them for assistance converting an engine to their configuration.

We can indeed Dave....But I reckon you'd get a standard "we're waiting like the rest of the world" response....
My personal pick would be Mahle, you may get a "no comment" there.

Just a random thought while we're all thinking about our future Rygerised buckets:
How many road bike clutches (presumably embedded in all genuine buckets) will handle the 50 or 60 or 70 HP we're all hoping for?
How many of us are already struggling with clutch slip at our relatively modest outputs?

The power is made by extra rpm not extra torque. A Rygerised top level kart engine might make 70 HP but I bet a Rygerised modest engine comes nowhere near that HP.

I don't know you well enough and I don't want to insult you Peewee.... At the very least you'll need to be able to operate a CNC mill.

With the amount of kart engines on order there won't be enough spare production capacity to be able to take orders from privateers.
But there has been talk about producing kits for existing engines. Don't ask me which ones; I'm not sure I'm allowed to answer that, so I won't.
