ESE's works engine tuner

[Haufen]

Seems like there is no inner radius on the transfers of Luc's cylinder.

[breezy]

can you imagine how precise the transfer port flow/direction/speed would need to be to produce optimum cylinder filing and also the exhaust characteristics to achieve such an engine. bad enough with what we have now, maybe have to rewrite most of the 2t tuning as we know it today!

But think of the revs.

So what we need is for Frits to quickly sell the completed design to KTM who then for some unfathomable reason decides to put it into production as a 100cc road bike with their supposed 'ready to race' philosophy.And sell thousands of them, particularly in the Southern hemisphere.

Then I need to wait a few years so I can afford one. All this needs to happen before I'm too old to race competitively. . . . Which was probably a few years ago anyway. I'm a slow learner, I think I got to my peak when I was 40. It doesn't seem like that long ago.

hey guys since just recently i started working with the small cylinders i figure its good to upgrade to smaller tools also. today i recieved a smaller 90 handpiece and it looks perfect for the job . my full collection is getting bigger

[senso]

Interesting angle head, is that an eBay cheapie or is it for the cc specialty tool guys?

[peewee]

i dont bother with cheap crap from china . i got it from ccspecialty because they had the best price i could find but you can get it from other places aswell. i dont believe cc makes any of the tools but rather just distributes them. its nakanishi head. not exactly sure who makes the shaft handle

Jealous, was looking at them just yesterday, but will have to wait. I get quite some chatter with my 3mm dentist setup with larger bits adapted & its isn't quick or precise as it could be. But the money isn't there atm.

[peewee]

why not use a credit card then pay it back in 2 or 3 payments ? if i paid cash upfront for everything, i would have almost nothing

What bore size would you need 51mm bore , 51mm stroke? Whats max oversize for 100cc water cooled?

Just thank you for that thread! most interesting thread i ever read! Just one question: can anybody tell me where this chocky fish is available? i googled and can not find it. we only have chocky bananas available here in germany.

Husaberg has a cupboard full of them. He is always lurking around this forum so tracking him down will be easy.

husaberg, it should be noted is spelt with a small h as I don't like to show off...
I haven forgotten I owe you a few still for running the Northern Hemisphere Sprocket forwarding operation.........
So are Chock fish still just a NZ thing?

Anyway anyone got some decent pic of the Konig flat 6 I guess it wasn't one disk valve like the Four? King Konig I think it was called
Seattle Smithy?

If you were building one for Richban you'd start at 54x54

[F5 Dave]

Erm 104cc if I was to stay legal. Oh right

Then perhaps 50mm bore and 51mm stroke.
I've got this sleeve cylinder crank case underway again, should have the top and bottom patterns ready this weekend. and although it's to suit a YZ250 gearbox I was thinking about making an FOS cylinder ( after the sleeve idea turns to shit? ) to fit on this same case. 51mm stroke will fit no problem, case reed ( V force ) and transfers everywhere around the crank case.
How does the FOS cylinder run under the power band ( off the pipes )? Could we do some tricks to help this part of the rev range?
128 transfers, 195 exhaust? Somewhere to start?

I am no physicist but I think the FOS will need to run constantly in its power band so require a cvt?

Wouldn't we rather have a 500cc V4 Neil?..........
