ESE's works engine tuner

[QUOTE=2T Institute;1130615412]Often thought about getting a MVX engine and bolting on 3 CR 85 cylinders, with an ignition and pipes would make a awesome roadie in a decent frame. The cycle parts were complete shit, as a L plater the choice was clear, shitter MVX, the KR 250 with those weird spinning discs, a cheap and cheerful RZ or the race replica RG. We all wanted the RG but could only afford the RZ, the KR was probably the best bike.

Got one of those ferreted away for a rainy day, I see KR's are banned as learner bikes now! That's a bit stink, she was a spirited bike to ride.

so how did you get a pic of david bain with the bike?

Berts TZR100 Sleeve was a slipping from memory.....


Some of Jans collaborations
Jamathi, Piovaticci, Bultaco, Minarelli, Garelli, Rumi, Schuurman, Aprilia, Derbi..

Oh i missed Cagiva too, not surprised he was there........ but don't often see it mentioned?

If the other cylinders aren't prone to seizure but the one with the heavy gudgeon is...that's the cause. I'd pick that the extra weight causes more side load on the piston which makes it hard for the oil film to say the least.

It would be interesting - and not hard - to build one up with 3 identical rods and rebalance the crank. Plenty of webs to take weight off to achieve the desired 100% of one side of the Vee balance factor.

it is in the Text i posted as an attachment exactly what you mention but the rebalancing the crank would be a great idea they changed the coolent routing as well but i have passed that direct to Drew.

Gilera made a tandem twin 125 mxer, I know of only 1 disc valve honda that was a 125 mxer raced in the All Japan mx championship only (it's not at the Collection Hall), Honda did make a RC125M twin mxer (with RIBI front end) but that was a reed valve. That bike is featured in VMX mag No26.




The RSA-before-there-was-a-RSA CZ125 circa late 80's

Must show you how to resize pics Lozza
The twin i referred to was def an tandem rather than a parallel it was abandoned when it was no faster where it counts on the track.
Lots of Stuff Honda did were not seen by the public although they were great and storing their stuff.
The engineer in charge of the MX twin project i refered to was Shinichi Miyakoshi, he likely did both of the ones you mentioned as well(Cause he was their MX go to guy)as well as later doing the RS500 (Design engineer in charge)
Maybe you could contact him he is likely on FB

Now that is a laugh. Even I could extract 40 HP from a blown 100 cc fourstroke. And a really dedicated foulstroketuner could make it 50. "But no competition engines" .

I shouldn't post this here for fear of being burnt at the stake.But geeze i never knew that Honda managed to squeeze so much at their first attempt.

Also added the Fuel injection stuff, as it looks like Dave could have been right. (about the DI ban) although i think it may have actually been a fuel pressure above 10 bar ban. (Plus he was wrong about most everything else)

Just some random shots of uniflow cores and castings, this one is a 650cc
The cores are exhaust port and water cooling ( on the exhaust side ).

So I should be looking at 75hp, minus a bit because my motor "only" has 4 valves /cylinder, say 60hp, minus a bit because it only revs to 18,500rpm, say 50hp. Nooooo sweat. With alcohol and nitro maybe, for about a second.

They were on Carbs too, so maybe no Intercooling either......my initial calc i did, before i knew what they got, was up to 45hp for a 100cc 4 valve twin intercooled with a half speed 300 cc rootes blower on Avgas with water injection. I couldn't find any forged dished pistons though in a suitable size. I hope you can.
I am guess the Honda's fuel owed a bit to F1, probably mostly toluene. Remember the life for a F1 qualifying engine was about 8 minutes.

Pattern making is a special art, and I would love to see more shots of how you go about making patterns, especially the ones for your new uni flow engine.

[TZ350]

I would love to see much more of Flettners patten making techniques.



Meanwhile I still have the software problem.

I came into work early so I could remove then re load the ProCal software but that didn't fix the problem.



But the Oscilloscope screen shows the TPS functioning OK. So thankfully it looks like only a glitch in the Gauge screen.

The Oscilloscope screen is great because you can select any number of variables and display and record them in real time as the motor is running.

So what you are saying is that I was right but it burns you so bad you need a throw away line claiming that I am wrong. I think you've been breathing the same fumes that Tackeo Fukui was inhaling when he stuttered (from that article posted) : "The turbo twin is easy to start, just like a 2 stroke but sounds much better"

C'mon! sheesh. No accounting for taste really is there?

no........no......no.... And no idea.
I prefer the sound of the Triple myself

Fukui-san went on to run the NR750 endurance racer project and eventualy became CEO of Honda( very odd by western standards to have a CEO that has the slightest idea of technical aspects of the products that company makes) he was in charge when the GFC hit and F1 program was culled but MotoGP stayed on, would like to think that was because he was a 'bike bloke'

Or the salesmen. Sorry one of those days.

Seems my Czech speaking pipe building friend has poked the ECU wasp nest with a stick.
A very large box of Ignitech units is in the air over the Pacific as we speak.
Hold onto your buckets,fuel injection is looming.

[F5 Dave]

Good to hear its working out. Good timing I think I've almost poked enough aside for another P4 for the 50.
