Hello MK,
thanks for the answer.
Sounds at the first point of few a bit late. Original it opens at 6150 and full opened at 7960rpm.

My cylinders are stage 3 modified and the exhaust is also custom-made.
With the original carbs was the down in the torque starting at 7600rpm.
At the area, where the PV is to ¾ opened. Until this point it is a straight line. A slight down starting again at 9100rpm.

That was the reason why my first intention was to start opening slightly later 6500rpm and full open 1240rpm later like original.

Now the carbs also changed to the Mikuni TM35.
In the moment is the setup a bit rich. 200°C at 2000rpm and 620°C at 10500 rpm (4°C air temperature).

I saw you are also from Germany. :smt006

Regard from Stuttgart (nearby).

In that case check out the PV and pipe manual on my Homepage. They both contain a bit more info on ignition curves and PV settings.

(If you don't already have it, you'll also find samples of my RD500 tuning manual)

Zuffenhausen, :smt017
hm, approx. 25-30km.

Why?
Do you decide to buy a „toy“ with 4 wheels? :smt003

But I hope you know, they do not use 2stroke engines. :smt005

The Olymp is in Weissach anyway ;-)
(for the rest of the world: that's where the R&D and the test track are located)

Yes, they are placed in Weissach.
But the premium tuner is in Leonberg. :mrgreen:

But my heart beats for the other schwäbisch car manufacturer. :grin:

I have the four wheel that is as close to a 2stroke a 1971 911s. I owned the 911s since 1973. The one thing I have not been able to buy as well as a lot of the early 911 owners are the second picture. The first is my car. I know a lot of owners including my self that would like one of them. The test drive bra Porsche tool

Wau, cool car. :cool:
My cousin is also still having an old Porsche 911-Turbo out from the ´80s.
Spoilers from the race series, cage inside and interior completely stripped down.

That´s like 2stroke in a car. :smt003

But he is not using them since minimum 15 years, only standing in the garage.

your cousin has a 930 3.3. The transmission is not a 915 but a four speed. The 930 tranny is awesome with limited slip. Have you ever made it to the Porsche museum. If you do check out my favorite Porsche. The "Großmutter" a lot of history behind that car :grin:

I checked you list about the bikes,
Some are similar like mine.
But my bikes are al modified. I do not like stock bikes . :smt003

But one important model is missing, a triple from Kawasaki. :smt002

My bikes are far from stock. The 250's are with pipes but the 500 and 400 all have suspension and pipes upgrades. I rode a Kawi triple 750 back in the early seventies. That is a death trap :razz: :grin:

Oh, a Mach IV, :shock:
really rare bike in the moment.

I like the Mach III more. More elegant, lighter and still enough power.
But you are right a killer machine. Bad suspension and nearly no brake power.

I modified mine. Rear Öhlins, front WP, 320 brake disk and 6 piston racing calliper from Billet. :-P
The brake is good, but WP spring at front and the Öhlins shock are too hard.

And the JL exhaust is making a horror able noise. :cool:

what would happen if the triple motor was to go into a newer frame like a GSXR with newer suspension. Don't you have noise regulations in Germany? I heard back in the seventies. The Porsche racing department install a flat eight with Webbers on a 916 body. It wasn't very long before the authorities told Ferdinand Porsche to get it off the street :smt013 :smt018 :smt010

Depends on your custom fabrication skills. :smt003

This bike is street legal in the UK with a "daytime MOT".
