500 Two-Stroke Tech

Ride last Sunday, the chain reduction is okay. She is still going to a very slight wheelie at the first gear. :razz: But engine stopped a few times. :smt009 No fuel out from the fuel talk. :smt017 Hope the engine is still fine. And she is consuming a lot of fuel, 14 litres for 100km. I´m shocked. :s...

Hello everybody,
I buy sometimes spare parts in Singapore for my RD.

Today one of them informed me, that they have a new law finalized to ban 2stokers from Singapore.


Did somebody get the same information?

Modified the pilot jet to 17,5. First ride on Sunday with original CDI , short ride, 60km. Was running well. Water temperature 65°C outside town. EGT up to 600°C at full speed. :grin: The only problem was the chain reduction (16/42), too short. She is running at the 6th gear without any problem unti...

Oh, you are right, I measured the connection of the source-coils and the stop-switch. Shit. I expected a normal star-connection of the 3 source-coils like at the normal alternator (no ground connection at the central point). But you are right, it will make no sense to make a grounded stop-switch par...

That´s how I connected the Zeeltronic PDCI-24V.

The only thing what is strange, was that I had to loop O/B and GR.
because the CU was set to "NO TPS".

The CU is gone.

Sent already a mail to Borut.

With the original CUs is everything fine.

I was also hoping, that only a fuse is gone, But all of them were okay. The Zeeltronic CU is gone. :smt010 The handheld tester shows only blue screen. I´m not able to show pictures, getting the message: “Sorry the board attachment quota has been reached.” What does it mean, quantity of pictures or s...

So after 1 week in USA I did a new jetting (main jets) at the right cylinders and went for a test ride. upper 340 and lower 330 instead of original 350. To compare the EGT LH and RH. That was the plan. :smt010 After 2 KM the engine stopped. Also no moving of the YPVS after ignition on. Shit. Not wan...

At your picture I could not see the fork and front wheel. But the 4 piston callipers match also to the older forks. The R6 is having 5.5 and 3.5 rims. The Alb is normally not my preferred area, I´m a black wood forest diver. :smt003 But sure we will meet some day for a ride. You will be surprised ab...

One more question,
Is your rpm-meter well?
Mine is tilting up from 8000 rpm. With PDCI-24V CU.

O.K.,
last year one guy offered one from Sindelfingen.
Nice to hear that one more RD 500 is in the “Schwobaländle”, great.
Are you sure that the rims are from a R6?
Looks more like a FZR600 rims, style and dimentions, too.

regards from Sindelfingen-Maichingen

Nice,
did you buy the bike in Sindelfingen last year?

I went for a short ride. Changed also the PV setting a few times. But no big difference. I think first I have to modify the main jets. According to the EGT she is running to rich. :-o Throttle fulled open at high rpm only 490°C at the lower cylinders and 480°C at the upper. If I close than the throt...

Hm, for the torque hole it´s my fault, forget to save the data. :smt012 It´s in the moment 6200rpm start opening and 100% opened at 8000rpm. Ignition is set to: 19° 2000rpm, 29° 3500rpm, 18° 9000rpm, 13° 11000rpm, 12° 12000rpm The setting of the carbs is still original, no time for try outs. TM35/1:...

So, back to the RD :smt002 After changing the cylinder heat gasket and assembly of the new control unit the first quick ride is done. No water overflow of the radiator anymore. :smt003 Temperature is good, around 60°C. Changed the ignition curve up from the middle and the PV opening also changed to ...
