yesterday I had my Vitpilen at the first 1000km service and 2 changes are now obvious:
1. The dealer told me, that they programmed an update into the ECU, but I will not recognised anything. That is wrong. KTM improved the fuelling at deceleration. The engine runs now leaner (lambda 1.1 instead of 1.0) at closed throttle and below 4500rpm.…[Read more]
luckily I have no problems with gas leak up to now (ODO 480km).
But to be prepared, can anybody please tell me, where exactly the gas leaks are ? Is it at the fuel pump unit or the sensor ? Is it a crack in the tank or only a failed sealing ?
Maybe I can do a rework myself before running into that issue. I did that on my Duke V long…[Read more]
george replied to the topic "Sidestand down" When it's not! MUST READ, dont get stranded in the forum Vitpilen 701 Technical Forum 4 months, 3 weeks ago
had also this problem at the very first meter !!
The magnet still sticked at the side stand bracket, so I cleaned the side stand, glued the magnet into the hole at added 2 small punch marks.
I suppose, this problem is solved now forever……
george replied to the topic Anyone have any issues with the tank vent failing like this? in the forum Vitpilen 701 Service Department 5 months, 1 week ago
the tank vent is attached to a small hose, maybe this is blocked anywhere ?
There a 2 hoses, one for vent and the other for overflow. I pretty sure, the vent hose is teh on at the back of tank. Remove the front seat and you should find the hose behind the round canister at right side going downwards ….
thanks, Qwandree, for that really funny and amusing conversation.
Are this real answers from coober ?
If so, it is again a big piece of bullshit from coober….
Nothing against their products, I heard a lot of positive comments and I suppose, they work.
But their technical explanations are always like above, confusing, senseless and false…[Read more]
Can confirm it also, it is absolutely normal with all KTM/Husqvarna 690 singles with ride by wire.
The noise comes from a small DC motor inside the throttle body. This is controlled by the ECU with a constant position control alghorithm with a control frequency of approx. 1kHz, which keeps the throttle exactly in position. What you hear is the…[Read more]
When do you think, you can provide the diagrams ?
If you like, you can also send a message or an email ( I will send you the address, if you want use email) ?
That will be a great help for me to have the diagrams.
Many thanks and best greetings,
I have a wiring diagram for the Duke 4 from 2012, but until the Vitpilen 701 2018 there were a lot of changes.
So does anybody have a wiring diagram of the actual Vitpilen 701 ?
it’s no rocket science, so I try to explain a bit, what I did:
I use an Innovate MTX-L unit with a Bosch LSU4.9 broadband O2 sensor. Unfortunately the original narrowband sensor of the 690 has a much smaller diameter, so I couldn’t change it, as I did at the 390. So I welded an additional bung adapter to the header and now have both sensors…[Read more]
I startet a weight loss program even before the first mile on my new Vitpilen 701.
My first goal is below 160Kg wet !
So I did follwing up to now:
tidy tail from R&G: old 1760g, new 800g, loss 960g
Lipo Batterie: old 3500g, new 550g, loss 2950g
Tools removed (need the space anyway for my electronic stuff):
sorry to interrupt, but I gained some experience with ECU, O2-Sensor and airbox modifications in the last years on a Duke 390, Duke 690 and now on my new Vitpilen 701.
So firstly I would like to explain, how engine management in these bikes works:
The engines run in 2 modes: open loop and closed loop. Open loop is like it was in the past…[Read more]
see my comments on
Only removing the cover only is safe. When spring is here (germany), my vitpilen is run in, my broadband O2 and datalogger is installed, I will provide you detailed data about the lambda values, because removing the cover will be my first development step……
I am using an MTX-L from Innovate with a Bosch LSU4.9 sensor. You cannot replace the original O2 sensor, as this is a standard narrow band sensor with a smaller diameter. So I welded another bung into the header for the LSU4.9. The MTX-L generates a programmable simulation signal for the ECU, which is really helpful. So you can run the engine also…[Read more]
I am new here, but I have gained a lot of experience with Duke 390 and 690 in the last years with fuelling changes. I run a wideband O2 sensor with datalogging to control my fuelling to prevent any damage running too lean (or loosing power when too rich).
From next season on I will transfer all my experience and electronic stuff to my new…[Read more]
