I’m starting to think a very small crack in the block or manifold.

Dean,
Similar frustrating problem with Vee’s have been reported many times at the VSRI forum.

Since you have eliminated the top 2 causes, ECU and Fuel delivery, that leaves the
third, a Throttle Position Sensor going from bad to worse.

Evidently, a TPS can test good electronically but still be bad in operation. Only a
test by replacement is definitive according to the posts about successful fixes.

Best of luck, ride safe.

Secondary TB butterflies were removed. Techs wanted the diagnostic to be near stock a s possible so they reinstalled after test ride. Still cuts out at 3K.

Jeff,
There was a new customer DL1000 in the shop. The techs exchanged most of the sensors in the air cleaner, throttle body and crank position sensor, air filter temp and test ridden. Same with the EECU. No change. Still lost power at 3K. All wires to the sensor were checked and continuity tested.

Does your ‘strom have any sort of crank position sensor? I’ve found a few wiring diagrams on the web but some of the acronyms are ambiguous. It looks like there is a separate sensor for the secondary throttle that could be confusing the ECU. There is also a PAIR sensor. I have no idea what that is.

I suspect you are looking for a faulty sensor that has gotten worse over time. It is losing its ability to respond and the diagnostics may be fooling you. Often those cannot replicate conditions under load.

Of course it may not be the sensor itself. It might be a connection to the wiring harness or … horrors … a section of the wiring harness that has worn partially through and now has just the right capacitance to ground that anything above 3 kHz is AC coupled to ground.

Have you checked the full extent of the harness and all connections?

Matias,
My thoughts and prayers are for you friend!
Thank you for securing the V-Strom metal shipping crates!

Pedro Kauak, owner of MotoSur, Osorno, Chile had tech Christian working for 1.5 days with support from two other techs. After I explained what was done at your shop, Pedro and Christian worked on the fuel injection, then the spark plug wires then on the phone with Suzuki Chile to checked the air filter temp sensor and the cam shaft position alignment sensor. Pedro was involved in every step in analyzing the problem and trying to find a solution. They pulled/removed the throttle bodies and checked the vacuum ports, and metered all the sensors and all the hoses. They checked the rectifier, removed the secondary butterflies, nothing worked!!

After a day and one-half of intense service, Pedro charged me zero! He basically said after a day and one-half I’m leaving exactly as I arrived. No power after 3K RPM sooo no charge! You Chilean Suzuki dealers are golden!!! Thank you.

Matias – you rock! your english is so much better than our Spanish so don’t worry. we are sooooo happy that you have secured crates for the bikes. MUCHAS Gracias, my friend. We hope that your schedule allows us to treat you and your girlfriend to dinner but otherwise we will see you in California.
This problem with the bike is very confusing and we will all look forward to finding out the real cause.
see you soon, amigo!!! and am praying for your complete healing!
