Guys hello.

This is the second 2008 Ulysses I own. Sold the other one with 40.000 km on the clock and got this new-to-me one with merely 8.000km. Very happy with it.

The question is regarding TPS as you may realize by the title.

Summing up: its TPS keeps going out of adjustment!

How it happens: I perform a TPS reset by cycling throttle 3 times on and off. Go check ECMSpy or ECMDroid and see TPS oscilating between 3.8 and 4.0 degrees at idle. Go out for a ride, say, 20 miles. I start feeling the engine behaving badly, mainly in low RPM range. Get back to the garage and check the TPS at idle: between 4.5 and 4.7 degrees!

Repeated it several times, everytime it is the same. Exactly after reseting the TPS the behavior of the engine improves a lot, the bike runs completely smooth. But as it runs for a couple of miles it starts getting bad.

No CEL nor trouble code recorded in the ECM.

Question: is this something I should consider as usual on these bikes? Maybe I just have to reset the TPS everytime I go for a ride. I am putting it this way because my previous Uly behaved exactly the same.

Thanks all.
