Hello folks!
I'm a new user from Brazil that is also a new owner of a 2008 XB12X Ulysses. Purchased the motorcycle 2 months ago with 17500km on the clock. So far I'm loving the bike, very comfortable for long rides.
Since the day I purchased the Uly I have already done some maintenance: new plugs, new air filter and cleaned fuel injectors. And yesterday I have changed its TPS and I'll now explain why.
The motorcycle always run very rough when I accelerate it just a little bit. To be more precise, it's rough when I open let's say 1% of the throttle. It's that time you wanna ride very calmly, maintaining say 20mph in 2nd gear. That's when engine behaves weird. It fails, it runs very rough. But if I open the throttle just a little bit more, engine pulls very strongly and the issue goes away.
Well, I tried to reset the TPS and it worked! Right after reseting I went for a ride and the bike was superb! Very smooth, just like it should be. But afterwards came back home and turned engine off. Went to bed and next morning went to work riding it and it was bad again. Same issue as before the TPS reset.
After that what did I conclude? TPS itself was the problem. So went for a new one, ordered from the stealership and put it in place. Same thing, first kilometers riding and bike was superb. Next morning same thing, the problem was back there.
I'm kind of lost, really don't know what else to do. Do you guys have any hint to help me?
Thanks.
Mario
