I have a 2012 Evo I bought 13 months ago. Just hit 10,000 miles last month. A couple weeks ago I was cruising home on the highway with a couple other riders, steady 75mph, a couple cars in the way so we go to get over to go around them, I twisted the throttle slightly, nothing extreme, just trying to add a few mph, and it started bogging down on me. To the point where even though I had the throttle twisted, it dropped to like 60mph before it would kick back in to full power. It did this about 10x over 20 miles/ Each time lasting roughly 10 seconds. It never shut off. But it was what I would imagine running out of gas would be like. No, I have never run out of gas in car or on bike before and yes there was a half tank of gas.
No warning light, no error code, battery is good at 11.9v.
Last week, without researching possible issues, I went ahead and replaced the spark plugs and air filter and put it back together and it happened again under medium acceleration about 2 miles into the test ride.
Also, since I had the tank off, I went ahead and pulled out the fuel pump and checked the filter. It was clean. Fuel spilled slightly, as expected, from the hoses and fittings when I removed it so I doubt theres a clog.
Yesterday I tested the 3 relays by the battery box because I didn't know which was which, and they all clicked and tested good. One interesting thing I noticed however was the little whirring noise, that I assume is the fuel pump priming, when you turn the key to the ON position only occurred once every like 5 or 6 times I turned the key on. Now this might be because I was doing it every 30 seconds listening for the relays and checking stuff. But shouldn't it prime every time its turned on or is that just me?
Im not fuel system smart, but I am handy enough to fix my own issues in the past on Jap bikes. This is the first time I have dug in to the Ducati besides basic maintenance items.
I did research, which was pretty tough to come by, and I read on the forums that sometimes the fuel pump wiring can short out or go bad inside the connector, correct me if im wrong please, and you would not be able to really tell by looking at it. I also read that a company called California Cycleworks HAD a new fuel pump wiring harness to replace a potential shorted out one without having to replace the actual pump. But going on their site, they no longer have it I guess.
I guess my questions are these:
1) Which connector is the culprit that I read?
2) Is there any new wiring harness out there to buy?
3) If I replace the fuel pump assembly is that part of the wiring that could be bad?
4) Does it sound like the relays are bad with it not priming every time even though they tested good and no errors on dash?
5) What other things am I overlooking that these bikes sometimes have issues with?
On a side note, as much as Id like to, I cant be dropping $1,000 into the bike testing every little thing. The company I work for was just sold last week and I will be without a job in a few weeks since I didn't have much notice and haven't been hired by someone else yet. So cost effective tests/fixes preferred please.
I appreciate anyones sincere input and help.
