Bike:2000 Ducati 748 Mono
I found out the hard way that these parts are a common fail on Ducs.
Was riding down on 664 yesterday in OH (Hocking Hills), some of the better roads out there and suddenly, my bike wouldn't hold idle.
It started to backfire under load and just refused to go past 6000RPM. You could tell it was laboring hard.
Stopped off for maybe 10mn and checked some wires and everything looked good. Started her up and she ran fine for another 10mn on the ride back home and started to do the same thing
We stopped at a gas station and had some snacks for a good half hour. Rode back home no problem hitting the redline and holding a healthy idle and no backfiring. My pump is good (new) as well as my fuel filter (new) and air filters, spark plugs and wires new within the past 1000 miles. So the problem was problem electrical. My grounds were good and i'm damn certain the ECU is fine.
One of the guys I rode with told me it was probably the voltage rectifier/regulator so I got an upgraded part from electrosport.com
Makes sense since I was riding pretty hard and at some points, the bike wasn t seeing much cooling due to being stuck behind stupid trucks and cars doing 35 in 35mph zones
. My wter temp was hovering between 180F and 210F
Moral: upgrade your rectifier with one of these heavier-duty and better cooling ones. Lemme know if you've had this problem
