| DataTool Alarm?
One of the lads I work with bought a new 03 Mille. With both he and I riding it separately, he experienced exactly the same thing.
The bike was back and forth to the Aprilia dealer several times, with the ECU, Sidestand Switch, Ignition Barrel and Tilt Switch all being replaced. Still the same symptoms.
Matey then checked rsvr.net and found a lot of people with a similar problem. Turned out to be a DataTool Evo alarm being mounted directly to the subframe, instead of using a cushioning system. This causes the unit to resonate at certain (higher) revs and gives the same effect as a misfire.
Apparently this is a common problem, and despite the alarm being installed by a registered DataTool installer, wasn't picked up.
Long shot Chillo, but is this a pattern with your symptoms? |
