View Full Version : Missing and/or Dying
05-31-2003, 12:26 PM
I've got an inconsistent problem but very dangerous one and I've had it before. 00 Mille. This is the second time that I've had an issue with these symptoms. The first time it was the main CPU that went bad. That was the last thing the tech tried since it was under warranty and that fixed it right up. Now I'm having very similar symptoms as before. The bike will cut out for a split second and/or lose total power going down the road. It seems to be more common right when I'm grabbing a handful of throttle. It doesn't happen all the time. Happened allot for a week and then about a week without occurrence. I ride every day. Seems to happen at about 7-9K rpms but has done it once at 4K when I was just cruising. Any time that it occurs where the bike dies, a quick off and on with the key to recycle it fixes the problem immediately. It happened just before I was about to go into a fast deep curve. Five seconds later if I would have lost power like that, I'm sure I would have high sided!! This time it's not under warranty and I just found out that the CPU costs a hare over $1000. I sure hope that it's something else or that the shop recognizes a pre-existing problem and works out a deal with Aprilia. I've got the Aprilia TI chip and pipe. Nothing new. About 8K miles since the first time. Any advice, experience or opinions are very welcome. Thanks.

Do you have a Datatool alarm fitted ? There was a fault with them that caused the motor to cut out at high revs.

Two other posters have posted similar symptoms.
Each spent alot of time diagnosing the problem.
One identified a broken fuel pump lead. The other
found a chaffed wire grounding.

:D Ill give it a shot. When this happens will it ever die, and not start for a while. If so , can you here your fuel pump prime up when you cycle the key, once it has died that is? Let me know.

Nope. It always starts right back up by just turning the key off and then on. I can bump start it if I'm still moving or hit the ignition if I'm stopped.

I missed what year the bike is, but on my 02 Mille R last weekend the kickstand switch puked at Putnam Park, shut down the motor and damm near killed me.
I took a little bit to diagnose it down that that part as the bike would start, sometimes run and be ridable and then just die.
Weather this is your problem or not, can't say but this issue has similar symptoms.
It's simple to cut the bitch off and get rid of it. There are 3 wires, 2 of them have to be spliced together, I believe the Black and the brown leads. The Green is unused.
I'll have pictures on my website this afternoon.

Newbie with used '02 Mille......same problem. Just came back from an aborted ride after it cut off doing 70 on the freeway(that was interesting) ...........second time this am....the other was coming up to a stop sign. It definitely is related to kickstand switch as every time I tried to place in gear with kickstand up it would stall. I pulled off freeway after several failed attempts to get going. I went to a side street and checked wires & switch ....no visible problems. The problem returned before I left the side street. I finally got it going again in gear & return home without another incident. It only happened once before a few weeks ago which I thought maybe I made a mistake leaving an intersection.
Madness - I looked on your site for more detailed description & pictures but could not find them.....pls share link.
Any additional switch bypass / elimination suggestions will be appreciated from others who have had the same joy. Anybody else had the problems and/or solved them?

Took it to Eurosport in Ft. Worth TX. They decided it must be the tipover switch went bad. First they just removed it. Doing that, the bike would run but I lost the right instrument screen showing only EFI. Then they tried to bypass it. Bike wouldn't start. So then they pulled one off of a new bike and got me going. Two weeks of riding almost every day and it hasn't happened. Dave showed me that my old one made a noise when tilting forward and backwards - not good, as well as sideways like it should. So anyone with these symptoms should remove the tipover switch located under the seat and see if it makes the same noise tilting forward and backwards as it does when tilting sideways.
