beautiful ride and urgent service part deux

[nostatic]

Since the service light stayed away, I headed up to try and catch sunset at Saddle Peak, which is at the intersection of Stunt Rd, Schueren Rd, and Saddle Peak Rd google map).

Made it for sunset (see below) and then headed back through the canyons to Pacific Coast Highway and home. The ride was great - about 60 miles of twisties except for the 5 or so miles of PCH. Then coming back on PCH, not more than 200 feet from where my engine cut out yesterday (I kid you not), the warning light comes on, the bike dies then comes back (I was doing about 35mph), the LCD says "URGENT SERVICE" and this time the engine is pulsing between about 3K and 5K, back and forth, back and forth. I quickly hit the emergency blinkers and ease off to the right should (right where I stopped yesterday - at Sunset and PCH). I shut off the bike, then turn it back on. It starts up but the red warnign light is on and it says SERVICE (the urgent is gone, just like yesterday).

I decide to ride home just like yesterday, but after about 100 feet I pulled over the the right and stopped. Shut down the bike for a bit and opened the gas cap. There was just a bit of vacuum, and I had at least a half a tank of gas, but I was just curious. The bike was off for about 15 second (10 seconds being the usual rule for "clearing" electronic devices). Turn the key, hit the started and the bike fires right up, the red warning light is on for a second then goes out and the SERVICE is gone, with my trip mileage back. I finish the ride home.

So...I'll be calling the shop Tuesday (they're closed Monday), but it's got to be something wacky with the ECU. While I'm happy that I could ride home both times, it does not give me a warm fuzzy. I was planning some day trips but not with it behaving this way. Too bad because the ride otherwise was brilliant.

And so it goes...

Very pretty.

Funny that it happens in the same place.
There aren't major radio or microwave emissions any where near there are there?
Perhaps they would interfere with the ECU.

actually I was up near major comm hubs up in the hills. Down where it has happened is a major intersection (T actually, where Sunset Bl. hits the ocean at PCH). I was trying to remember if I killed someone and dumped the body there or something in the past. Some bad juju or whatnot.

I have no recollection...

That post made me laugh

Sorry I have nothing to add.

Great pics though.

Perhaps the NSA has a huge underground center overthere, indeed interfering with your Shivers ecu

Looks like a beautiful place to go for a ride.

Man, i wish i had roads like that near me.

I wonder if it's related to the fuel tank, perhaps not enoug/too much vaccuum. Something similar happened to my brutale in that the vacuum was causing the fuel line to collapse and bike wouldn't start, just a thought.

Something that you may have fixed when you opened the gas cap???

i had the same exact problems you had. went for my first ride today on the new bike and got the same "urgent service" message and the bike would start running real bad. Then i shut it off and back on again and got "service" then one more time got nothing. took it straight to the dealer and they scanned it and got some codes regarding the front and rear intake manifolds or something to that nature. They are going to call aprilia in the coming week to find out what is going on. also when the bike runs like poo when you get the urgent mode it is going into "limp mode"

[catch2otwooo]

nostic, did you ever get it to the dealer? if so what was the problem or codes you got?

I'm going in wednesday. Friday I got tied up with work and the weather was nasty here as well.

During your ride, did you cover significant elevation changes and/or temperature changes? One working theory is that when you start the bike the computer optimizes for the conditions with a pretty narrow allowed range. If you then ride into different atmospheric conditions, it can confuse the ECU. That's the theory at this point...in my case I went from about 2500' and 90F down to sea level and about 70F in the course of the ride down.

[catch2otwooo]

well i wouldnt really call it a significant change in elevation. We did start a little bit inland and ended up by the beach but i doubt it was a 2k + change in elevation. temperature was about 65-70.

i will note that both times were at slow speeds going through town. i believe if my memory serves me right, i was kind of feathering in first going through town or just going slow in first. please keep us posted. my dealer is trying to contact aprilia this week so i guess we should both know by the end of the week sometime.
