Ok, so replaced the oil pressure warning light bulb, and still does not illuminate when key is turned on. Disassembled the ignition module and connections look good at both ends. Regarding the occasional starter not engaging, I'll check the starter button next, but that issue may have been solved at the relay. Hard to tell right now as it only seems to happen when the engine is hot. So far engages the starter 100% of time when cold. But the oil light remains a mystery. Once I have the ignition back together I'll try a test light in the base of that socket (yup, should've done that first [emoji848]).

First question is, are you referring to the Tamburini 900SS of the 90s, or the 900SS of Terblanche that followed? I owned a '95 900SS/SP that I loved. It evokes a similar Italian lust as my V11 LeMans, but as everyone says above, they are very different bikes. The Ducati is all about the chassis, suspension, and fabulous lightweight handling. The only reason I sold mine is at 6'-1" I was never able to get my butt far enough back where it should be due to the position of the rear seat cowl. It's not a great bike for those over 5'-10". Otherwise I highly recommend them - so much fun to ride, but not for long distance like the V11.

Yup - the relays were the first thing I checked, I just put all Omrons in a couple weeks ago. I removed the relays and checked all the female spade connectors - all look great (bike only has 13k miles and always garaged). So just as a check, I switched out the #1 Starter relay with the #3, in the unlikely event the #1 Omron was faulty. I also rechecked my connections with the starter and kickstand shutoff.

You are correct, but have a look at the attached instructions for changing Dashboard Warning Lights: "Detach the resetting pin A". Go figure.

Thanks Docc, you are correct, the opening for the pin is slotted so no need to remove. Perhaps earlier models were not slotted holes and that's why the shop manual says to remove it?

...also, for removing the tripodometer pin, do you literally just pull it out? The service manual just says to remove it. Thanks.

Thank you po18guy and Docc! I ordered the T5 bulbs last night and will be taking things apart tonight. I am suspicious of the ignition switch wiring, as I've had a couple incidents where the starter wouldn't engage until I turned the key off and back on once or twice. I'm assuming once the two screws at the underside of the ignition housing are removed it pulls apart to expose the wiring.

Thank you Lucky Phil - will do.

Is the oil pressure warning light supposed to illuminate when key is switched to "on"? Having owned my 03 Le Mans for a couple months now, I've never seen it illuminate. The Owners Manual is not clear on this. All other dash lights work. Just wanted to check before ordering a replacement lamp and pulling things apart. Thanks.

Very interesting - thanks for sharing. I was all ready to purchase one for my recently acquired '03 LeMans, and went out to the garage to measure the wire length. Turns out mine doesn't have a lamda sensor. Very strange given that my '03 Le Mans dealer brochure proudly features it. Perhaps the early '03s didn't have them yet.

Very rough first prototype. 9" long x 5" tall x 3"to 4.5" wide. Significant storage when you figure x2. Attachment will be a challenge - only one bolt in that area to work with. Thinking plastic reinforced waterproof black nylon (similar construction as the Tekno bags).

Yes, SuperMoto Italia, a certified Ducati mechanic. Said it wasn't the first one he's done on a 900SS, and always the rear cylinder. He of course did a compression and leak down test first. I can't remember the numbers - was 20 years ago.

You're right, it is more like 6°

Ok - here you go. The gauges are different manufacturers, and the Guzzi stem is about 8" long and one for the Duc is only about 1". As you can see, there is about a 4°C difference between the two, the Guzzi gauge being the higher of the two. Makes me feel a little better.

Yeah, smoked all the way home. Ended up needing a new cylinder and piston/rings. Expensive lesson, so hope you can understand my sensitivity to this subject!😁

...but it seems all your examples are of water-cooled Ducatis. My '95 900SS/SP is air cooled, and when sitting still that rear cylinder gets zero cooling. It was not smoking before sitting in traffic that day. It's curious to me that the with '96 model year that added an oil temp gauge on the dash. Must have been a reason for that.

Thank you Pete. The fact you've had your Griso to 135° with no damage will allow me to sleep much better at night!

I agree, I'm not really worried about the oil performance. What I am concerned about is a repeat of what happened to my first air-cooled bike - a '95 Ducati 900SS/SP. Many years ago on an 85° day I was leaving Port Jefferson shortly after the ferry arrived and was stuck behind 50 cars and a series of 4 or 5 stop lights. 10 minutes later when we finally got through the last light and got moving, my buddy pulls along side of me and starts pointing at the back of my bike. We pull over and he tells me I have blue smoke coming out of one of my exhausts. Long story short, turns out that the rear aluminum cylinder (the rear always runs hotter on Ducatis due to less ventilation) warped due to overheating. The bore became slightly ovalized which allowed oil to bypass at the two new long ends of the oval. The '95 and earlier 900SS did not have an oil gauge and the overheating warning light never came on. I have no idea what the oil temp got to that day. So, I'm more concerned about the heat causing warpage than the oil breaking down.

...all of my water cooled bikes over the years typically run in the 180-190°F range (Ducatis, Triumph Daytona, Honda VFRs, etc). When stuck in traffic on a hot day I've seen the temps go as high as 220°F at which point the fans kick in. Same with friends' water cooled bikes, so I don't think this range can be considered too cold. Since the V11 doesn't have a temp read-out, I decided to get the oil temp dipstick. I will do as you recommend, and put them both in some hot water and see that they are calibrated equally. But again, my main reason for my original post is to ensure these higher temp readings on the Guzzi are normal and not doing any damage.

I've installed temperature gauge oil dipsticks from MG Cycle (German made) on both my '03 V11 Le Mans and my '07 Ducati Monster S4R 998 Testastretta (liquid cooled). The typical running oil temp range on the Ducati is 85 - 90°C (185 - 194°F), while the range for the Guzzi is 100 - 110°C (212 - 230°F), riding on an 80°F day on both open roads and in town with traffic lights. Is this much of a operating temp difference normal between liquid and air-cooled engines? Are air-cooled engines designed to safely run that much hotter than liquid cooled engines? The red zone on the gauge starts at 120°C, which I've never hit on the V11. But is constant running between 100 - 110°C normal and ok for our V11s? Any shared knowledge on this would be greatly appreciated.

I'm sorry, I have no idea what these would cost to ship to Norway.

I received my 10 Omrons from Online Components two weeks ago. See attached, they say Made In USA, and work fine. Perhaps they can sell cheaper due to volume (min 10 per order). Anyway, if anyone is interested in the other 5 I now have, will ship to the lower 48 for $20.
