Three other dealers tried to fix this. What the F....k were they playing at?
In this episode, I'll be taking a look at a Ducati ST2 that's apparently unfixable!

I think you give other bike mechanics way more credit than they deserve. The reason I watch you is because you're cleverer than any bike mechanic I've been to. Well done for not just throwing parts at it. And yes bmw were famous for overtightening cable ties and creating tension where tension shouldnt exist.

@SuperbikeSurgeryTV you're welcome. I just wish you lived in Australia. They two bmw specialists I use for my collection of bikes have about 20% of your skill-set. Great blokes but they don't have that thirst for knowledge that you obviously do.

Cable ties are my pet peve! They hook upto the protective part. Which rides up the wires making them exposed. It can also act as a sack to collect water.

Awesome content Jim, I’m a car mechanic of 35 years and just completed the last 5 years at a Suzuki BMW franchise (bikes) here in NZ. I’m a Suzuki guy but watched the BMW tech working and I can tell you now there was very little support from the dealership’s management as far as technical training and support went… he was a talented mechanic and it was only that he was bright and tenacious that helped him solve some of the electronic faults and issues on the BMWs he worked on. Suzukis… a walk in the park compared to Beemers on the over complicated electrics/electronics they put in to their bikes (and cars) I’m now retired and spend hours watching you work and solve problems as you do… really enjoying it! Keep pumping out the content Jim… a lot of mechanics around the world are watching and gaining knowledge thru your work. 😊

Years ago I had an issue with my firestorm. It would cough and fart coming out of rbts and 2nd gear corners. I tried replacing all the parts I could think of over an 18 month period. Ignition pick up, ECU, TPS, carbs, coils, leads, plugs. Nothing worked until I changed the plug caps. I kid you not there was a crack on the front one under the rubber seal. Changed it and the feeling of having fixed it was just the best!!

@SB-vb8ch 3 ай бұрын

Don't know these systems specifically but it looked like the common connection is actually the signal ground which will supply all of the sensors, the raw 5v is generally for APS, MAP, & TPS. Most temperature sensors have the pull up to 5v inside the ecu so the variable resistance of the sensor forms the other half of the potential divider & therefore gives a voltage proportional to temperature.

Owner of 1998 st2 bought new and 2002 st4s bought used. Love the St2. St4s will cook your legs in the summer and run very hot. Had to add a manual switch to turn cooling fan on. Great videos. Not much love given to these less than popular models.

@nockianlifter661 5 ай бұрын

I had the ST4s which suffered from a myriad of faults that were intermittent. Somebody on the Ducati forum suggested I have a look at the big multi-pin plug on the left hand side under the fairing. It looked fine to me and I reported back. He asked me had I looked at the backside of the plug which I hadn’t. Gawd 😮 it was a green mess of decaying cables. I was quite surprised it ever ran. I removed the multi-plug and soldered all the cables instead. Bike ran fine after that.

Hi, good methodical fault finding process. However i cant help myself from commenting that the suspect sensor housing showed a lot of paint bubbling commensurate with a coolant leak from the hose above the sensor. This might have been the overall cause of the fault. Good dose of chain lube in that connector would be a good idea.

@tonymosley8676 5 ай бұрын

As a Ducati 907 owner this stuff is golden to me, same system with perhaps not even the barometric sensor, all inherited from the 851 I think, Ducati's first injection system... Mine has always farted occasionally at 3000 rpm, which unfortunately is where the engine stays 90% of the time, it recently decided to expand band of discontent that down to 2500rpm. In terms of things to fix that is far below replacing the cylinder head O rings...

Fantastic again. Echo others comments, basically not all mechanics/technicians/ engineers are born equal! I often fall into the same trap assuming that others know what they are doing when reality is that they are just wininging it, throwing parts at a problem and jave no idea how to logically diagnose a fault. You comtinually demonstrate mastery of your craft. Wish i had guys like you working with me!!

We enjoy listening to you waffle Jim, Diagnostics is defiantly lacking in the motorcycle world and with the complexity increasing something that needs more focused training on for the next generation techs. some good diagnostic gear out there nowadays but not much use without knowledge. your skill and knowledge on how things work enables you to nut things out and a pleasure to watch. i youtube a lot of the automotive diag stuff which helps me use on motorcycles, a couple of good ones are pine hollow auto diagnostics and south main auto repair LLC.

You may find that the map sensor is insind the dashboard, integrated into the circuitry..absurd i know but there it is...well at least it was for the 999 onwards. It looks like a vented mushroom cap made of rubber on the back where the plug is.

Think that's the baro sensor (AP) not The (MAP) 🤔

@thediddly 5 ай бұрын

@SuperbikeSurgeryTV ok, not 100% on the st2, the later models, i have: 749, 999, 1098, and 1098sf, they have air temp sensors in the nosecone, headlight support etc, and the pressure sensor in the cluster measures absolute pressure going by jpdiag software. There is no intake map sensor in that generation of ducs that im aware of in the inlet tract or airbox, which indeed is a shame as the value may very well be different inside the airbox. So i cant say for certain but good to know regardless. Thanks for your videos. I currently have a tps issue on my 999, and now fixed blocked injector(it stood for 5 years) and found via tuning software no tps value was recieved. Found it was an open wire with a continuity test to ecu. Why im saying this because with your videos of your process of diagnostics i was able to identify and now hopefully fix my issues. Cheers mate

As much as the simplicity of the fix seems easy, finding any intermittent fault needs to be happening to find it. As much as any have electric continuity, any connection itself can potentially be faulty. Finding is the issue.
