June 19, 201610 yr Author Thats what i have been thinking the bike won t rev at all but if i disconnect the tps cable to the throttle body the bike mis fires but will rev up after a lot of popping and banging i dont have the lead to plug in so i am just guessing to what the problem is
June 19, 201610 yr There is always an element of guesswork. Have you spoken to Birkett ?. He should be able to have a go diagnosing it on the phone. It'll be the injector though . £100 unfortunately
June 19, 201610 yr Author Yes spoke to Birkett last week and he said it is sounded like the tps connection and said to clean it i bought a new throttle body just incase cleaning it did not work and at least i would have a sprare,fitted the throttle body and it worked great so i thought it was fixed started it today and it started mis firing and sounded lean
June 20, 201610 yr There isn't a history of the fuel injector failing on the Ossa, but still is probable. We have had 2 cases with Ossa's where the ECU terminals at the connector were oxidised/coated/dirty, cleaning with Wurth contact cleaner type OL fixed the problem. The motor had similar symptoms to what you had mentioned earlier. Don't scrape the ECU pins with a screwdriver, as they are gold plated. Also had a difficult to solve problem with sporadic cutting out, traced to a break in one of the wires going into the ECU connector, not easy to find (I didn't sort this one). As a precaution, we use a dielectric grease on all of the harness connectors. Bye, Peter B.
June 21, 201610 yr Why not get the ecu read, this is why the ossa is such a great design, it stores the historic fault codes in a log, which can only be reset by user interaction(or clear log, then go ride..when fault comes in stop and read code/s)...it may not point you to exact cause...but you should be able to work it out..each transducer can be tested on its own BEFORE you go out and make a purchase(i.e. fault guessing,50/50 phone a ...), I think the ossa has been dissed because it were better design than a gg..so market forces/big bro pulled the plug.....real shame. Its interesting that the vertigo evolved shortly after its demise, i bet a lot of the R&D from the ossa has been inherited to the vertigo in a different wrapper now.I made my own usb data cable to connect to ecu. Made your own Cable:)?. Schematics please /Christian
June 21, 201610 yr Author I dont have a cable so thats why its guess work Birketts is closed for 2 weeks so I am just trying anything to get it going
June 23, 201610 yr Have you reached out to any ossa owners on here to see if any of them are close to you with a cable who could run a quick diagnostic? There must be someone rather than wait 2 weeks for birketts, that is ridiculous.
June 23, 201610 yr Author Clean all the connections and ecu put in a brand new injector ,new battery for the easy start ,new fuel pump ,new fuel filter ,new throttle body it must be wiring fault but just cant find it
June 23, 201610 yr Did you check the voltage regulator? Googled it and found the following info: The regulation functions of a Voltage Regulator unit cannot be easily tested. (We offer testing services on our test bench, where we can accurately diagnose a regulator failure. Please contact us to arrange testing services.) Regulation failures will generally present themselves by over-charging the battery. This may be noticeable by blowing up headlight or taillight bulbs from high voltage, or the battery getting extremely hot, and boiling the acid inside. This can be easily diagnosed with a Digital MultiMeter (DMM). 1: Connect your DMM to the battery terminals, Red DMM lead to the Positive (+) terminal, Black DMM lead to the Negative (-) terminal.2: Set the DMM to DC Voltage mode, 20V range.3: Start the engine.4: Note battery voltage at idle. It should be in the range of 12V - 13VDC at idle.5: Rev the engine to 4000-5000RPM, and check the DMM reading.6: The regulator should reach ~14.4 - 14.6VDC.If the voltage continues increasing with RPM over 15VDC, the regulation function is not operating correctly. The regulation function is not serviceable at all, the Voltage Regulator must be replaced. Regulation functions can be intermittent, and get progressively worse. It can be hard to test and be positive of regulator failure, but this is the easiest and most common way to diagnose this failure. Edited June 23, 201610 yr by tcrhino
June 23, 201610 yr Author Last shot before I find a large skip and put the bike in are there any diagnostic leads for sale only place I have found is trials and tribs but they have been sold out for ages
