This afternoon, as planned, I removed the 50mm carbon fibre Termis and replaced them with 54mm titanium ones plus the 50-54mm link pipe. Now I have to fit the ECU (54mm open pipe) that came with them but that’s straightforward. I also now need to find some spacers so I can fit the right hand footrest back as it now won’t fit due to the increased pipe diameter .
There’s carbon fibre and then there’s carbon fibre. If one wants to see the difference between a genuine Ducati (or made for Ducati) piece and a 3rd party one of unknown manufacture just take a look at the photos below. The top photo shows the chain guard and brake line holder. Look how thick the DP one is (bottom in the photo) compared to the non-DP one. This photo shows how thin the rear hugger is on an unknown make 3rd party, just look at all the pinholes that only become visible when it’s held up to the light
This afternoon I set about changing the ECU as a consequence of which a couple of questions arise. 1. there’s an earth connection going into the case of the ECU, I presume there should be, it all looks original and disappears off into the loom. However, it’s affixed to a long M6 bolt that‘s one of 2 which secure the ECU to the battery holder. The hole they pass through on the ECU though is 8mm in diameter so the ECU will wiggle around on the M6 bolt which doesn’t seem to me to be a very secure earth connection if that’s what it’s meant to be. Right underneath it is a threaded M6 socket/hole (the one with the screwdriver in) which would make a much more secure earth connection. Is it right that there’s an earth where I found it? 2. second question. Is the tape around the cable to ECU plug standard? The same tape is used in a number of places on the loom so I’m guessing it’s OEM but a) it’s deteriorating - is that normal? and b) once removed the ECU plug is very very loose & wiggly, can’t be good for the connections of all those small wires. Should there be a rubber waterproof boot or something in that area?
Thanks Chris. Mind you Luigi did a bit of a shoddy job on it, I’ll have to do something better when replacing it.
Whilst all the tools were out and before I went back into the house to research the ECU earth question I thought I’d lift the tank and take a look at the front injector connector again. Took it off and sure enough one of the connectors has been pushed back into the plug. You can see the one in the right is more recessed than the one on the left. I’m convinced this is the cause of my intermittent misfire. Every time the connector is pushed onto the injector the spades in the injector push the connectors back down the plug rather than have something firm to push against and thus connect fully with the connectors. The poor connection with the injector is what’s causing the misfire IMO. It’s as though the little tabs that prevent the pushback and hold the connectors in place have either broken or are simply not doing their job. As I’m wiggling (wiggle is the word of the day today) the wires they both just came out of the plug . Having had a close look at them and the inside of the plug I think the culprits are the tabs which the screwdriver is under and if I bend them out then push the connectors back into the plug they may hold firm. If anyone has any insight please do share it. Alternatively I may need to replace the entire connector
Hi Paul. Apologies if this is a daft question, I gave a bad cold and head a bit fuzzy. If you think it’s now a simple connector at fault, why replace the ECU? Sorry if you have covered previously, I can’t be arsed to read back (honest!!).
