Hi Thanks for the reply.. This is my first fuel injected 1200 and I did purchase it with a bit of trepidation as I know bits are hard to come by for the CFI system, But ive bought it as a project so will have a go at it. Bit of background...
The bike runs fine above 3k revs but a bit lumpy below that, previous owner researched it and concluded it to be the PB sensor. He told me he swapped the sensors over and the running fault moved over to the other bank with the sensor hence he concluded it was at fault.
All vacuum pipes were replaced so I know they are good.
No idea if anyone has messed with the setting screws for the idle or the other screws they shouldn't touch, but your info is very interesting and a good place for me to start my investigations.
I did order some used sensors from a place in the states, so at least I had something to start with if there was a fault, and I also have some suzuki sensors which the previous owner bought after researching other forums, as apparently these will work on this system if all else fails. Parts for the SEI are pretty non existent here n the UK.
Bike runs fine apart from a bit lumpy at low revs and starts on the button, its the high idle that concerned me so if its something as simple as the idle linkage screw then thats great...I will keep you in the loop thanks!
