Hi all, looking for some information regarding my mates bike, CBR1100XX '02, which has been an utter pain over the last year, with issue after issue really
Latest development, briefly, the bike was running lean and like a bag of hammers under load, so he done a fuel flow test (as in the manual) which showed just over 100ml in the 10 second test. Woeful, as it should be a minimum of 220ml. So, new pump & filter were fitted. Tested again, and approx 300ml in the 10 second test - a fantastic improvement.
However, when all fitted back together, ignition on & kill switch on run, the pump will not prime, no sound at all - and also, the high beam, tail-light, and number/licence plate lights respectively, do not work. Brake light, main beam, and indicators are working fine.
I've been searching on the forum and have found two mentions of the perils of this test, whereby, possibly when using a jumper it has inadvertently been put on incorrectly at some point, and therefore has apparently bust the ECM.
(The threads referencing this are here: https://www.cbrxx.com/engine-airbox-...arting-up.html & post #15 here: https://www.cbrxx.com/engine-airbox-...usb-pipes.html).
Do you Bird gurus believe this is what has happened here? Or could there be any other explanation? Assuming that the ECM has been damaged, is this also responsible for the lighting issues that have only just appeared since the pump/filter change, and fuel flow test was carried out?
The bike did fire up and run before the jumper/flow test was done, but since then only the symptoms written above are evident. Fuses and relays seem to be fine, but will test properly with a multimeter. Direct power to the pump and it happily works away.
Any pointers in what to check out would be very gratefully received.
