CNF 1000 A-6 running problems

[Bikeman9281]

Hi Guys can any one help me I am a Born again Biker at 68 and I love my CBF 1000 A-6 having bought her from new she has done 50K miles and never missed a beat until now started with misfiring only small amount but today it got worse at low revs and cut out a few times and strangely the FI light was flickering she seems OK at high revs I put the 5 Petrol in her I assume that's OK or should I used the 10 any help or ideas would be greatly appreciated thank you .

Can't think of anything specific. Probably someone might be along shortly. But I would tend to first of all look at the usual suspects. See if one of the HT leads is shorting (run it in the dark, see if you can see any sparking anywhere) and check the battery terminals are not loose. These days spark plugs seem to last a lot longer than they ever used to, but that's another avenue to look at, compare the state of them, which might give you a clue which cylinder might be missing.

Thank you for your input I will start her up later in the dark I originally thought it may be  fuel pump related

So checked the spark plugs all good no blue flashes run her up in the dark she starts no problem and there is no missfiring until warmed up

If the FI light has lit, even for a moment, then the PGM-FI system has noted an error.  It should have stored a fault code which can be read from the system.

These systems can't read HT outputs so, oddly enough, it is less likely to be coil/lead/plug related even if they arent 100%

Reading the code/s is key.

Thank you I will look into that as the problem is likely fuel-related I assume rightly or wrongly ?.

To clearly answer one of your original questions/suggestions, your problem has nothing to do with using 5% or 10% ethanol fuel. Rest assured that the bike runs on both quite happily.

If the Fuel Injection (FI) Malfunction Indicator Lamp (MIL) is flashing I'd start right there because when it flashes it is flashing out a fault code, or if its on constant its an indication of a stored fault code. You don't need any special tools to read the FI MIL fault codes click here to read how I do it

Thank you guys for all your help and advice I have managed to locate the problem there was no faults on the MIL so I had to look deeper and I found a moving  positive pole on the battery it was loose but the connection to the battery was solid  so fitted a new battery and hey presto it is all back to normal
