All.

So new season , health back to normal ( heart scare wasn't heart) and I thought it would be good to get the bike out.

Washed it, charges it , put new fuel in and started first turn ( as usual ) , took it for MOT , passed with minor advisories RESULT !
Then pulled into a pub to buy tax online and went to start it again and it wouldn't start. FI was lit up :( .
Breakdown came and put some jump leads on it (I had killed the battery by then) and away it went :) . Wrote it off to spending a winter in storage and possibly the washing it .....

Later in the week went for a 50 mile run , all good except just for 1 second , I lost power then back to normal .
still good.

Next day took it to work and at end of day, the FI was back . Grrrrr.
I got the code C41 from the dealer mode thing and need to know what I should test first.
Any people with this fault? Is it Common?
Any help would be appreciated.

Cheers

Thanks. Will spend my lunchtime pulling bits off . I think there is some talk of battery being slightly too weak ? So will start with jump leads

If you hear the pump prime when you turn it on the relay must
be working at that point at least.
