    Has anybody had problems with the FI light coming on and cutting out ? Just started today , so any advice greatly appreciated It's cut out on me three or four times on way home , pull clutch and it will start on the button set off again , and it's starts playing up again
    Cheers Tony

    Not an expert on this but as nobody else has responded - the sidestand switch has been known to cause problems and I wonder if there is a switch in the clutch lever as well?

    HOWEVER, depending on what model you have it may be the 'loom fix' problem - see the sticky at the top of Help. Either way, if your bike is one that falls into the loom fix category you should do it anyway as a preventative measure - it will most likely bite you in the bottom at some point.

    Keep posting, someone with more knowledge than me will have the answer.

    Cheers Andy thanks for the prompt reply , I will study the loom fix and carry that out and see if that cures it It did seem strange when the engine just cut out , and while coasting, you just pull the clutch in fire it back up on the starter , and dump the clutch and away again , till it played up again

    It did make overtaking nerve wracking though

    Just a heads up - you have ten 'free' posts on this site - after that you need to be a sponsor. Hopefully the advice you have already received will be worth £5 ".............

    Upgraded well worth it :) just been for a ride on it , it's an 05 by the way , light came on three or four times , but no loss of power this time , strange but will carry out loom mod and see if this cures it

    I helped a mate check out the loom fix on his bird a couple of weeks ago, it had already been done but badly & he was having exactly the same issue, a bit of snipping & re-soldering & all has been well since so going from that alone I would say its the first place to look

    As for side stand & clutch switches I remove them from every bike I own as a matter of course whether they currently work or not because they always seem to cause problems, doing this isn't for everyone especially if you are daft enough to pull away with the stand down but never having had a switch I don't have a problem remembering to kick it up ......... its better than a stutter or worse cutting out mid bend IMO

    Welcome to a new sponsor

    Sounding more like a 'loom fix' issue by the minute - essentially there is a test plug in the loom that connects multiple earths together, they corrode and then, voila, no earth. Sheer genius.

    I agree with Andy that the loomfix is the logical place to start.
    Most FI light problems seem to be linked to this. Please make sure you use a fecking BIG soldering iron and using extra flux rather than just the flux in the solder core helps a lot. Flux and bar solder is available from a plumbing outlet. In the unlikely event the problem continues after doing the loomfix we can move on to more esoteric solutions. :rolleyes:

    Thanks so much Andy , Slim and Centaur for the help , I'll take it apart tomorrow afternoon and see if I can find it :) a mate of mine is pretty handy with a soldering iron so I'll get him to solder them , hopefully the end of the problem , I'll keep you informed , I believe it's a yellow plug for an 05 model reading the post on the forum :)

    Good luck, Lockey. Please just make sure there are no dry joints or you will be back to square one. You need to be certain the soldering is good to move on if the FI light comes on again after the loomfix is done.

    Cheers Centaur , I've got some copper stop ends different sizes , I was going to tape the wires together then fill the ends with solder , shove the wires in until set , hopefully this does the trick

    Sounds good, Lockey so long as there is plenty of flux and heat.

    Just a quick update , finally got round to doing this , and it all went great , soldered all individual wires , then filled a copper stop end with molten solder , put them all and left to cool , taped it up with the rubber tape stuff , good as new :) took it for a 100 mile test ride , and I'm sure it seems to run even sweeter than it did before , so thanks everyone for their input , it's back to being the best bike in the world again now

    Hi fine folks I've done about 500 miles since I did the loom fix , this morning coming home from FI light back on cut out and hiss light too this time lost power , managed to start it and get home , do you think it could still be a dry joint in my soldering , or have I damaged something else while I had the problem ?
