    Advice?

    My 2014 Heritage seems to have developed what appears to be a minor gremlin.When I re-start a hot engine after a brief stop, it tends to make a loud klunk before kicking in and turning the engine over but then starts ok - however, the readout on the speedo re-sets to the total miles to date from whichever other setting it was on, and scrolling through the options it shows that I have low range left in the tank, when it clearly has plenty fuel in.Once it's cold, it starts fine and the low range reading also disappears.I've not looked at the error codes yet (t.b.h. I don't even know how to yet) - any ideas?

    When you say loud clunk, is it just when it overcomes the first compression stroke. If so it could just be a case of a low battery voltage, that would also give the erroneous speedo readings as the trip counters would reset.

    Quickest way to check is to start it using jump leads to another battery. If that cures it its the battery or charging system.

    Start with the easy, cheap things first. Clean up the battery terminals & the wires that connect to them & make sure that the earth lead has a good earth connection to the frame, don't rely on the bolt. If you have several wires to the battery terminals, then connect the main wires up first & any accessory wires on top. This way, the start system will get max possible output from the battery. As Gizmo said, the battery could be on the way out. HTH.

    i'd go for the battery as well mike. easiest thing to check first. a low battery can throw up any amount of codes and also give the clunk you're getting.
    there's a post on the 'help with error codes' thread just below this one by les 049 that links to how to read and get the codes up.
    good luck.

    Forgot to say that it's not every time - tonight for example, no problem at all other than the slight pause before deciding it wants to play that it's had from new. I think this is the one you're on about while it gets over that first compression stroke. The one I'm on about is more like a hammer blow would sound like - that's about the best description I can think of. Battery is always on a trickle charger at home but I suppose it's nearly four years old now, so could be - I'll look into that. I'll also take a look at the error codes thread, thanks for that.

    Not checked out the battery yet - however, I used it for a 500 mile charity trip last Thursday and it performed faultlessly throughout! Then used it for work on Friday and it did it again when I got home - switched it off to unlock the gates and garage, get my gear off etc and there you go, same thing again! Will see what happens when I start it up ready to go to tonight's meeting. Wondering if it's heading the same way as Daz's bike on another thread he's started about overheating?

    Ok, so took the bike to the meeting last night and the whole way there (only 8 miles) the display showed "Lo Range" and low fuel warning light was on, though still working perfectly. My plan was to re-fuel on the way home anyway, but when I started it the "Lo Range" corrected itself to read 27 miles remaining - didn't bother with the fuel and just went home to fill up when I use it for work tomorrow.I did however notice that the light in the display was initially only half lit up, then went off altogether and then was fully lit up by the time I got home - can't imagine for one minute that the two things are linked but did seem odd!

    I had a problem where the fuel gauge read empty, the warning light was on and it was traced to a 2 pin connector under the tank which comes from the sender unit to the ECU. The tank could be lifted up a bit with a small wooden block which gave access to the connector. The local Guru had the right connectors and we remade both parts all ok now.

    Cheers Tom, noted. It should have a good test over the weekend, although only doing some 400 miles over the two days, I'm "escorting" a load of mopeds/little/classic bikes on a coast to coast, with lots of stop/start stuff - let's see what happens with that combination of low speeds, high temps etc.
