    Ok away from my previous threads and onto something more triumph serious, I have a 2011 T100.
    On a few occasions when wheeling the bike out of the garage having had the battery on charge for couple of weeks, when I press the starter button she sounds like the battery is flat, but... persevere and she eventually will go. the previous owner told me about this so expected it..
    My point is I cannot believe I am the only one who have this slight problem ???? never encountered this other bikes I have owned. Is there a fix for this does anyone know of.
    Thanking you all.
    Mallywoods.

    Have you checked the wiring and connections? Any dirty or loose connections? Is the main fuse clean and firm?

    Are all the connections to the battery, starter etc tight and corrosion free. Do you have a multimeter to check what the voltage is across the battery when you press the starter then again on the starter to see if the power is getting through. Other than that I can't help.

    Another thought-did you change the battery/were the same symptoms there with the old one. If they were then it sounds like it's not the battery

    Does it do this every time or do the symptoms change slightly?
    I’m just thinking it could be a faulty starter solenoid, or even the starter itself.
    As littleade says though, a good clean/ check of connections from the battery to the starter would be the first steps.
    Good luck with getting the problem sorted.

    Not being a T100 owner I can’t say that it isn’t a quirk of the model, but being an engineer makes me think there is a problem if it’s not working as it should be expected to. :confused:

    I’d say there’s a problem. Give us a clue! It obviously has been happening since you’ve bought the bike but was that 3 months ago or pre your new battery? If you can’t hook your bike up to a known good battery and see if it still happens then, as said above, give everything a good clean up and check

    What are the symptoms? Does it just click pause click pause click etc? If so is it a fast series of them or is there a good full second between the clicks? If you run a test wire directly from your positive to the starter solenoid (small tab) will it turn over successfully?

    Yes your right click pause 3 or 4 times then the engine turns, sometimes the engine turns on the button first time.

    If you get a click it sounds like a bad connection from the solenoid to the starter motor or a bad starter motor but could also be the solenoid change the cheapest parts first

    I have a slightly more mature T100. With a healthy battery it has never hesitated. Your intermittent symptoms smack of a poor connection (earth strap stud underside rear gearbox?), lazy relay etc. I would squirt the fuse box and multiplugs (don’t forget inside headlamp shell) with electrical cleaner (Halfrauds aerosol) and wiggle. At nearly 10yrs old you can reasonably expect mild corrosion and the odd tired component.

    I had this problem on my Kawasaki. Corroded contacts on the starter button. :)
