    2007 Triumph Speed Triple Not Starting

    I bought a 2007 triumph speed triple not running. Problems led my to thinking it needs a new stator so I put a new one it and that didn’t work. I put in a Brand new battery and 3 new plugs. The right and middle plug had spark but the left one seem to struggle to make spark. I took the starter out and it spins and seems okay. I took the rectifier out and I’m contemplating buying a new one to see if that will fix it. The battery with the key on reads 13.1 volts and drops to about 10.3 when I try turning it over. I’ve attached a video of the sound it makes trying to start. Rectifier? Starter? sprag clutch? Bad cylinder? Please help!!

    You don't need a functioning charging system for the bike to start as long as the battery is fully charged. Cranking sounds a little slow but if you ran the battery down a bit cranking before the video that would explain it. Sprag sounds OK but supposedly cranking with a low battery can tear them up. I'd replace the coil with the weak spark. Is it getting fuel? Do you hear the fuel pump run? Try a little starting fluid and if it fires and dies then you know fuel is the problem.

    Sounds like a sprag to me, I'd change the rectifier too.
    Anyone seen my 10 mm wrench?

    It’s getting fuel but it just doesn’t seem like it has enough power to make it turn over. I think I may try to throw a new rectifier in there and then see from there. Also may try bump starting it.

    Like Dr_Gallup said, if you've got a fully charged battery it isn't your charging system (although I recommend replacing the regulator with a series type anyway.)

    If your battery is okay and everything else seems fine, I would try replacing your starter solenoid. If it has got wet and corroded inside it might not be sending enough current to the starter. It also might be the starter itself, or the wire between the battery, solenoid, and starter. Or any of the connections.

    Also, if your regulator isn't bolted in to the frame then you may not be getting a good ground connection. Bolt that damn thing in before trying again!

    Visit this link to review the good battery for bike.
    I think the spark plug is also a cause if it is dirty or loose. You try to check it.

    Had a similar fault with mine, battery voltage good,measured between battery earth and solenoid output,6 volts! stripped starter motor and one brush was nearly
    gone and commutator a bit burnt, and high resistance across solenoid, toyota mr2 electric steering motor solenoid is the same but heavier duty, brushes are cheap,
    comm will clean up,you need to check voltage drop and earth integrity with a multi-meter, but they are prime suspects,my starter seemed quite fast, but had no torque, good luck.

    Did is sound the way mine does when it tries to turn over? I spun real fast and well when it turned it while it was out of the starter clutch casing

    Yes mate,free of the engine starter motor speed was good and voltage drop was minimal, put it all together and on cranking voltage drop was huge and
    cranking speed was slow and laboured, not a way in the world it would start, did with a tow up the road in 4th! depending on ecu some won't fire unless the
    starter buttons engaged whilst attempting a bump,check it thru with a meter rather than throw bit's at it !
