    Nice! Those teflon-tipped little solder poppers are quite handy. I just wrangled the original one apart, Deefred, and quickly realized I should have desoldered, as there was plenty of "meat" in those contacts left.

    Wonder why they are so "derated" to 50 Amperes, as that's a pretty ridiculous number, considering I have Bosch relays rated at 50A with no more than a 1mm contact circle.

    If you are going to put this much effort into the solenoid then also put effort into replacing the battery/starter cables by upgrading to 4 gauge cable.

    Here is link http://www.triumphrat.net/speed-trip...power-mod.html

    Yes its Triumph related but I have done this mod to Triumph, BMW, Ducati and April. To me well worth the $$ and time.

    No sense making the spigot bigger/better (solenoid) and not the hose (cable.)

    Cheers

    A lazier, cheaper option (always appealing to me) is running an extra 10awg wire to everything starting from batt, including an extra ground. Works pretty well. I've also got the F150 solenoid. Make sure you clean all connections and grounds.

    Done pretty much the same now with larger cables from the battery through to the starter. Also added larger earth to chassis & engine.

    I did notice that the throttle bodies are not earthed?? - any reason??

    I'm sure I remember being told or I read somewhere that adding a decent earth to somewhere near the injectors (this was on a car!) would give an improvement in running. Not sure if that was meant to be on economy or power?.

    Anything in this??

    Do the injectors just have 1 wire? Everything is controlled on the ground side of the ecu, so I'd guess there are 2 wires to each injector. If that's the case, then why both ground the TBs?

    Correct, two wires to the injector.
    The injector is encapsulated in plastic, so grounding the TB does nothing.

    There might be something to it. I've done this on a Buell... the earth for the engine to the battery went through some painted subframe bolt points so it was always pretty poor. Ran a starter cable from the top engine mount right to the battery and got better starting, smoother running.
