    amauri, I checked the auto shops for 12 gauge here in Oz and I just get blank looks, so I googled 12 gauge converted to mm & it says 2mm is equivalent to 12 gauge ? 2mm wire seems thin for the job, am I missing something ?

    I had a similar problem with comparing gauge / mm. Found some wires 12 gauge on eBay, you could give that a try?

    12 AWG as an add on to the existing wire is fine. You are just adding more copper to the circuit, thus lowering the overall resistance. Think of it as adding 2mm to the diameter of existing loom wire. It's not really as straightforward in real life, there is a formula to clalculate the exact value, but basically same logic applies. As one of the previous posters noted- adding an even thicker wire would be better electrically, but as Amauri stated- a lot more difficult to install due to terminal size on solenoid.

    Ok thanks, just checking that 2mm is equivalent to 12 gauge, just seemed small compared the the pic amauri posted.

    Ahh,it's not equivalent to 2mm squared.
    it's one of those in-between sizes.
    2.5mm squared is 17% smaller in area.
    4 mm squared is 33% bigger in area.
    In the US, a unit known as "Circular Mil Area" is often used to describe electrical current carrying capability.
    Or, we use the really archaic and confusing AWG system.
    Using the metric system makes a lot more sense (in this case).

    12AWG wire is 2.05mm in diameter.

    The AWG or mm˛ or diameter in mm refers to conductor size. Wire sheath or jacket thickness or overall size of jacketed wire could vary widely based on a lot of different factors and specific purposes for that wire.

    I haven't disconnected the battery before, should I expect it will throw any faults ?

    Spent my day after work adjusting clickers all round by 10 in here and there, not one to muck around with a turn of one or two, even if some only have 3 turns, running some dunny alpha Q3's at the moment, stick alright, catch up ya dog,

    If you go to any auto parts store, the 12 gauge wire is sold as "primary wire".

    Hi All,
    I too had a couple of hot start issues occur with my RSV4 13 Factory.
    I had the fairings of one day and noticed how close the exhaust headers are to the starter motor.
    So i got to thinking and came up with the below fix for me.
    My bike regularly sees the temp hitting 104C, as its currently 38C average daily where I live.
    The below pictures hopefully say a thousand words.

    Before image, showing how close the Ti Akro Race headers actually are to the Starter Motor:

    Header reinstalled. and wrapped in Ti Thermo Wrapping aswell.

    I've only done a couple of short runs with the bike, maybe an 1.5hours atmost. I had 2 hot (relatively) starts on the ride, and there was no issue.
    As an aside, the Ti Thermo Wrapping on the headers has seemingly reduced the engine operating temp by 3C (degrees Celcius). It also assists the radiators in flushing the hot, latent air normally trapped between the radiator and the front of the engine, as the air temp here has been reduced. Now when the engine temps gets up over 100C, it is now quicker in flushing the hot air out.
    I have yet to wrap the rear headers, but hope this will help reduce the temps that the fuel tank and my nards see.

    Makes sense if your starter is getting cooked to protect it...
