    I have a 2005 Bourget with a S&S 117
    I’ve always had cold starting issues with the bike as the season starts to get colder Even with compression releases hard starting. I’ve tried everything from changing batteries to warming up motor with a space heater before riding.
    I ordered the YTX12-20 with 600 CCA
    I was amazed at the batteries light weight
    So far I am impressed. The battery actually gets stronger after the 2nd and 3rd turn of the key.
    Hopefully problem solved
