Dave you could be onto something there. Is that cable accessible in any way "IF" that looks like something to try and change ? Does anyone know if this bike bas a starter rely of any kind that could be a power draw ?Ya know, ya got me thinking which is NOT a good thing!! lol lol The only thing I haven't checked [shame on me] which I just thought of, is the available voltage passing thru that heavy battery plus cable to the starter.Tomorrow,if I can remember,duh!! lol, I'm gonna check that.Why?? Cause it's also possible that the cable running from the battery plus to the starter is too small.In other words,when it gets cold,the gauge of that wire can not carry enough amps to the starter to crank it over fast enough.Follow me??If you have a volt meter,hook it up to measure what you have.I'll try to remember to check mine in the morning cause tomorrow is supposed to be a decent day.Dave!!!
