    That battery should be plenty for that bike. You said you "checked" the cables, but did you take off the leads (negative first), clean both mating surfaces on each lead with a wire brush, and reinstall (negative last)? Also, did you check that the lead on the starter was tight (might take that off and clean as above)?

    Do you have a VOM? Check the voltage across the battery terminals BEFORE you try and start it next time. Should be at or over 12 volts. If not, and it is under 11 1/2 volts, your battery is not getting fully charged by your alternator, or you do in fact have a current draw. See here:

    Cold IS hard on a battery. You might want to consider a tender. See here:

    Another potential option could be thickening or too thick of an oil selection for the temp. How cold is a "cold start morning?" Perhaps maybe a 15w40 or 10w40 may help if your cold starting temps are under 40 degrees. This is assuming that the battery is in good shape (which it may not be!!), there's no or very little voltage drop from battery to starter and the starter is not worn out and just lugging.

    Anyways, welcome to the forum!! You will find a HUGE wealth of knowledge here, and some VERY knowledgeable people who all want to help each other. Let us know what you find.

    If you have a meter (DVOM), connect the leads on to both ends of the cables one cable at a time while they are still attached to the terminals and set the meter on 1K ohms resistance. Crank the bike with these meter leads attached and see if the meter registers anything. It should barely register. If it does register any significant amount, there's resistance in that cable and it should be replaced.

    OK. See this below. Same info as Glider posted above, but with link to very good looking cables if you find you need some. I wish my bike looked this organized under the seat!!

    Crank the engine when it turns over slowly until it starts. Shut it off then as soon as it starts and feel for a hot terminal or cable to see if there is resistance in any of the cables/connections. If there is you located the possible source of the problem.

    Two things, point the bike so the headlght beam can be seen while starting...it should dim only slightly while the engine is cranking prior to starting...if it goes to less than 1/2 brightness or goes out, you likely have a weak/dead cell or the cable resistance of one of your heavy battery cables and or starter cable is high.

    You will feel one of the terminals warm or hot to the touch, but really you should remove all of them and SCRAPE them till they are shiny, coat with dielectric grease and reinstall. If a cable is hot, it is probably one that is bad.

    If the cable is good, it shouldn't get hot. It is usually at the ends of the cable where it gets hot indicating a bad conductor within.
