Battery Cable Upgrade
I've always thought my bike cranked a little slow, even with a hot battery and new starter. I was thinking it might help if I put heavier battery cables on it. Can anyone recommend a heavier direct replacement?
Edit: Also, I believe the stock cables are 4 gage. I was looking at some Sumax 2 gage and was wondering if the can be installed without any modifications. They say they are "fat". Anyone know.

AWG...the correct gauge is all you need to know. Most important other than that is keeping the everything clean from oxidation.
Edit: AWG and ampacity

I'm looking at the 22007. Looks like the right thing to do, but I'm concerned about fit problems due to the overall wire diameter. One thing I really like is it's got the top mount cable lug. The straight lugs on my 07 heritage are a pita since they mount in the front of the battery and there's no room because of the wiring harness.

I'm open to other suggestions if anyone know of something better..

What does the manual say it recommended battery in amps? More battery is better, too much is overkill, gauge your wiring according to the stats. *ie, I needed a cable that had a load of max at any given time of 115 I would consider that borderline and go to the next size.

I'm not sure what the specs are on the battery or the full load draw of the starter. Haven't been able to find anything on either. But, based on the link you provided 6 gage max amp transmission is 37 amps which is way low for battery cables. The problem is the table is for solid strand wire, not multistrand. Theres a big difference in behavior and load capacity.
Edit: I think I'm going to go with these Terry Component cables. They are 4 gage which is quite a bit larger than the OEM. If these don't do the job, I'll go with the Sumax 2 gage. I'll let you know how it works out..

I installed the Sumax 2 guage cables, a new chrome 1.8kw high torque starter from DB Electrical and a new 310cca agm Duralast Autozone battery all at the same time on my 03 Heritage.
It has did really well ever since. The Sumax cables are really nice and did fit well without a hitch. $50 and the shipping is a pretty good buck to pay for battery cables but it is nice to be able to bolt them on without any problems and know that your battery connections are nice and fresh, not corroded and won't heat up at start up from being to small.
You might save some money elsewhere but, these are heavy duty cables that are made to fit and they do just that. I don't have any regrets.
