I have an Odyssey PC680 in my VMC 2332. It starts fine cold. However, once it’s warmed up, it sounds almost like it’s binding. It’s similar to a car with a weak ground. What can people recommend? 170 CCA is not a lot. I’ve thought of adding ground straps, replacing cables with 1 gauge, relocating battery, researching second solenoid.
Thoughts?

I had a PC680M in my Speedster with a 1915, and it always cranked quickly, cold or hot.
Are you sure it's your battery?
Batteries don't "bind".
I've used a PC680 on a 2,110 at 8.6 compression ratio for over ten years with absolutely zero issues.
I would check and clean all of your ground cables (battery to chassis, chassis to transaxle, transaxle to engine ground braid (if you have one) as well as both ends of the +12 volt cable (battery end, starter solenoid end) so that they're all bright and clean and firmly torqued down. The other place to look at is both ends of the starter circuit (fuse panel to ignition switch, then starter switch to the solenoid). Another thing to consider is the voltage drop along the wire between the starter switch and the solenoid - using too small a wire for the current or high resistance connections can starve the solenoid of power of engagement power making it weak.
Lastly, your alternator might not be charging adequately so you can check the voltage at idle and at, say, 3,000 RPM to see if it is up to snuff.
If that doesn't make it better then you can begin to look at the solenoid or starter, but those failing is rarely the case.
This came up earlier and someone suggested overheating starter. My Spyder used to act like it had a dead battery when it was hot. Let it sit for 10-15 minutes and it would start fine.
That could depend, also, on the age of the starter. Some older VW starters would act like that and I suspect it was from dry bearings in the starter. Pop in a new starter and it would spin right over.

Mine did that too. Usually on a hot summer day, and after refueling. You know, when everyone is looking at the "funny little car"? It was heat soak.
I replaced the Bosch SR15 with an IMI-101 and NEVER had a problem again.
