Hi Terry,Thanks for doing that test and the info.
I have a fairly new digital battery load tester so just i tested the 1 yr old Deka AGM battery that prior owner of my bike installed before i bought & it showed as having 525CCA even though its a std repl YTX20L-BS battery that supposed to be only 275CCA.
But since the air temp & battery was approx 75-80 deg when tested thats why its showing more CCA then if the batt was actually at o deg f temp where a batteries true CCA is tested at & not at the much warmer 75-80 deg temp it was tested at.
So the Yuasa thats rated at 310 cca came in at 542CA at room temp which makes sence,the odyssey comming it at a weak 363 doesnt surprise me at all,going by its design spec even being 1yr old it should do a lot better then it did . I was never that impressed whith that type design battery but it does have its place in some appas,thats for sure. But IMHO
the Odyssey batt isnt the best choice for a R* for reasons i stated earlier in this post.
Maybe you can hook the original poster up with the slightly smaller batt he's looking for that will fit/work with the mods he's making to his R and still have enough umph to start it esp when the starter & motor are is all heat soaked in hot weather.
If he hasn't done so already he should also consider removing the very small /thin guage stock battery cables and installing larger ones for max current flow to the starter if you guys @ Phatt perf have them avail.
I already did the mod to my 06 R* and it now spin's over a bit faster cold & hot.
The stock battery cables on the R* are slightly smaller then the batt cables on my riding mower with a 10hp techumseh ,something's wrong with that picture,thats for sure.(LOL!!)
