First: I'm not against running a $200.00+ battery. For those that have an Odyssey in their 1300 and are happy with that - GREAT! No question it's THE battery to have. Just want to make certain I'm not offending anyone before I continue! So:
I'll never deny I've had my issues, as we all have. When I rolled the bike into my shop last year to sort out some hard-start/rough idle concerns I had a web-site up and running and was ready to order an "Odyssey" battery. My personal experience as with others was if the bike didn't start within the first few seconds - it wouldn't start at all on a cheap battery and my cheap battery simply didn't have the reserve-power to do any more. The thought was(is by some): If one has a higher capacity battery it must start (eventually), right? Not necessarily! Attempts at "boosting" proved this a fallacy in my case. It still would not start. As I have discovered in the past also, endless cranking-over created problems with my starter-solenoid not to mention the wear and tear on the starter-motor and the starter-clutch! So I decided to check-out some carb.-idle-circuit concerns before dropping the coin on an "Odyssey". The time taken to completely disassemble and clean the carb's (several times!) proved worth-while. As we have all heard countless times ( from myself included - CLEAN the CARBS). The difference is remarkable! I submitted a fuel-line mod which I did last winter at the same time. Having an insulated tank-bottom and strait-forward simple fuel delivery is of enormous benefit too, especially on hot days and removes one more issue from the equation. ( along with "coils" and some of the other "standard" fixes.
So as far as batteries go: I'm running my 2nd year on a "Wal-Mart" $69.00 battery and the bike starts with no choke at the touch of the starter button - every time.
My point is: If the bike won't start easily with a cheap battery it is worth while dealing with the real problem(s.
