I've gotta agree with you on that, Steve!! :agree: . And if it's a V-twin with a magneto type charging system (yeah, I know - well, I
think anyway, that yours
isn't one of them acdcking...but for those who
DO have V-twins...

) then short runs like that probably won't be enough to keep the battery fully charged either!! :banghead: In fact, even if you
DO run a battery tender whenever you aren't actually ryding, frequent short runs like that will
still probably be significantly reducing the potential life of your battery!! :shocked: Besides, running any machine
only for periods that short will really be concentrating all the damaging aspects of 'cold starts' and delivering none of the benefits of regular running!! :gaah:
Even the 1330 triples with their alternators will benefit from a longer run a couple of times a month for a variety of reasons - 30 mins or more averaging 'mid or above' revs will help get everything properly warm so it can 'evaporate out' all the condensation that collects inside the engine etc
AND stirring the oil up, heating it, & properly circulating it thru everything will also go a long way towards stopping it congealing in those little tight spots you don't want it to and also burning/boiling out any of that previously mentioned condensate & a bunch of the other nasty contaminants that get absorbed into & build up in the oil over time, especially during periods of frequent short runs; plus it'll help give the battery a reasonable chance of charging fairly close to full charge in the time it takes to do those longer runs, even if it's still not long enough to completely/fully charge it up; and running it long enough to achieve a 'proper warm up' as well as rotating/using everything that should be rotated/operated/used will help keep all those bushes & seals & bearing/wearing surfaces in good nick in a way those 2 x 15 min runs per day just can't - and the longer runs with their associated 'wind therapy' plus the physical exercise they entail will help keep
YOU working properly too!!

hyea:
I'd go far as suggesting that those 2 x15 minute runs per day actually equate to 'hard use' as far as everything is concerned, especially the oil - so that sort of usage warrants a more frequent/shorter milage oil & filter change schedule than the 'normal use' schedule detailed in the user manual! :lecturef_smilie:
