HI all

bike stated to have problems starting i the cold mornings.
bike was hooked up to trickle charger this wknd, so i could use it come monday.

tried starting it this morning and it seemed as thought the battery didnt have enough power in it to start. (so i used the trusty golf GTI)
this afternoon presuming the battery had died on my (as i had this problem last year, replaced battery and regulator) bike i thought i would just give it a try and wow to my amazement it started the first time, i didnt do anything to the bike or battery all that changed was the weather ??

if anyone has suggestions what ould be wrong im all ears.
battery voltage 12.57 volts (im going to take it off the bike and charge it for 24hours see if the voltages drops in 48hours of been disconnected )
regulator was chargeing between 14 to 18 volts on idle.
bike is a sv650s 1999 (carbs not fuel injection)
oh and if anyone can recomend a good oil i can use im doing a service on it this wknd. (would i be able to use a synthetic oil or part synthetic oil from halfords ? i got a trade card so cheaper 4 me)

look forward to your replys
