Please please PLEASE don't. Imagine the scenario, your steadily pootling along, minding your own business, minus the front cylinder, it's cold out, possibly ice on the floor. All of a sudden, mid corner whilst you're holding a steady throttle, the front cylinder kicks in & there's a massive serge of power.

About the battery, as above, this could be a number of issues, and until you're certain, it's not really wise to buy a new battery. For example, if the Reg/Rect isn't charging properly (due to a fault itself, or a dodgy connection), a new battery would be money down the drain.

Probably not long term. Cold weather = hard work for battery when starting. Check the charging cicuit like already suggested, if OK then get an optimate and plug it in over the weekends, topping up the battery to full charge. Optimate are great, as they condition your battery and also tell you when it is nadgered.

Thats about right. Do a google search for bike batteries. Mike1234 gave me a link once, but i dont have it anymore.

I got one of a mate 'trade' and that was still £25.

There is also the possibility of condensation in the carbs. Especially when you are only running it for 15 minutes. This would mean that just as the bike is getting warm, you are switching it off again. Ideal recipe for condensation. Also there is a possibility that condensation has developed in the fuel tank.

Water is heavier than petrol, with the bike on it's side stand over the weekend, all the condensation (water) will have time to find it's way to the fuel outlet on the left hand side of the tank. The 1st thing that you do on a Monday morning is turn the engine over and let the water that has collected go straight to the carbs. This along with a weak battery, short miles riding would be a perfect recipe for a troublesome starting bike in weather like this.

There are several ways to avoid this. Ride your bike during the weekend.

Keep the fuel tank topped up on a Friday before putting it away for the weekend.

It is possible that continued riding will force the collected water through the jets and sort of self clean itself. However, there is also the possibility that a complete drain and flush could be required. Tank and carbs. I have just had to do this myself. Should only take a hour or so.

Of course there is always the option that I am completely wrong and taking balls as usual.

The SV battery is more expensive than some other bike batteries of the same capacity due to the fact it is a sealed gel type. It needs to be of this type due to the fact it dosen't sit level.

wicked, a thread already on the subject of what i was gonna ask.

heres the situation.

my bike (CBR600) has had its battery in it since new nearly 6 years ago.
all has been fine with it, sunday i started it in the morning, rode about 2 miles to a petrol garage, filled up with petrol, tried to start the bike, and the battery died, a gave it a few mins and a good shake and pressed the button, it just about started,
then rode 60 miles and plugged the battery into a trickle charger,
the charger told me that it was fully charged,

disconnected the charger, started the bike fine, killed it again and reconnected the charger, took a few mins then came back and told me it was fully charged.

rode the bike home 60 miles no problem.
any idea's on why the battery died at the garage ? surely if it was going to die, it would have died when i tried to start it first thing in the morning ? and the 2 mile ride would have given it enough charge to start at the garage.

im not sure if it has anything to do with it, but a few weeks ago i fitted an inforad gps speed camera detector to my bike, which is turned on when the ignition is turned on as it is wired through the rear brake light switch. so am i correct in thinking when the ignition is off, there is no way for the GPS to draw power from the battery ?

does any of this sound normal ? or not ?

im gonna get my multi meter and check to see if the battery is ok,
can someone give me an idiots guide how to test the charging ciruit and stuff ?

before i splash out on a new battery.

ive disconnected the GPS thing by the way today, so see if that helps things.

cheers

Due to unfortunate circumstances, it's often a month between rides for me on my SV which often results in the battery being dead when wanting to go for a ride.
This happenned a few days ago, so I charged the battery overnight (real trickle charger thing so no danger of overcharging). I then tried starting it in the morning but only suceeded in draining the battery in 2 minutes of trying to charge the battery. I assumed I'd have to buy a new battery at this point so in an act of desperation I cleaned the battery connections with emery paper and put a smear of vasoline on them.
When the battery came off charge it turned over without any issues (started second time).

So try sanding down the connectors down to the bare copper and put a smear of vasoline on them before forking out on a new battery.
