Bike won't start in the cold - SV650.org

17-01-12, 10:33 AM

Right last week and today when it's been proper cold the 99 sv650 won't start.
I had a new battery in October when it was cold, as it was doing the same.
Since then it been starting and running fine, until now, I have tried starting it with the lights off but it just keeps trying to turn over but won't fire up. Now it won't as it sounds like the battey is flat.

What's the way to go to get it sorted???

Find out why the battery is going flat.When you replaced it last time did you check the charging system to find out if it was ok?If not best do it now before spending hard earned on another battery.Does the bike get regularly used for longer trips or does it have a trickle charger to keep the battery happy?

Curvies do have a tendency to kill the regulator rectifier. As said above, check your charging system

Fill it with super unleaded. My old curvy used to have a so-so battery. When it got cold I had a 50:50 of it starting in the mornings and if it didn't start straight away it didn't have enough oomf to turn it over long enough to fire up.

Switched to super unleaded (esso or Shell) and it started on the button all through the winter on the same tired battery.

May just have been a coincidence but seems my 125 scooter (carbed) behaves the same way when cold.

Yes fwr in vauxhall checked the charging system and said it seemed ok but if I had problems take it back.
But it sort of warmed uP and had been fine.

I have been using 97/98 Ron petrol once in a blue mOon, I'll try that in the future

If the charging system is good check all the connections are clean and sound,especially the battery terminals.The SV needs a lot of battery welly to turn the engine and start up especially in the cold.Any poor connections will drain some of that welly from where it needs to be.Also make sure the battery is kept fully charged by going for longer rides and putting it on a trickle charger from time to time.

i think about 15 minutes of riding is just to replace to power you took out the battery from starting, anything less will just slowly start to drain it out.
