| DD bike doesn\'t start
New exhaust fitted, yesterday I wanted to start the bike just to hear how good it would sound...
The bike hasn't started during the winter, so I bought an Optimate 3 to try and get the battery fit.
But even with that, the bike doesn't want to start... When I press the "start" button, I can hear the engine doing 1 rev and stopping, just like if the battery wasn't strong enough, even if yesterday the Optimate was was saying "good" regarding the battery health...
So the optimate is still on the bike, will give it another try tonight. Any idea? Does it mean I have to buy a new battery? |
