Another good idea of mine whilst we had the snow was to use my little brothers mini moto, it has alot more power then my bike and a thinner back wheel, a recipe for wheel spins.
So i took his bike out and pulled the pull start. I spent around 10 minutes trying to start the bike but no joy. I believe that this is the spark plug aswell.
I am going to have to replace all the spark plugs in all of my bikes and the scooter with new ngk spark plugs. Hopefully this will solves the problem as at the moment now of the three will start.
I'll let you know what happens when it happens.
