Was recently doing some self servicing on the bike and decided to get a new battery for it since the old one was well, old and wasn't charged. I would have charged it but I thought that I may as well just get a new battery for it and charge that one up like yeah I had money to waste and a tonne of it so I bought a shit load of stuff like muc off, new oil, got a new rear tyre because the tread had gone on the other, new brake shes for the front and rear, a headlight - lamp upgrade and so on. I had also finally got the time to put my panniers on and top box because over the Christmas period I plan on doing quite a bit of touring around parts of south Wales regardless of the weather conditions Right down to the deal! I put the new battery in and connected it up, installed the new light builb, fitted the new rear tyre and brake shoes for both brakes, changed the oil and cleaned & adjusted the chain. Now when I tried starting the bike it simply wouldn't start, it would try to but wouldn't. I thought for a moment or two over what the problem could be...There is petrol in the tank, the battery was connected right, the light builb is the correct wat/voltage. At first I thought it was the spark plug but then I had changed that last week. Can't be the oil because its the correct type/stoke oil. I have hit a damn here folks, I have no idea what the problem could be. I've tried priming it as well but still doesn't work and the bike is in neutral when I try to start it. Any ideas?
