Hi Jeremy.
I've pulled the starter out and spun it over on the floor, it worked great. I've also checked the earth on the front right of the engine and it looks good, I'll take it loose and clean it tomorrow. The battery I bought new from a reputable bike dealer, it's a wet cell battery and they sorted it out. You can see the voltage readout on the clocks drop when it's trying to turn over, it goes right down and the front light goes dim as soon as it turns over?
