Thanks for your replies and the kind xt660 welcome, I forgot to say that on Friday I rode it home in the rain so you could be right with wet ht leads ? The reason I think you may be right is that I left it in the garage all weekend and tried starting it on Sunday afternoon and it started first time - Had it dried out ? but also have to agree with plug possibility, as its not firing, turning over but no ignition, I will try a new plug and come back to you with the results, could it be running too rich with the fuel mod ??

Thanks guys - helped me a lot - just understanding what's going on .....
Cheers
Dean
