Starting problem

[Lank]

Put the jump leads back on and fire it up again. remove jump leads and while the bike is running check the voltage across the battery. At tick over it should read approx 13.5v and if you rev it to approx 3500rpm it should rise to about 14v. If you get these readings then the reg/rect is working correctly and you have a duff battery

Thanks Nickodemon, I remember reading that before now. Ill jump start it again later and then measure it
