cheers for all the info,im using motul 5100 10w40 and ive used it in all me other bikes but seems to make the engine a bit tappy,but that could just be my ears as i did spend 23 years as a car tech and you hear things you really dont want to,and yes you can buy amsoil over here from opie oils in cornwall but it works out to be about £70 for 4litres a wee bit to exspencive for me.cheers again
