cheers peace of mind is important, old reciepts show regular oil changes, perhaps it is just carb balance, tookit out before and roughness is around 3500 - 4500 revs at 6000 it starts to smooth out a bit, maybe i'm just not used to the bike and it needs a balance, will balance carbs tomorrow and see if it fixed it. (ps) inspected all jets today. 1 pilot jet seat was bunged and the mixture screws were wrong.......it ticks over so steady now, but rear axal nut is seized ho hum
