Hey aitken
that's exactly what happens to me! My engine runs quiet till it heats up a bit, then the tappets get loud And I'm running castrol 4t.
Annoying!!!!
And yes I've done the valves.

most the time its not actual tappet noise your hearing, its the rockers slapping around side to side...

the type of oil shouldnt make it any different..

klx style china engines are know for this..

if you wanted to make sure its not tappet clearance then set them when the engine is hot.. .002 tho on inlet and .003 on exhaust..

hey sean
if its the rockers slapping from side to side shouldn't the noise be there when the engine is cold also ??????

im at a loss to explain why theres no noise when it starts cold and about 5 min later the tapping noise is back ????
