hi people, i need some help on doing valve clearences, i have the right tools but not sure how to do it, any help please??
 
as long as you know the clearances of inlet and exhaust plus know which is which eg; inlet / exhaust, all you need to do is very slowly turn the engine over whilst watching the valve tappet go up and down, you need to find the off rocking point of this valve where there is stationary movement, meaning the valve / tappet is in a no mode move = freeplay. this is when you can adjust this particular valve to the required setting.
 
i need to adjust myn as it is making a strange noise and i was advised they need to be adjusted.
 
when i rev it makes like a fuzzy vibrating noise, its sorta hard to explain but yer
 
thanx for the help but for some reason that video isnt working on my computer
 
oh and would anyone know what the clearances should be for a dhz 138 (actually a 127).
