where is this screen located Jack?

On Evo motors between the rear tappet block and oil pump, you will see a slotted screw or a domed nut, its under there with an o ring seal:s

have not checked the oil pressure or cleaned the tappet screen. Not really sure where to start with this issue since the noise is coming from the cylinder head area. How would I check if the lifters are pumping up at start up?

Are you using 20/50 oil?

Checking Oil Pressure by removing the IDIOT light sensor and install a Manual Gauge to see the pressure at Idle 1200 RPM "cold" should show around 25 lbs at start up and 40 lbs at 2000 RPM " when Cold... after warmed, the oil at 1200RPM should be Not less than 10/12 lbs OR close to that.. and Run at 35/40 at riding speeds.

Idle of that carbed motor MAY be too low, causing the oil pressure to be TOO LOW when it idles,, ie: causing "low oil" to the lifters,Lifters making the noise you hear, until speed up motor PUMPS enough oil to silence them... If NOISE goes away at 1100/1200 RPM,,, all is probably normal and not to worry.... Don't try to IDLE engine Lower than the 1200 RPM level.. The motor Will Not pump enough oil thru-out the system at a Potato-potato idle!!!!!

Any auto parts store should have an accesory gauge kit:s

ok checked my oil pressure last night and it's idling PSI is 12 and about 32 at 2000 rpm. This morning when it was cold the pressures were where Jack said they should be in a earlier post. Still clacking until she warms up......any ideas where to go next?
