Where to adjust the valves on 83 Yamaha tt 600 r?

there are two round silver (on my tts) caps on the front of the rocker cover with 17mm heads like a bolt these are for the exhaust valve tappet adjustment 0.012-0.017mm (0.0047-0.0067in.)clearanceon the back of the rocker cover there is an oval shaped plate with 2 Allen head bolts holding it inside here u will find the inlet valves tappet adjustment

0.05-0.10mm(0.002-0.004in.) clearance with cold motor at T D C but i would strongly suggest u get a workshop manual to do this job to help in aligning timing marks finding top dead etc...
