Valve clearance (cold)

Intake valve
0.10–0.14 mm (0.0039–0.0055 in)

Exhaust valve
0.16–0.20 mm (0.0063–0.0079 in)

Tq for your reply,

Currently im using 62mm racing block, cms T2 cam and cms spring valve.
I can start the engine normally but if i twist the throttle lightly sometimes the engine dies. May i know why is that. Btw my ecu is tuneboss.

I'm not familiar with injection and ecu tuning.
You can check your plug color to confirm it. Then adjust the ecu, if it show rich make the rich lower (lean it) for lower rpm/starting.
In carburetor system, this shown a rich setting in lower rpm/starting. You can adjust it to smaller pilot jet or adjust the needle level.
