For the Lifan KPX, the manual gives clearances of .08mm intake and .10mm exhaust. So yours might still be too tight.

I specifically left that out because at one time I did include it. It's not included so I simply don't have to deal with 50 experts all telling me the numbers I included are wrong and theirs were right.
.05mm is fine. >.05 to .08mm is perfectly within range of every CG engine ever made. Zongshen states theirs as .07mm for both valves with a 2500 miles valve check interval.
The .04mm may be a bit tight, but I have also seen Lifan Xpect lash figures states as .03-.06mm as a range for the intake.
I personally stick with no less than .05mm intake and .07mm exhaust.
