My black dc2r

[Super-DA9]

Not quiet the same engine but my B16A would have a noticable kick when vtec engaged.
But after i did a valve clearence adjustment, the kick wasn't quiet as noticable but overall felt like it was more smoother and had more top end power.

Turned out that a couple of my exhaust valves where way too closed.

You sure? Valve clearance adjustment won't make any noticeable change in performance unless you make the clearance too tight. In which case the valve does not fully close, causing loss of performance.

Ya that what the problem was, the 2 out of the four exhaust valve had no gap between it and the cam.
Feeler gauge couldnt get though at all.
