Blue smoke, in VTEC, is almost always oil burning. Check your oil levels.

Also vtec on the Z6 is minimum 4800 RPM. I don't have vtec but that's about the range I start smoking and I have solid 200 compression on all 4 cylinders. So more than likely oil control rings for me. Smoke only at high RPM usually WOT even though I can get it at 3/4 throttle just not as severely.

You could have a similar issue. If you get good compression numbers and don't smoke on take off until 4800+ rpm or smoke on deceleration, then you can pretty much rule out valve seals typically and the usual diagnosis is weak/bad oil control rings.

Your mileage may vary.
