Kapur's overall total stood at five-under 139 after the halfway stage of the European Tour event.
For the second successive day, Kapur found a birdie on the second hole but was pulled back by a dropped stroke on the third.
But back-to-back birdies on the sixth and seventh holes helped him make turn two-under. The Indian's back-nine was a subdued affair and he parred the first six holes before stumbling to a bogey on the 16th.
At the top, Spaniard Pablo Martin carded a brilliant 63 to take a massive four-stroke lead with an overall total of 13-under.
Local favourite Ernie Els (67) and Italian Edoardo Molinari (69) share the second spot at nine-under. PTI PM
