Two late penalty-corner goals from Bournville could not prevent Khalsa securing their fifth win on the bounce.
Jas Singh and Dave Harris both returned to the Khalsa squad and were instrumental in the victory.
Gurminder Ghattaura brought out two saves in quick succession from the visiting keeper before dragging a shot wide of the post, while Alex Idoine was unlucky not to find the net with a well-worked corner routine.
A reshuffle in personnel and formation allowed Khalsa to be more attacking after the interval and Harris, Idoine and Ghattaura combined for the latter to convert a simple tap-in.
Khalsa were dominating possession and good link-up play between Jack Wells, Joe Colantonio and Sean Robinson led to a goal from Harris who stopped a pass across the face of goal and chipped the visiting keeper.
With Bournville pressing higher up the pitch in an effort to pull a goal back they left themselves exposed at the back and an aerial ball from Jas Singh found Idoine one-on-one with the keeper. Khalsa’s leading scorer producing a bullet reverse-stick strike to open up a three-goal lead.
Bournville reduced the arrears in the final five minutes with penalty-corner strikes from James Claughton and Tom Rowland but the home side held on.

Leicester responded with a well-worked breakaway goal to level.
However, Khalsa were not fazed by the setback and worked hard to earn several short corners and it was one of these that proved the match-winner, Harminder Hundal scoring with a strike across the keeper after a well-executed routine.
