Had bought unicorn bike on dec 2015. Had been doing proper care and maintenance of my bike since the beginning. Two months back was facing m\engine missing, took the bike to showroom, was told there is complain in the engine head. Repaired it. But after the repair my bike doesnt have the same power as earlier, my friends unicorn too faces the same problem. Its a manufacturing defect. Just want to know if there is a way to repair my bike to its initial condition. Unicorn may be a great bike. But if this particular problem happens to your bike. U can kiss the comfort good bye. Can anyone hep me get my bike fixed
