Others on here have more experience than me with these engine's but here's my thoughts on this
Was the primary chain jammed when you removed the cover it could have jumped then jammed removing the cover could have freed it off any swarf in chaincase? would point to a loose primary chain if all good in primary my next look would be the oil pump worm these have been known to strip after just one kickback any whear on the splines replace the worm and drive with a british one from our host fragments from the worm should get caught in the timing case and hopefully not get to the crank
Hopefully you will have found the problem by now but if not take off the pushrod adjuster cover check clearances if still all good Off with it's head and barrel piston failure is not unheard of as has been mentioned earlier
To be perfectly honest if I was running a Indian built engine I would upgrade piston and oil pump as matter of course just for piece of mind
Hope that makes sense Dai
