So I was given this motor 2004-05 with the words burns oil , and yes it does .
Looks like someone mistook it for a choice cut and tried to BBQ it, LOL...
The only way that thing is going to burn oil is if you overfill the crankcase, stuff a rag into one of the ports...and light it up, like Molotov cocktail. With a top end that completely fragged, you'd have to rebuild the motor & wear it out first, before it could burn oil in the traditional sense.
BTW, that IS rebuildable
That looks terrible.lol.
Looks like it swallowed something down the intake and hammered on it awhile.
Top ring was broken . BBR kit stock head .
The bore-up kit is a logical choice. I'd retain the stock cylinder, it should have enough material to overbore (someday)...cast iron can withstand a lot abuse. You should be able to carefully sand & polish the scarring out of the combustion chamber, with very little impact on total volume, especially with a 52mm piston.
One thing that I'd check, closely, is the crankshaft assembly. The rod or/and crankshaft may have been bent. I'd also be looking for excessive clearance (radial & sideplay) at the big end of the rod.
Thanks piece of the skirt by piston pin was also broken
