Munted bolt head on oil filter cover

[green machine]

well its still runs and pulls like a tractor. has a bit of a rattle at idle though! from there upwards it seems fine!
I bought the bike at a dealer. went there today told them the situ, turns out they rebuilt and serviced the bike before they sold it to me. they tolde me to bring it in they will check it over and repair and damage that this has caused or worst case scenario rebuild the engine for free. so i'm happy with that! They are a bunch of good cunts at colin clyne motorcycles in oamaru highly recommend them if any of you live in north otago!!!!

I'm new to Yamaha's mate,always had Kawasakis before then.......the first thing i noticed is the noise they make(450's),they sound like tractors compared to the Kawis.....i was so paranoid at first but i'm used to it now,any Yz450 i've heard sounds the same......i did heaps of reading on here which put my mind at ease

As the title says i went to change the oil and filter on my YZ (first time its been done since its previous owner) and the 1 of the 3 allan headed bolts is completly stripped round and over tightened beyond buggery. Lots of foul language was used when i found this and the urge to hunt down previous owner and kick them in the head Haha. so Boys and girls, what should i do? what would you do?
cheers

Same thing happened to me on my ktm. i tried every thing with no luck! so i got engineering on it!

Rounded sump bolt, i drilled a small hole through the head of the bolt then pushed a hard metal pin through so the spanner jammed against it, the it came undone!

Oil strainer bolt, there was nothing else left to do bot to weld a imact driver to it!!!!!!!
