Never had that problem on a 2 stroke oops don't want to offend the 4 stroke boys.
Just drill the head off. If it's a 6mm bolt (5mm hex usually) then drill it with a 6mm drill till the head of the bolt comes loose. Don't go any further. The hex hole will centralize the drill for ya. Pull the cover off and you'll be able to grab the protruding bolt shaft with some vice grips and get it out. Unless it's been cross threaded it'll be loose once the tension is gone.

Sometimes you can grind the head of the bolt down to the cover so theres no more head left, remove other bolts and slide the housing off. This will let you get at the bolt properly and heat and CRC it, and leave it overnight. It'll come out then. Yes, you will need a new bolt, but you need a new one anyway.![]()

quick update tried drilling the bolt head off. Took ages and blunted my drill bits. Got an old bolt that i dont need and tack welded it to the offending bolt head then got socket and ratchet and of it came after the torque was cracked it. Now heres the penny thats dropping the reason the dumb prick who perviously owned the bike prior to me did the bolts up so tight was becuase the dickhead installed the oil filter back to front . I only have had 5hrs use out of the bike how much damage do you think has been done becuase of incorrect oil filter installation
cheers
To be honest you'll have to get into the head and check for wear and tear on the cams and valve stems, plan on the worst case of a fucked head and piston\rings and then find the previous owner and try and get some money outta him or at least kick him in the nuts.
The cost to replace the cylinder head can be more then the bikes worth if you get the parts new from Yamaha NZ, best try EBay for 2nd hand in the states.
wil probaly trade up if thats the case!!
Any decent machine shop, welder will fix this for you for low cost. I recall, even on the old Yam TT600's you never over-tighten the 3 Allen keys on the oil filter cover - seems like nothings changed, typical Yamaha trait
Best case is that the oil went through without being filtered - in 5 hours use (if the oil was fresh and uncontaminated) shouldn't be any damage at all.
Worst case - no oil could pass through - the engine is probably history. After 5 hours you would have heard it / felt the vibrations and most likely the engine would have locked up
it's not a bad thing till you throw a KLR into the mix.
those cheap ass bitches can do anything with ductape.

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!!!!
my yzf450 08 had a rattle at idle that went with a few revs it more just the way they are mate did a whole lot a looking into it on his wr and it was put down to the carb slide rattling at low revs reverbs through the whole motor (im only repeating what was told and he found out after a lot of looking and question asking)
al lot of it will also be the auto decomp once worn (spring ) will lose tension it rattles put in gear hold brakes and load up clutch with revs if noise disapears that will be what it is = dont over stress
