Let's say that hypothetically, someone was to put the oil filter bolt in at an angle without realizing it... Then lets assume that same person thought it was a tight fit and then continued to wrench on it until the internal threads became junk and cannot be replaced or fixed with a tap.
It should be pointed out that the bolt threads are still in great shape and it was the aluminum it was being screwed into that caused the damage.
As this part is beyond repair... It looks like the bolt should go into the cylinder block but it also looks like that part of the engine might actually be able to come off without needing to replace the whole block.
Am I correct in assuming that it is the cylinder block and that where the oil filter bolt goes, can be removed as a separate piece?

What you need is a transmission cover 11360-MG9-950.
There is one on ebay at the moment for $100

Depending oh how centered your hole is in that boss, this could be Heli coiled. But I would say that isn't a DIY job for you. Considering getting it perfectly square is required.

Re: Oil Filter Bolt Placement On The Engine
I'll look into it. This happened out of a lack of wanting to lay down on the garage floor. Hind sight is always 20/20. I've had the bike for 10 years and changed the oil a minimum of once a year with no issues except being 10 years older and not owning a motorcycle lift like I should.
Can the part that the bolt goes into be replaced? It looks like it is only held on by a few small bolts.

Re: Oil Filter Bolt Placement On The Engine
Since this is hypothetical I will assume someone snuck into your garage with an uncontrollable urge to change the oil on a motorcycle. The answer to your hypothetical question is yes it can be repaired. Just make sure you lock your garage doors so said person can't get near your bike a second time.

DingDong, Darn people sneaking into my garage. LOL
Sorry Rambozo, I completely missed the first paragraph.
I think with the damage I did, it is just going to be easier to replace the transmission cover. That said, I can do both. I can work on the old one while it is on my work bench and still be able to ride.
Thank you.

Re: Oil Filter Bolt Placement On The Engine
The reason I always thread the bolts in all the way by hand, and then snug down with a tool.
You could helicoil it, but I have had less than great results with helicoiled oil drains. I had a 1991 MR2 Turbo once upon a time, was laying on the driveway changing the oil, and when I removed the bolt, the helicoil came with it. Previous owner had put it in there, I guess. I now had a car with no oil in it, no way of putting a bolt in to seal it, and no car to go drive and get parts.
I prefer Timeserts, if they are available in this size. They lock in place and can't back out.
