A warning for all Bolt / SCR DIY oil changers - the oil filter easily gets stuck if overtightened then becomes impossible to remove without destructive force. Even the proper cap wrench skips and rounds the flutes and there's no room for a strap wrench in the narrow crankcase recess. My filter probably got way overtightened on the assembly line. The old rule was no more than hand tight (3/4 turn) after the pre-oiled gasket touches the base. Yes, I'm turning counterclockwise and no, I'm not going to punch a screwdriver through the canister. Need to trailer it down to the dealer tomorrow :[

Well, a search over at the Yamaha Star Bolt forum confirmed this is a fairly common problem on new motors. For example:
WTF? Oil filter is stuck!
I'll report back if the dealer has a good removal trick without cutting, drilling, welding or other risky last measures.

Don't know if it's too late or not, but see if you can find one of these steel wrenches at a local motorcycle shop.
It's sold by BigBikeParts and intended for a Honda Gold Wing. It also fits the Yamaha spin-on filters perfectly and won't slip or wear out.
I suggested one to my dealership's shop foreman and he now swears by it.
The photos show my former FZ-09 filter. Same size as the SCR's.
Newer wrenches have a 17mm built into the handle end for drain plugs.
I recall the original filter on my girlfriend's V-Star 950 being stuck.
We ended up smacking the end of this wrench with a plastic, shot-filled mallet to get the filter loose.

Most excellent suggestion, Eddie. Amazon has this tool as Show Chrome Accessories 4-201 Oil Filter Wrench at $12.95. I'm glad you included pictures confirming fit as the size is quoted at 2 1/2" = 63.5 mm. I would have assumed it might be too tight as the factory filter tool is 64.2 mm. This 4-201 tool looks much better than stamped metal cap wrenches that flex and are useless on tight filters. Meanwhile, too late for my present distorted filter, so next time.

Holy heck I didn't even know those existed. That should definitely make life a lot easier. I was gonna ask if there was anything else you could use for leverage just in case, but a mallet should suffice I think ?

Update from the dealer's service department: they discovered a factory assembly defect that caused a major burr on the thread of the oil filter mounting stud to the crankcase. Don't know how they removed the seized filter but it came out with the stud attached! Now the bike's waiting for the new part. Bummer

Holy cow!
Hope it was a 1-time deal and not something that affects many bikes.

It's sturdy enough one might could fashion a simple slip-on handle extension like the flattened pipe ones that come with some motorcycle tool kits.

That's usually my go-to in all scenarios. I have a select choice few of pipes for ratchets, powerbars, etc. lol. Can never go wrong with the good ol' solutions.

even better is being part of a community like this where you get to find out about stuff like this especially as winter rolls around and some riders go into hibernation.

Not too sure how I missed this update but holy heck the stud came out with the filter ?! I can only imagine how much of a headache you would've had attempting to take it off :|

How long was the turn around time to get the bike back ??

The damaged stud is #3 and should be torqued to 51 ft.lbs. No wonder the filter can distorted trying to back it out after the threads seized. The stud had to be ordered from Yamaha USA and turnaround time at the dealer was three days. I've changed the filter since with the aid of the magic Big Bike Parts wrench Eddie pictured above - it's perfect for the job.
