...These bolts only need enough torque to compress the o-ring - two fingers 4 inches from the pivot is a gracious plenty. If your bolts "never even get remotely tight", then there are three helicoils in your future...
The CBR250R uses a metal compression gasket for the oil filter cover, not an o-ring. Four cover bolts, not three. You doing you're own oil & filter changes Luke?

Oops - changed the oil last weekend on two Honda four-wheelers, which have three bolts and an o-ring. yes, I do change my own oil, but not in the last couple of months on the CBR. I stand corrected and pay homage to your superior memory.
However, everything I said is still applicable, except now you need FOUR helicoils....
DO NOT use torque wrench like the manual says or you will strip the bolts,
12Nm is about a billion times too much and torque wrenches generally dont go down that low.
Its one thing that is wrong in the Owners Maunal, and has caused some grief for a few ppl.
Ive written a guide here that mentions it-
If you have stripped the threads you will need to Helicoil them.
This is a great guide you've put together. I'm due for my first oil change next month and after reading the reviews for all my local dealers and shops I'm scared to death of letting them even touch my bike. Granted, most people will write a bad review before a good one.
I'll probably take it in this time but if all they are going to do for the 600 mile service is an oil change I'm still capable of doing that myself.
by the way, one of the 4-wheelers has a Helicoil on one bolt, which was how I learned that my fingers were better than a torque wrench for small bolts.
What size/type tool did you use on these little 5mm aluminium threads ?
Ive changed the filter 4 or 6 times and the oil at least 12 times so far in 8000km (because I do track days)
every thread on my bike gets a smear of Silver Anti-seize the first time I re install anything.

Yeah, unless you are going to have the dealer do the Valve Clearance Inspection, you can save some money and do the oil & filter change and the other 600 mile service/maintenance items yourself. It's not rocket science. IMO, the VCI can be put off for a while... mine were at factory spec when I checked them at 1200 miles, and still in spec now at 5500 miles. Then again, maybe I just got lucky and got a good one from the factory.
Working on your own motorcycle is not always cheaper,

I think it is cheaper in the long run - but you will have some painful lessons along the way. The amount of pain varies with the ambitiousness of the project. Putting in (or having some else put in) a helicoil is a relatively small "tuition" for the education you receive. The tuiton for, say, getting the cam timing off can be much more daunting - something like Harvard versus your local public university.
I don't know if the tool question was aimed with me, but for bolts that size I use a 1/4" ratchet with a short handle. Your ratchet knob on the drive handle is just as good.
