CBF 125 oil filter cleaning

[Screw Loose]

So after putting it off for almost a year I've bit the bullet and decided I need to clean the oil filter, so I've ordered all the bits and bobs and am going to sort it on thursday. Now, having looked through the Haynes manual, they reckon the clutch cover should be tightened to 10NM,
Surely this can't be correct, given that the spark plug is supposed to be 25NM?

Also, seeing as though I've got the clutch cover off anyway, is it worthwhile cleaning the centrifugal filter also? I'm just a bit cautious about working on my bike as I don't trust myself and lack confidence, however if I don't start soon I never will haha.

Cheers in advanced

Apparently you have to be over 21 to buy it from B&Q ...

errrrr, the centrifugal filter is the only filter on the cbf (unless you count the tea strainer)

its the reason I change the oil every 1k. it's only a litre and if you buy Halfords oil on offer that's £2.50 every 1000 miles at 5k I took the cover off and washed the strainer under the oil pump pickup, which was fair full of crap (mostly clutch fibres). I will not do the centrifugal filter ever because I cleaned the one in my cub 90 at 25k, and it had only the merest little bit of sludge in it. keeping the oil clean / fresh makes much more difference.

edit: I never have used a torque wrench, especially on spark plugs. if its a new plug with a crush washer, its hand tight + a quarter turn. used plugs / crush washers are 1/8th turn, and tapered washer-less plugs are also 1/8th turn.

Torques given sound ok to me. Spark plug has all the joys of compression happening which a cover doesn't. Overtighten your cover screws and you'll end up cussing and playing with a helicoil set (or worse)

Just hold the ratchet as close to the bolt as possible and nip it up, you really should be able to feel if your are about to strip it.

So just nipping it up?

For some reason I was expecting them to be really tight


Thanks for letting me know before i start anything though

A nip should do it. The torques are similarly low on my CG as well. I figure if you do it up and there's a bit of oil seepage, it's easier to tighten them up a touch more than deal with a sheared bolt.

If you don't know the history of the bike, there's no harm in cleaning the centrifugal filter. If nothing else, it'll give you an insight as to how often the oil has been changed on it.

The spark plug is torqued to 16Nm on the CBF. With the cover screws at 10Nm they won't rattle loose. The strainer gets blocked with fluffy crap which I assume comes from the clutch, so you should clean it as a matter of priority. Subsequently it will be much better the next time you do it.

As for the centrifugal filter, the ones I've seen only catch a thumbnail's amount of gunk, not much at all. I broke an impact driver trying to get the bastard thing apart and never cleaned it since, 31'000 miles since. I don't think it's nearly as important as the first clean out of the strainer.

Have a look at my guide for the strainer if you like: https://cbf125rider.wordpress.com/2011/12/11/how-to-clean-the-engine-oil-filter-strainer/
