Tried my first oil change

[onlyJaz]

All was going well;

I drained the oil, fully black oil. I opened the side casing to clean the oil strainer. Refit the casing and put a touch of oil in and noticed there was a slight leak coming from the casing. It has a gasket between the metal casing which is where the oil is leaking through..

Please any advice? I have a YBR 125

Did you replace the gasket? Did you tighten the bolts on the cover to the correct torque?

If it's leaking, yes I'd replace it. I'd also be sure that the old gasket was completely removed before putting the replacement one on.

Is it a thickish round-section rubber gasket, or a thin, flat one that's a bit fibrous?

Round-section are usually re-usable. If it's a flat one, they don't tend to squish back down as evenly.

For the sake of a few £££ you might as well replace it.

Pikey options are:

Make your own from a cereal packet. Yes, totes srs.

Seal the existing one with blue hylomar / RTV gasket sealant. Clean off the gasket and the faces thoroughly, and use a very thin smear towards the outside of the gasket. Having it squidge out of the casing is fine, you don't want any being squidged inside and getting in the oilways.

It really isn't. You can't see where the excess instant gasket is going, and all it takes is for a small bit to break off inside your engine and get stuck in an oilway and you've got a dead engine. You are better off making a gasket from gasket paper or even an old corn flake packet. Instant gasket is the work of evil.

The proper gasket will be better and cost less than instant shite.

I think the noob comment is key there.

An idiot using the correct tool incorrectly can still break something. In the same way that an experienced person can use the wrong tool and still get the job done safely. (caveat: this in no way should be taken as an admittance that instant gasket is the "wrong" tool... Its an analogy)

and I disagree Chris-red (on your costings at least). I'm still using the instant gasket I paid £12 for a good few years ago. I use about 5ml or less for a gasket. so it costs me roughly 22p for a gasket that (imo) works perfectly well.

An update guys..

So I ordered a torque wrench and a new gasket, they both arrived during the week and I realised the wrench was WAY too bulky for the small bolts of my clutch case

So I fit the new gasket and used my own judgement to equally tighten the bolts very slowly one at a time in a crosscross pattern to keep it equal, it hasn't seemed to leak anything yet so hopefully it is all good.

Changed the air filter, changed spark plug, tightened the chain (it really is so easy), decided to give the bike a bit of a wash down, cleaned the chain, sprockets & front disk, lubed the chain and pretty much completed my first service so I'm quite chuffed.

Two issues to note;

1) When I started it after the spark plug & air filter change, it was choking a little and it was struggling to respond to the throttle for about 2 seconds on each roll of the handlebar. But this problem hadn't come back after a few times so I stopped worrying about it.

2) sometimes I heard a loud click when I press the rear brake whilst riding, I'm not sure if I have tightened it properly after adjusting the chain. It stops the bike fine, no error there but not sure what the click is but I'm sure on close inspection I will find out

Thanks

I did slacken them both and tightened the torque arm after adjusting the chain.

The brake adjuster was weird, I was trying to tighten it back up but thought I might have been overdoing it (not sure if it was meant to get tight or what the ideal position is supposed to be) so I did it a bit and left it at what I thought may be okay

I back the adjustor right off while I'm moving the axle, then check the brake actuator arm is free to wiggle (drum brake mechanisms to tend to gum up). Then when I've locked the axle off, I do the brake adjuster up until there's just a little bit of slack left in the arm.

Your click, could it be a spring fouling and releasing?
