Afternoon all

I've just swapped out the left engine cover of my GSX650F. It is very slightly leaking oil when the engine runs, we're talking one drop every 2 minutes. Still, it'll fail the MOT.

So, having just changed the oil as well; what's the easiest method to tip the bike to its right side, (away from kickstand) and save the new oil from being drained when i take the case off again to switch out for a new gasket

Also, can anyone confirm the torque for the bolts, I've a haynes manual and can't find the spec anywhere.

Hello,

Yes, you may lean the motorcycle so you won't lose the oil and torque figures are not that important here.

Make sure you clean the mating surfaces properly. Use proper paper gasket, you may fabricate your own.

Yep sounds good

I guess i can just drain the new oil and re-use it

All the same, what would the torque specs be

I've ordered a new gasket Wink

Yes, ignore torque values and strip thread etc., particularly if you have 4 Weetabix for brekers or don't know your own strength.

6mm thread recon on 6 lbs ft, , 6 to 7 lbs ft range at any rate.

just take your time and don't get any silicon or any sealer down the threaded holes, as they may/can/do burst.

Ever made your own paper gasket ? A good skill to have.

Perfect! Thanks for the specs on torque, i'll convert to NM's
I've not made a gasket before and frankly don't trust myself given that they're only £10 from Fowler's.

I'll be putting locktight on the bolts as per norm for any bike related stuff, couple months back i didn't when cleaning the brake calipers and one came loose mid ride!

Final point to clarify, and bear with if it's a ridiculous question; the new oil i've put in that's had less than 10 minutes of run time to circulate, that'll be fine to drain and place back in once this job is complete right? There's not some un-written rule to never recycle brand-new oil is there?

Confused

Why would anyone use silicone? Sealants are the cancer of every single garage! The easy way for those too lazy to do the work properly.

Yes, simple stuff, doesn't have to be perfect.
EDIT: Doesn't have to be perfect in this case. If, for instance, you make a gasket for between the two halves of the crank case, then you have to make sure you have the right thickness of the paper.

Some manufacturers specify sealant at certain points, the VFR for example specifies sealant at two points on the alternator cover.

Yes, if it's specified by the manufacturer, then it is alright.

But the horrors/stupidity I've seen over the years is just ridiculous. I bought a motorcycle from a lad who glued the carburetor bowl to the carburetor because he torn the seal. He used the multipurpose red silicone, which shall not be exposed to the petrol nor heat, and as it deteriorated it first clogged up the jets and then the bowl started to leak. Of course it didn't leak when I was buying it.
My fix was a proper seal, made by a specialist and I paid maybe £2 for it, not sure right now, and guess what, it worked. Shocked

Then I bought a motorcycle where the previous owner glued the exhaust silencer to the rest of the exhaust system with the very same red sealant. I also have seen someone using the exact same red sealant instead of the head gasket, completely messing up all the coolant and oil ways into the head. And I could go on with such horror stories all day long... Neutral
