oil over the place
Discussion
Up at knockhill today, I suspected a little oil leak from the 675 before, but after cleaning it up it looked to be fine, so a new oil and filter on Friday and off to track. I thought it was just from me spilling some when filling it that had got under the casings, it never leaked on the road.
I felt the rear almost go a few times, just all of a sudden but kept it up right, thinking "must have f
ked that corner up". Weird as hell feeling, no warning.
Get off for the final session, my boot is soaking, so is my right hand side of the bike.
Get it home and find this
I lost half a litre of oil, very lucky.
Is it possible with the damage to the casing that it has cause a hairline crack/pin hole and the oil is pissing out on the track under pressure. Its hard to tell where its coming from but I suspect its that casing.

Its oossible, yea. Its also possible the cover is warped so that oil is leaking past the seam (if you get me). Degrease the whole area and clean it up, then run the engine and throw lots of talc over it - you should be able to see where the oil is seeping from.
Are there any breathe pipes there that might have ruptured?

Not that im aware of but don't hold me to it.Are there any breathe pipes there that might have ruptured?
I heard about talc, what will it show, just it soaking any oil?
The first picture is of an crash protection cover that was fitted over the casing , yes?
You need to take that casing off and inspect it and the crankcase around it for any damage/cracks, if it and the engine casing around appears to be fine, re-fit it with a new ( genuine IMHO) gasket( you never know, it may be that it should have a gasket and its not been fitted...) and away you go.
I had a similar leak with a GSXR600 in the past, that did need a new engine case cover , most recently my LC leaked oil from an engine case when first rebuilt, due to the fact the faces of the cases where not pefectly smooth, a new gasket and a thin smear of Loctite gasket sealer cured that one.

I reckon the casing has just loosened the gasket after the knock that it's had, so that'd be my first thought to replace, although I'd do the casing too, as I like to play it safe.
There's a,so the chance that you haven't tightened the new filter enough. I've done that once. Never again.
Bear in mind I am a mechanical a muppet though.

filter was tightened with a torque wrench, its obviously been weeping for a while as I had a small amount at my casing the last time. There's a,so the chance that you haven't tightened the new filter enough. I've done that once. Never again.

Maybe the pictures don't show it very well but they don't look lagged in oil at all. The inside of bellypans always look like that after a while, they just collect road grime.
Its just the pictures, its very hard to show up. My boot was covered in it, the casings soaked, your never going to see it particularly well on a photo.
I took a fairing bolt off and it looked like it had been copper slipped it was that bad.

ITS f
kED, new one ordered £80 odd including gasket. It came apparent that when up to temperature and on revs that it was dripping quite badly, obscured by the casing protector. The off at Croft must have finished it off.
On a positive note, I drained the oil and it is spotless, not a lick of dirt came out. Mind you it gets changed every two trackdays

Then it's not doing its job! Or you're a pussy with the throttle 
its turned black from red, but I meant no big fk off bits of metal. To be fair it has only done one track day.The other basin I use for regular oil changes sits in the garage, its full of dirt, grit, sand and dead spiders.
I know your meant to check your oil to see for swarf, but when your basin is full of s
t its kinda difficult and I cant be arsed cleaning it.Edited by moanthebairns on Tuesday 2nd September 14:55
