I have a horrible feeling I have an oil leak

Post by mick shere » Tue Mar 12, 2019 11:05 am

I've been in denial for a while but occasionally I find a small patch of oil under the engine under the front sprocket area, I keep thinking it is from the scottoiler (an automatic chain oiler) its very thin and doesnt smell of anything really.
The strange thing is it only happens occasionally usually after sitting on it then putting it back on the sidestand.
I found a small patch on a newspaper i put under it last night even though it hasnt been started for 2 weeks.
Does this sound familiar to anyone?

Sounds like Scotty isn't house trained yet.

Based on where you see the oil; your leak should be caused by one of three or four things:
A. Leaking gear shift seal (this happened to my 1290 R and it is an easy-ish and cheap fix)
B. Leaking counter-shaft oil seal (have not seen this happen yet, but this leak also shouldn't be difficult or expensive to repair, but you might have to "break"/remove your chain to remove the counter-shaft sprocket and gain access to the seal)
C. This could also just be excess chain lube that has collected and dripped out of the counter-shaft sprocket cover. You should be able to determine if that is the source by the color and consistency of the lubricant you are seeing on your floor/cardboard
D. Possibly a hydraulic leak from your clutch slave cylinder. They do go out on a regular basis. Replace it with an Oberon slave. Not cheap, but a vastly superior unit that can actually be successfully rebuilt. Again, you should be able to determine whether it's mineral oil or DOT 5.1 by the color and consistency of the lubricant you are seeing on your floor/cardboard.
Hopefully this is helpful information.

I concur with mikesoldebikes...... you are just going to have to get your fingers dirty to find the real source :lol: before doing anything serious like splitting the chain..... surely the sprox will come off after loosening the adjuster cam?

Hopefully it's just chain oil (maybe the fuel overflow hose has dripped some gas onto the sprocket cover and dissolved some chain crud......or, I suspect (as the rumbling of a severe thunder storm gets louder and nearer to me here in :lol: sunny :lol: bloody Queensland Aus :roll:), that it may be your chain oiler has a vacuum leak, or has vibrated to a faster drip setting. (thinking if you have one of the motion activation oilers vs a vacuum or electronic type.... sitting on bike then back onto side stand might activate the drip feeder... :?: ).

No drips under my SDGT (bare concrete floor) in 2 years....... only drip on my floor is when I lie down to get at the oil filter on my CBR1100XX...... :lol:
