HI all, i have this engine oil leaking problem. I wake up to a small pool of oil every morning after i did oil change. I lay on the floor and try to see where the oil is leaking from but could not see any place that has signs of oil leak.Its getting on my nerves. and on some days i will find another two spots of small oils that is located near the the end of drive shafts. Any one could advise ? Thanks in advance

If you changed your oil filter as well then its likely the o-ring seal on the cover is damage or not seated properly. The 3 screws securing the cover need to be tightened evenly.

Oil Filter Cover o-ring
88mm x 3mm

What oil are you using?

My favorite trick for finding an oil leak on black engine parts:

First clean the bottom of the engine (and any oil-wet area).

Next, get some white talcum-powder spray at the drug store. The kind for curing athlete's foot is perfect.

Spray all the case seams around the bottom of the engine so they're white.

Take the bike for a ride. Oil leaks appear clearly as black against the white. When you've found the leak, the white stuff will wash right off.

Good luck!

Great tip! I have used talcum powder for years going back to when I built industrial hydraulic systems, but never thought of the spray.

Brilliant!!!

One caution, though. Any oil still trapped in the joint between two parts will be sucked out by the powder, and may give a false indication of where the leak is coming from. There have been times when it would take several applications of the powder and then washing it away before enough of the stray oil was removed to give me a good reading.

A good rinsing with a strong solution(50/50) of Dawn dish detergent in water before powdering will go a long way toward eliminating false indications, especially when trying to find very minor leaks.

That's a great idea to use the spray talc but if there is enough oil to pool on the floor overnight it really should be visible on the engine casing so maybe it's not coming from there.

Is the oil pooling on the left side of the bike?
You may have overfilled it and especially if you leave it on the side stand then it can leak out the exhaust ports into the headers. It can also make its way down to the back of the bike via the exhaust system.
Other symptoms will be a very smelly exhaust, especially on startup and a very thick sooty deposit on the tailpipe.

They're easy to overfill if the sight glass has gone cloudy and its not unheard of to have oil leaking out the exhaust system if the sump is over full.
Just drain the warmed oil overnight, measure 3.5litres and replace. Make sure it's on the centre stand.

3.75 litres without oil filter sounds too much to me.

Optimum level is the centre of the red dot in the middle of the eye glass on the right hand side of the sump. Bike must be on main or centre stand for this. Ifthe stand is broken sit on bike and get someone to keep an eye on it.

Kaptain Holister's advice is best,drain it off again into a clean container,refill slowly butwhen you refill keep an eye on the sight glass.

I reckon even 3.5 is a little too much and if you don't drain it completely you'll end up too full.

3.75 lit with a filter change
