Spitting oil after a service

Whoever thought sight glasses were a good idea needs to be burned at the stake.

Was the oil change with a filter and is the 1.5l just oil change or filter and oil change

Oil and filter

Whatever you do, do not over fill it! it's easier to fill than to take away.

Your bike takes about 1.2 litres after an oil change and 1.5 total - you can't drain all of the oil. You should be putting back an absolute maximum of 1.5 litres (unless of course you've always had an oil leak that you didn't know about previously...)

Next time you see the black liquid from the exhaust, rub it between your fingers and see if it's oily. If it's just a mix of carbon and water then it won't be oily.

Also re-tighten your filter and sump plug. The filter should be hand tight and the plug torqued up to specification (15nm)

The correct way to check oil is to warm the bike up to working temperature. Switch it off. Wait 1 minute. Check oil level.

Judging from the issues you've been having I would drain it again and start fresh.

My manual states 1.5L, there's only the odd site that state 1.2L which I don't think is right. I also thought you checked the level when cold like on a car, maybe this is where I went wrong?

Small amounts of water in an exhaust usually means there is a running engine connected to it, particularly in winter when the water vapor condenses more easily.

Ignore the water drain in the exhaust at this point, small amounts of black water coming out in cold weather is absolutely normal.


It should normally smell of soot

0.5L extra in an engine with a total capacity of 1.5L is more of a worry, an empty filter on a small bike engine won't take 0.5Litres to fill. However if the oil is showing at the correct level in the sight glass (or dipstick) with the bike completely upright (not on the side stand) then everything should be fine.

I put a little more oil in it today, did a 5 mile round trip and left it for 5 minutes. Now when stood upright the level is in the middle of the window but I know I've used over 1.5L as there's not a lot left in the can (why did I buy a metal tub lol), I'll have to measure what's left in it for peace of mind. I did leave the bike almost on it's side for a while in an attempt to get as much oil as possible out of it.

Your total capacity is 1.5 litres. For example mine is 4.5 litres but I only ever fill up 3.8 litres, maybe 3.9. So when you change the oil you will more than likely need to replace less than 1.5 litres.

Best you can do is keep an eye on it and make sure the levels are ok when the bike is warm.
