Oil Choices / smokey startup

Beta Ray Bill

Quick one for everyone.

I understand that high end sports bikes burn a bit of oil and that it's normal.

I've noticed though that my bike goes through about 1/2L of Oil every 1,000km's

The bike is fairly new. I'd had to top up oil before, but never by this much.

I remember though that this was an issue MOTOREX motor oil in my old KTM.
Very smokey on startup and needed to be topped up more than if I used something like Yamalube.

Has anyone else experienced something like this?
Currently there is AGIP 10W50 (As recommended by the manual in it)

Bike is an RSV4 1100

Also before you ask about smoke, the coolant level isn't going down

Seems like a lot alright - is there a lot of smoke on over-run or do you notice it when riding the bike? I wouldn't expect a modern bike to burn much oil between services - is there much mileage on your bike? 0.5L/1000km is what a two-stroke bike would use!!

About 7,000km's (it's 6 months old)
I think there is an oil consumption chart/spec in the manual, I'll give that a check when I get home.

Googling, reveals that V2 and V4 sports bikes are renowned for going through oil for a shortcut.

2010 CBR1000R was up to 1L of Oil for ever 1000 miles! :eek:

Most sportsbike engines are designed for performance which means low drag, this is accomplished by thin low tension piston rings which don't push on the bore as much.
Low tension rings means oil can get past them and be burnt.
Its just a fact of life with these engines.
That said try using a different brand oil, there might be a better choice for your engine.
Forums might be a start but ultimately it will be down to experimentation as well.
New bikes will commonly use oil as but as the engine beds in more it might start to use less.
All engines are different and I have noticed that some oils are definitely better in my bikes than others.
Motul,Silkolene,Castrol and others are all options and may be better than the Motorex.

On rotax 1k aprilias smoke on start up can sometimes be the slipper clutch diaphragm or oil in the air box seeping past the baseplate seal of the throttle bodies. Not sure if that's a thing on your bike but worth a search. Other than that valve stem oil seals or rings.
Your yokes are known to weep oil from the rear cam cover to header which shows no drips but does see oil consumption.

Change to 15 50 semi and see how ya get along.

When I bought my blackbird she was tight and used oil as she only had 1600 miles or so up. I ran mineral 10 40 and spun her up and down revs without load for 600 mile and switched back to semi synth. She's bedded the rings in and does not drink anymore, makes great power on jogs dyno too.

Check the spec... Up to 1L of Oil per 1,000km's is acceptable :eek:

I double check my mileage and top up time.
I'm burning about 350ml per 1,000km's (roughly)

Wow, burns more oil than petrol, lol (obviously not). At least it's not considered a problem. Phew.

and they say two-strokes are a thing of the past, eh ?? 😉
