So i decided to change my oil today. Level has been half way up pipe since i got the bike. Emptied oil out and i reckon at most 1.5ltr came out! I had 4x1ltrs oil and as i poured my second ltr in the oil had filled the pipe! I put 3ltr in total in and ran the engine for 10 mins thinking it would settle once filter filled etc. Nope. Still showing as full. My queation ia do i continue and put another 700ml in and just ignore it or could there be a problem?
Don't know how much you know about these bikes but you are aware that it's a dry sump engine so draining is not per your average wet sump bike ?
If 1.5 litres came out and the oil level was fine before draining, then logic would say putting 3 litres back in has vastly overfilled the bike. If you use it like that the excess will likely get pushed up the crankcase breather and into your air box. Always go by the oil level and not quantity alone when refilling as you will never remove 100% of the old oil in a simple oil change. There will be pockets of oil trapped all over the engine.
Checking the level after refilling is a different method as well due to the dry sump. Engine has to run for a warm up period and then turn off and allow the oil to track back to the tank for a few mins, then look at the level. Your just getting it ballpark at first fill (about 3.7 litres with a filter change) and then top up after it has run. By the way, if you left lots of dirty oil in via only partial draining then your new oil has mixed with it and is now contaminated.
Hi and thanks for the reply. I ram the engine warm and then left drain screw off for an hour and filter also. Surely this will drain most of the oil if not all?? The oil level was going up and down before, if you can believe that, showing full sometimes and empty others. So you reccommend i drain the oil til it reads half in tube? On a hot engine after standing a min?
where did you drain the oil from, which drain plug did you remove ?
The one underneath oil tank.
There is a second magnetic drain plug just behind the oil filter on the crankcase which should be removed as well. Having said that I can't believe there would be anything like another 2 + litres in there. If it were me I would completely drain the oil (from both plugs) and refill to correct level.
You won't get 4 litres in there because things like cam chain tensioners are captive (like a cup) so oil gets trapped inside them. There will be lots of trap points that will contain oil that won't drain fully no matter how long u wait. If you get more than 3.5 litres in there from a full drain with an already oil soaked oil filter I would be surprised.
Thanks for the advice. Bike goes away tomorrow to Almeria so i really dont have time for more oil changes. Therewas a litle over 2ltr came out just measured it and 3ltr went i . Oil was jet black. I will drain to correct level an do oil and filter again when i get back from spain. Also when i spin the frot wheel it sticks at one pointSecond hand discs just fitted but trusted source could it be because i havent fitted new pads
Depends how badly it sticks, it's not unusual to get light rubbing even if everything is fine. Ideally you would want new pads because the old ones will have worn to match the face of the old discs but given the limited time you might have to go with it as is. Check the disc bobbins are free or the disc might not be floating properly. Push a suitable size flat blade screwdriver or similar head into them till it grips and twist. If they don't rotate freely, squirt a little lube on them (protect the braking surface) and repeat until they are free.
Couple were sticky. Now free. Thanks again for the advice. Just hope all goes well with it now! Oil levels fine also. Cheers.
