    Default Kawasaki ER-5 - oil site glass misting up during winter use

    I bought myself an ER-5 recently - regulator issue aside it's been a reliable workhorse so far. It had a full service mid 2015 and it's only clocked up a 2500 miles since, but as 18 months have passed now I figure it's time to give it an oil and filter change.

    I've noticed that over the past few weeks the site glass has gotten progressively cloudy. So much so, that I could barely see the oil level behind it. Research online suggested this is due to my short daily commutes and cold weather, not allowing the engine to get hot enough and causing condensation... This evening I put that to the test and took the filler cap off for half an hour after getting home. Lots of steam escaped and as hoped, the glass is much clearer now - a little emulsification remains but I should be able to get a good reading when I change the oil over the weekend.

    I don't have have a garage and keep the bike outside, so am weary of keeping the filler cap off regularly while exposed to the elements - are there any further steps I can take to prevent this from happening over the cold winter months?

    Take it for a nice long run more often.

    Short runs kill vehicles. It doesn't have to be that long. So long as it is up to temp then take it down the Mway for one junction with it in 4th, or just hoon it about on your local 'race circuit' right up to the red line. Once a month should do it. But I would do what Bob says on the day you change that oil.

    FWIW I'd be putting good oil into that, well not silly stuff, but the bang on highest right specced stuff. I mean the one with all the right specced codes for that Kawaski engine, not just the viscosity alone. Perhaps just for this one change, seeing as it looks like you're changing it <3k.

    Don't forget to redo the chainlube more often either....I used to waft a teeny squirt over mine after I got home, with the bike on the centre stand & running in 1st. About a 3 second job.

    I took a detour to work the other day and did a brisk 25 miles.... That didn't touch it, so glad that taking the filler cap off has improved things considerably. I'm guessing it will need a 75+ mile trip to clear up proper?

    My daily commute is 8 miles each way and only 30/40mph, so it does need a good run in all fairness... I'll take it on the motorway on the weekend and will do so more often - it's easy not to when I use the bike all week but I doubt pottering about in 3rd/4th all the time will do it much good long term.

    I've already bought some 10W40 s/s oil ready for the job. No idea on the brand but my local motorbike garage use it every day and sell it straight from the drum. I was thinking it's best to do another change ready for summer in a few months time so will chuck in some good stuff then. Chain is oiled about once a week, and it's been keeping nice so far... Was always a pain with my old XJR (had to use paddock stand) much easier with this bike. Also bought a can of ACF-50 which hopefully will keep the salt corrosion at bay - seems to be working so far!

    Thanks for the advice guys, much appreciated.

    Basically that.

    The moisture in the oil WILL burn off - but you need it give it enough time to do so. A 30 minute ride once a week (just take a long ride home once a week) should do it.

    NEVER oil the chain with the engine running.....




    I've met enough people missing finger tips to NEVER attempt this.

    It's just occured to me that the ER5 is actually watercooled (unlike the CB500 and GS500), so it could also be a symptom of head gasket failure.

    Is the level of coolant in the expansion bottle remaining the same from one day to the next?

    Or a thermostat failure.

    Nothing wrong with it if you use an aerosol and don't get too close.

    For the record, the CB500 is water cooled.

    Yeah you've pretty much had the answers. For every gallon of fuel you burn you create a gallon of water. Most goes away down the exhausts (which it will also rot if you don't get them proper hot by the way!) but some gets past the rings and if the oil isn't hot enough to boil it off it emulsifies with the oil to form a toxic "salad cream". Normally this is seen in the cambox which is the coolest running part of the engine so if you're seeing it in the sight glass your engine is good and proper clagged up.

    TBH if it's that bad your best bet is to change the oil now and start with a load that's not heavily contaminated with water already. Go for a run then leave the engine idling while you prepare to do the work. Get it proper hot. When you drop the sump plug just remember it can get to over 100C. But at least it'll be good and thin and should bring out most of the water emulsion. Allow to cool and refill with fresh oil. Use bike oil not car oil. There IS a difference.

    For the future try and make a point of giving it a good blast at least once a week when the weather starts to turn cool, maybe half an hour should do it. Consider changing the oil on a calendar basis as well as mileage. It's cheaper than engines

    I used to do the same as Ed. And I came very close to regretting it.
