Changes oil and filter - bike sounds different

[tingus]

As title suggests, I changed the oil and filter earlier on today and now the bike sounds deeper, more jerkier and feels like less power. Anyone know why?

I use Halfords Motorbike Oil 10/40 and a champion filter.
First time I done this bike and put in about 4.8l of oil all the way up to the top line.

I've used Halfords 10w/40 and either Suzuki or champion filters and never noticed a change in how the bike sounded after.

Has the bike been stood for a while or used regularly up till the oil change ?
Has anything else been changed at the same time ?
Hopefully nothing serious

same as Seth Ive used Halfrauds 10/40 a few times with no issues

To be fair, I've not really used the bike much in the last 3 months, just too cold. But I have been on it couple times, had to call out the RAC as my battery died last week and could not for the life of me bump start the bugger. New battery sorted that.

Just seems odd the engine sounds deeper and the other stuff I mentioned. Wonderes if I put too much oil in as I did put it to the top line.

I do find though that in cold weather the bike doesn't like it very much, had it before where it's a little more jerkier last year.

Interesting you mention too much oil. Back in the 80's certain Suzukis in the open production class were just faster than so many other bikes of the same model. It was later found that one thing was they ran them with a lot less oil.
Not saying you should.

Just to confirm we are on the same page, this is the oil that was used https://www.halfords.com/motoring/motorcycling/motorcycle-oils/halfords-motorcycle-engine-oil-part-synthetic-10w-40-5ltr

I had an incident when the aprilia  rsv Mille came out 2nd gen I bought one new,took it back to dealer I purchased it from for its first service around 35 miles away from where I live.first service done and when I'm riding home the bike starts missing and basically running crap,different sound and feel to the ride .when I pulled up at home wife says your bike sounds awful (yes even she noticed)when I got off the bike there was oil all over the rear end of the bike plus a strong smell of petrol,,,,,turns out the trainee mechanic serviced it and seriously over filled it with oil which in turn blew back into the air box then all over the swing arm ,hugger area,just saying could you have overfilled it your 14 as it sounds similar symptoms to my experience,,,,,by the way the smell of petrol was he'd split the fuel line when lowering the tank back down,,,.

I never get more than 4.5ltr in mine after an oil n filter change. It's worth rechecking the level now it's settled.

It won't be the halfrauds oil, I've used it in mine for the last 70k (I changed to it at about 55k) so it's good enough for these lumps.

@tingus
That's the stuff through it looks like they changed the packaging again as it used to say semi-synthetic.

Same as Hooli. Mine is over full with 4.8 ltr after a oil & filter change.
I would definately remove around 400ml or so, and get it to the mid level and do a comparison. Sure it will make a big difference.

When measuring 4.8 liters in a 500cc measuring cup, the level was always below the top line. Switched to a much larger measuring cup (kitchen thingy) and the level was above top line. Next change I used "4.65" liters with that large cup and ended up even with the top line. 4.5 would have been better. Next time it's back to the small cup.

Okay awesome, I shall let out some oil later on in the week. Won't be using it till it's warmer anyway.

I shall report back! And thanks

[grog]

not at all sure on this one. our 15w40 is in a tank. digital read out to 2 decimal places on supply gun. i always use exactly 4.8 litres, have for years. totally level with full line after sitting all day, tiny space just above it. no probs with any performance issues, 5k later oil remains exact same level, thats with bike on centrestand, flat ground.

[Sweaty]

I am just going off the 5 ltr container it comes in, so no accurate figure Grog. Oil level should be checked with bike on both tyres on level ground. I get my son or wife to sit on it & check. Not sure how much difference it is with the back up on the centre stand, but wouldn't think it would be much though. Might be worth a comparison when I get home today.
