T80 engine oil change

Hello.

Maybe it seems dumb from me,but can somebody tell me the exactly procedure to change the engine oil to my T80.
It is the first time i have to do.

Thank you!

I am really surprised you have asked this question! Simple undo the drain plug at bottom of engine, drain the oil and refill with 850 ml (1.5 pints) of 10/40 engine oil.

Don't be surprise.Isn't there a oil filter to change or to clean?I don't have a user manual for my T80.
I want to use Ravenol mineral oil 20w 40.

There is a gauze oil strainer inside the drive side casing which has to be removed to gain access to it, it slides out and you wash it in petrol. It is only there to collect large particles. Probably a good idea to remove and clean it say every 10000 miles or so. I must confess I dont bother as I change oil every 1500 miles so it does not get blocked. Too much trouble to remove side cover and fit new gasket every time. You really should buy a Haynes manual as its covered in there. Yamaha specify 10/40 type SE or SF oil.

Thank you again,JohnW.

There is only Haynes manual to buy?Nobody have the original pdf user(or repair)manual for download?

Yes but Haynes covers much more than the handbook so well worth buying, plenty to choose from on eBay new and secondhand.

Ok,i will buy a Haynes manual.
Until then,can you give me some links with the original T80 user(or/and repair)manual?

Thank you again,John.

Today i made the oil change.It seems that the engine is running smoothly than before and change the gear better with 20w-40.The climate here is warmer than the UK so i find this oil(20w-40),better!
Hint:i swap the original drain bolt with a new one with magnet.It fit perfectly the Suzuki DR 125/200 magnetic drain bolt.

JohnW,thank you again for all your help!

CRISTIAN what is your country?

Here in Greece i use Bellray 10/40 semi all year time .

I tried Motul 15/50 once and the engine works worse.

Romania,Transylvania.
For now,is running ok,start ok,so i will see how will running.

My T80 was imported from Greece about 2 years.

Have also bought a magnetic drain plug from Hayling Motorcycle Spares https://www.ebay.co.uk/itm/AFTERMARKET-MAGNETIC-OIL-DRAIN-BOLT-SUMP-PLUG-YAMAHA-T80-T-80-TOWNMATE-83-96-NEW/282916308313?hash=item41df204559:g:yL8AAOSwepJXXP1D
Came today so did an oil change and fitted it. Old plug was getting a bit rusty and needed a new copper washer

You are in the north and reasonably in a more cold weather.

The SAE 10/40 is for temperatures from -10 to +40 degrees Celsius and SAE 20/50 for 0 to more than +40 .
I do not know if you are running the bike at such a low temperatures or you save it during the winter.

True.
I use my T80 only 3 month:june,july and august,maybe a part of september.That's all.It's a "city-summer" bike for me.
