1982 yamaha xj750 maxim

My son has a 1982 yamaha xj750 maxim and asked me to find out what kind of oil he should use in the crankcase...I went through about 10 pages of the forum and didnt find anything unless I missed it....Thank you

2.5 Liters of Castrol Semi-Synthetic MOTORCYCLE 20W-50 is what many of us use. Its not the best, but it's good and it's inexpensive.

It mostly has to be oil specifically for motorcycles, anything else will cause the clutch to slip.

The book calls for 20w-40, but that is hard to find sometimes. If you will be riding below 50 deg F most of the time, it's 10W-30.

There are a lot of other issues to address before he gets on the bike. Like brake shoe delamination, just do a searchfor delamination and you will find plenty.

 

thank you very much....he just called and asked me find out how to check the oil...we know where the oil drain plug and oil filter are..

 

There's a little window on the right side...it might be very dirty and hard to see the level, but a flashlight will help.

 

thanks..i found it...cleaned it off...and really cant tell what the oil level is even using a flashlight...hum..maybe it empty or too full I dont know...

 

If it was empty you would see a metal backing, it's probably too full, it's nearly impossible to tell if it's too full.

And the part that's dirty that makes it hard to see is the inside of the glass, btw.

 

ok thank you....im going to wait until my son gets here and he can look at it...

got another question for you....where is the best place to get a manual for this...I would like to get him one...

Thank you for all your help

 

Click on the "Everything XJ" banner you see at the top...it'll have everything you need.

 

A little engine degreaser on the window cleared mine up. You need the bike to be on its centerstand for several minutes before you get a "good" reading from the window though.

I use 20W-40, just takes a little searching.
