need a little help on what oil I should use in my crank case. its a 1988 lt250r with vforce 3 reeds and a complete fmf exhaust. I had taken the entire bike apart and haven't touched the engine for a while. all help is appreciated.
I use amsoil 4 stroke synthetic wet clutch 10w 40w in winter and the 20w 50w in summer.
I use shell rotella t 15-40 diesel oil works great even in the cold and it's cheap always have it laying around as I use it in my truck too. It's wet clutch approved
Some folks use an SAE 30 oil, others use ATF. Just don't use any synthetic motor oils or anything with anti friction additives as this can burn out your clutches.
So you say no synthetic oil, so the ams oil 4 stroke use is not good. Or do you mean synthetic motor oil.
ATF type F ! Works great change frequently.
Atf will work good if your seals are up to par and you should change it every ride or so.
^^ this is true my shift shaft seal is in need of replacement and the ATF leaks pretty good while sitting from it.
lots of good oils out there, the only thing i suggest is NOT using BelRay Gearsaver. Caused my tranny to start pitting and rusting.
