Hey y'all,
Picked up a little 72 Yamaha DS7 250cc 2-stroke bike. Owner's manual suggests SAE 30W, 10W/30, 20W. Says "Where possible use two stroke motor oil for air cooled engines".
Not sure what to go with or where to find it-- have heard modern car oils are not the answer but all the motorcycle oils I see are labeled 4-stroke, and I've seen yamalube 2 stroke available online. Suggestions?
I also have a gearhead friend advising me to run some seafoam through this thing on the next tank, but I'm a little apprehensive. I've heard these older motors/seals are better off just living with a bit of uncleanliness, and I'm worried it's going to destroy seals etc and just kill the motor. Any thoughts?
Previous owner just said the main thing he did was use Stabil in the fuel tank.
Thanks!
