Help with my New Purchase 1986 Tri Z 250. What oil mixture ratio for this bike?

[Mrporshe944]

Hi I'm New to the forum All the way from Northern Ireland! I have just purchased a Mint condition Yamaha 1986 Tri Z.
I used to own a Honda 200X trike many years ago when I was 16. I would like to know the oil mixture ratio for my Yamaha trike. All info appreciated. THANKS.J

I always run 40:1 on my 2 strokes.

Many Thanks.

when in doubt 32:1 is a safe mix for almost any machine
