YZ 400

I was given a YZ 400 (77 model i think)...I dont know much about dirtbikes (i alway rode street bikes) but is this the type of bike you mix gas and oil for a fuel mixture?

2 stroke i guess/ what is the mixture if this is correct

Go to dirtrider.net, they have a vintage bike section there and someone should answer your questions.

Here's one answer, yes your 77 will require pre mixed gas. Buy yourself a Ratio-Rite to use for getting the correct fuel/oil ratio, whatever it may be.
