WOW! Depending on what year it is it might not have very many of them but all of them can be dangerous if your not familiar with that particular bike. LOTS-O-POWER! Hang on and shift up from the very bottom.

found out its older than i thought its a 1979 YZ400 NOT a YZ490. So im sry guys for the wrong year. but hopefully i can still get some help when needed. should have never stopped riding. forgot how fun these things r. also Do i need to mix the fuel in this bike or straight gas. dont wanna mess anything else up. ive had a bike but i just rode it thats all Pops took care of the rest. oil fuel and all that stuff. Tryin to get used to the mechanics of these things.Hands on is the best way to learn

I would mix at no higher ratio than 32:1 which is what Yamaha and other Motorcycle Manufactures recommend.

If you find an oil that recommends less than 32:1 mix it according to the Oil's recommendations but a blanket statement of 50:1 is not always the best.

Thanks

YIKES!!!! it would burn it down.... no lubrication for the piston / rings. I don't believe that the bike is oil injected or not?

Do you have a container that looks like it has oil in it?

Thanks
