    Cool Yamaha wr500 wont start

    Hello everyone,

    I recently purchased a yamaha WR500D waverunner 1990. It started yesterday, but since then I cannot get it running. The engine is turning over good, Ive choked it still no luck. Any advice would be greatly appreciated.

    Also my battery which is brandnew got weak from trying to start it so many times without success, is this normal?

    1 more quick question, What is the oil fuel ratio for this model?

    Thanks for any help,

    Brendan

    Hello Brendan, welcome to the site.

    For your machine to run, you need three things. Spark, Fuel, and compression. You need to determine what is missing from this equation, and trouble shoot from there.

    Knowing what I know about Yamaha, I am going to guess you have a problem with the stop switch, killing the ignition, and giving you a no spark problem. Could be most anything though.....

    "IF" you have a defective battery, low voltage will cause a no spark situation. Never assume just because your battery is new, that it is actually good....

    With quality oil, you are fine at 50:1 ratio. You can go 40:1 if you want some added safety.
