MY 1987 yamaha pro-v WHAT IS A GOOD TUNE UP FOR THIS MOTOR AGE AND MODLE. AND HOW IT IS RUNNING ALSO WILL RUN LONGER WITH CHOKE ON .http://www.youtube.com/watch_popup?v...d:
I would start with a compression test first and new plugs. Dosent sound bad on start up but appears to be a bit rich with the oil mixture.Do you mix the oil or is it oil injected?
