2000 yamaha 2 stroke w/ issue

southern approach · 11-13-2008, 11:36 AM

when running the motor at almost full throttle, the engine boggs down and goes to idle speed at around 5000 rpm.you have to stop go to neutral to get it to go again.i have changed fuel filter, fuel lines, fuel check valve on motor and a bunch of other stuff.problem is still there.any ideas.

Is this an fuel injected or carbs. It sounds like something is putting it into rpm reduction, or an o2 sensor issue depending on theengine,,,,,call me and i will talk you through it,,, or you can bring it to me and ill fix it for you,,,,:usaflag

fuel injected

that is an ox66, that engine has a 2 speed fuel pump, this could be an issue, or an o2 sensor issue, this is where i would start,,, again, call me and ill talk to you about this,, maybe send you in the right direction,,, and if you cant figure it out,, i would appreciate your business,, thanks...:usaflag

I think it would be best for you to call and get guidance if you really want to try and tackle this. I feel that it would also benefit you to have someone check it out and tell you what the problem is. Then you can decide to repair it yourself or not. It can be one of your fuel pumps, an O2 sensor, blockage, several others like Kenny said. At least call and discuss it so you can have an idea of everything you will need to look for.
