I own a 2000 300ex and I hear that all the 2000 models needed the throttle adjusted. Ok so I did it. Took cover off and made it where the threads show more and where there is very little play left in my throttle. Well I get my first ride on it and Im going as fast as it will go in 5th and the thing dies on me. I check my fuel and it appears taht there is plent but I put it on reserve just in case. Later in the day with the reserve still on I think (not sure) it ran pretty good. I parked it for a while then got back on. Turned the fuel back on and was in secdond this time when it died. Could this be not having enough fuel or possilby some type of electrical problem or maybe even that I adjusted it wrong or something? Please let me know as I care about my quad. It could be me but it seems as though my rpms are higher than they used to be throughout my whole powerband. Do I not have enough play now or what? Should I put it back to how it was? Let me know.
thanks

I'm not sure what the problem is but I's sure of one thing it is not. It's not your throttle adjustment or it either would not rev or would not idle when the bars are turned. I would fill the tank & turn the petcock to run or what ever is not reserve. Some times the fuel looks adequate but is below the divider inside the tank on the reserve side.When you started riding again, some fuel from the reserve side may have slopped over the divider allowing it to run for an instant.
BTW, I found that the best & most accurate way to adjust the slop out of your throttle is to start the engineafter slipping the rubber boot back from the adjuster, and backing the adjuster out a tad while the bars are straight. Then turn the bars to full lock in both directions while the engine is still idling. If there is an increase in RPMS, you have adjusted too tight; back it off just until the idle remains constant. Of course none of this relates to your problem, but just as info for later.

 

Ok. Thanks. I may try that if it still dies after I add gas. But for now I think I may leave it alone. As for the higher rpm throughout whole powerband that coudl jsut be me but not for sure.
