My 1994 yamaha yzf 600g only starts with starting fluid.after, it'll rev to 7000 but no higher. if i let the revs below 3000 it dies. carb cleaning?

It sounds very much like your main jets are blocked. Did you soak them in carb cleaner overnight and run them through with some very fine wire? That will usually sort matters. The only other thing that would cause this is if your Cdi or coils were starting to die, but since it ran better before you cleaned the carbs I'd guess jets are your problem..

I thought i had a problem with my carbs. it started cuttingout when i romped on the throutle, but when i took it to a cycle specialist, they said the royal star had a Rev Limiter in it. it intentialy starts cutting out and back firing when I try to rev it too high. I\´m looking at getting the DYNA 3000 to customize the limiter. $270 bucks
Yamaha installed the limiter to lengthen the life of the bike, so this may be a long term bad idea.
I\´ll see.

clean the carbs, bubba.

Try cleaning out your carb, Petrol starts to form into a jelly after 3 to 4 weeks if you dont turn the engine over. Your carb is situated under your petrol tank. Hope this helps

that is the indication of the exup valve malfunctioning. it tosses the code of 7000 rpm for a few seconds on start up to let you have an indication that there is a problem.

You should measure the combustion ratio.Maybe piston rings failed.

are the carbs balanced correctly and are you sure that all of the jets are clean. if not try it, it might work. sluggish throttle response is normally to do with the carbs.
