I have a 1998 suzuki ltf500f 4x4. It runs great, idles fine, starts right up but i have no rpm increase after 1/2 throttle. I am a decent mechanic and have been working on bikes and 4 wheelers for over 20 years. This atv has a diaphram operated throttle. I am unfamiliar with trouble shooting one of this type. I rebuilt the carb with a kit. Like i said it runs great just no top end. Can anyone guide me in the right direction? Thanks

 

I Have THE Same Problem could you tell me how you fixed yours the fourwheeler runs fine and I cleaned the carb but after about half throttle it acts like rev limiter kicks in

ps if there is any way that you
could help it would be greatly
appreciated thank you
