Warrior Cutting Out - High RPM's
I am looking for some advice on my 2000 Warrior that is cutting out on the high rpm's. It starts and runs great at low rpm's. When I start getting up to high rpm's it starts cutting in and out. When riding hard it loses power when I need it most. It does the same thing when I am revving it up real high in neutral. I have tried everything I know so far.
I replaced the carburetor with two others from my other warriors that run great. Still happens. This rules out the carb ( I think). I replaced the fuel tank to make sure that it was not a clogged fuel valve or breather hose. I have run it with and without the air filter. Still acts the same. I have replaced the spark plug.
Also, this bike has a Pro Circuit T-4 exhaust system on it. Could the exhaustr pipe have anything to do with this type problem?
This is driving me crazy and I cant imagine what else it could be. I thought for sure it was something to do with the fuel system, but I guess not. Any help or ideas would be great. Is there anything else that I can try replacing from one of my good running warriors that I have not though of?
Thank you all in advance for helping. Reading these forums have helped me before.
