I got this 02 warrior on a trade i have done a carb clean, new spark plug, has new oil, k&n air filter, a white bros. exhaust and a 152.5 main jet, not sure what the pilot jet is cause the previous owner stripped it on the install. Now to the issue. I can ride this quad all day long if im below 4th gear. Once i shift up, say in a 1/4 mile race against the bro in-laws 350 rappy, the engine will shut down. I will let it cool for 60 sec. to 3min and it fires right up. Im wandering is my main jet too large? Its almost like i have to wait for the fuel bowl to refill before it will start again. Any suggestions would be very helpful. I can run it in 4th gear almost full throttle all day without an issue anything higher and its kapoot.:argh:
