Hey all. Looking for help with my newly purchased used Brute. After i first start it up it runs great. After 2-3 minutes when I attempt a WOT run I can only get about 25mph out of it and a bunch of backfiring. Here's the interesting thing. If I shut it down and then immediately turn it back on and attempt a WOT run it runs awesome again for 2-3 minutes. I can only think of a couple potential problems and was hoping for some input. It's as if the bike is running off the fuel that is being pressurized at ignition turn on and then not by the ECU. I can hear the fuel pump running when I turn the ignition to run. I don't have an FI light on the dash. It is snorked but I don't know how this would cause these symptoms. It runs great by cycling the ignition when it's both cold, warm, and hot (while the fan's running). I'm leaning towards fuel pump because of how the condition goes away. If it were injectors or some other sensor (TPS) i don't know that cycling the ignition would fix those. Does the ECU "learn" anything in the first couple minutes of being on every time or does it just give a certain timing and fuel map based strictly on sensor input. I know there's two different timing maps for low and high throttle, but again I don't think the TPS is the cause. Any ideas???? Thanks....and I'll get a sig up soon just joined yesterday and goin out to load her for a ride today, limp her around the woods.
