Learned something new last week ... On both of my builds I just left the tip over sensor wired in. I figured if I ever rolled the buggy over having the switch there to cut the fuel off might not be such a bad idea. Last week I was driving my #2 buggy real hard on a motocross track. Some of the corners were the type that you power slide through in a full four wheel drift, but there were lots of cross bumps/ruts from the motorcycles that rocked you side to side pretty violently as well. Fun actually. But in doing all that I managed to trip the switch for the first time. Didn't turn the buggy over, just banged things around hard enough to trigger it. Well I always assumed that if it triggered by accident (like happened here) it would just trigger momentarily and then reset right away and other than maybe a brief sputter you'd keep right on going. Nope. What I learned was that on my engine (2003 GSXR 600) once it triggers it kills the fuel for good until turn the ignition off and then restart from scratch. So time to remove the tip over sensor. To do that you can not just jumper the wires directly, or just leave the circuit open. Some testing showed that the CPU is looking for 60k ohm in the circuit to allow the fuel pump to run. I ran several tests and found that 10k ohms up to 100k ohms will work OK. I had a couple of 30k ohm, 1 watt resistors laying around so I soldered one of those into each machine. I tested it (drove it) last night and this morning and it works fine. So on the GSXR (all of them I'd bet) get a resistor and solder it into the circuit if you want to bypass the bank angle sensor. Tim
