coolant temp sensor mod

Well I posted a while back on using resistor 4.7k ohm plugged into intake temp sensor to trick ecu into thinking cool air coming in thus increasing fuel and ignition advance. Well the coolant temp sensor trick does the same thing but way more aggressive. By putting in a 4.7 ohm 1/2 watt resistor in temp sensor plug and going into ecu "menu" by pressing rest select on gauge cluster. Number 6 is coolant temp and readings with resistor showed engine temp thinking it was 42 degrees F. This trick will make bike run in "warm up" mode and dump fuel. Its rich, really rich lol but at mid to wot I felt a new beast. When I came back and turned off the bike, 3 minutes later it wouldn't fire. Engine was warm and too much fuel made plugs wet and wouldn't start unless I held throttle open some to allow air to enter. Not a long term mod and not safe for full time as in your temp will read low and fan won't come on.
