FI and temp light on

Changed the fuel filter yesterday and fixed my problem but now when it gets warm the FI and Temp light are coming on. The FI light flashed 7 times once but when i shut it of and turn it back on it goes away for a while. It runs fine at top end but not running very good at idle. Any ideas?

That's the code for the ECT (engine coolant temperature) sensor. Check to make sure your wiring connector is plugged into the ECT sensor. The ECT sensor should be located right beside your sparkplug.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.
