Just purchased a 2007 renegade 800 and it went into limp mode within 5 minutes of riding. I checked the rad, hoses, coolant,bleed air and check thermostat. So after all that I removed the water pump housing and noticed the water impeller isn’t rotating when I start the bike. What could cause this. I also notice the shaft that the plastic impeller is attached to is rotating and when I turn by hand I hear a clicking noise. any help would be greatly appreciated. Cant wait to get this thing running.
