changed oil filter and oil this winter got registered took out for first ride and started smoking and dripping off oil filter shut it off. Got it back to house by truck found out after looking at it that it was not the filter but oil lines old and brittle and wet. Changed oil lines had to take a few things apart (took front wheel off and air filter tube also had to disconnect a few coolant hoses and lost a bit of coolant) replaced with water put things back together and fired it up and ran it for a while water temp light keeps on coming on now before it didn't what could be the problem(s)? how do i tell if water pump is circulating coolant? coolant is not leaking out any where and is not puffing white smoke anybody got any thoughts on it. appreciate anything that can be said.
