300 overheating
With both the waterless, and water coolant, within a few minutes I could hear the coolant boiling. It sounded like popcorn popping inside the radiators.It seems to boil within about ten minutes, oddly enough it does not seem to make a difference if you go fast or slow. The bike kicks over really easy and rolls smoothly. Nothing feels like it is dragging in the motor or the chassis. I did make sure to bleed the radiator on the waterless and the water coolant. It did not help.
Somthing big time is wrong, I have never seen a bike get this hot so fast. Within a few minutes, back when I had the waterless stuff in, it didnt blow out but I could hear it popping and boiling inside the radiators. Water does blow out so I know the cap is working. All 3 rad caps we had did the same thing.
I looked at the water pump and it looked great. No pitting, no trash, impeller looked great. Took out the spark plug and worked the kick starter, impeller spins fast. All of the hoses were free of any obstructions. I kicked it over a few times with the spark plug out, the motor spun freely and the piston gradually slowed to a stop. It did not abruptly stop or slow down like somthing inside was binding up. I tried to grab the impeller with my hand to keep it from turning but couldn't, turns very strongly. I wrapped the rad hose that sits on the pipe with the heat wrap and another hose to shield it from the heat. I have not been able to run the bike to test it. I wish there were a good way to check the water flow with the bike running.
