Hey guys, my 89 kx125 starts up fine and rides great while cool. After a while the bike starts to go flat - struggles to take off & then I notice coolent starting to come out of the overflow? Any ideas? Thanks...
I only recently bought the bike. From what I can see, the radiator is clean (I did flush it) and i is getting air flow. As for the top end - not sure when it was done. Just wondering if there was anything common about Kx125s and this sort of prob. I need to check the gas mix (make sure its not too rich and causing it to get hot), and also check the head gasket. Any other ideas??
