Sorry if this has been asked before, I tried to search it out with no luck. Yesterday we went up riding on some extremely tight, muddy, root and rock riddled trails. I have a 2001 KX250 that I just picked up last week. The bike got hot in a few spots and I was spewing a bit of radiator fluid. Got back down to camp and topped off with regular water as a temporary fix. Im going to drain the radiator to avoid deposit issues and pick up some silicant free fluid. I dont have a factory service manual, so, where do you normally drain the fluid from? Should I just pop the hose off from the water pump? Is there any other drain methods? This is my first two stroke bike in about 15 years, so forgive me if this is a dumbass question. Also, Im gonna be ordering a Steahly flywheel weight, probably the 9oz, fairly simple install?
