mook13 Posted August 26, 2006 got a 2006 KX250F, bought it brand new, had 15 minutes on it from pro circuit. Rode it about 2 hours last week at hard rock with no problems. It ran about 174 degrees most of the day. Wash it two days later and tonight go to ride. Started right up , stalled and then took a little while to kick over again. Adjusted idle and it kicked right over. Let warmup, then it started to spew anti freeze from the over flow tube. The bike was running about 215 degrees then. Shut off, checked all the hoses, all were tight. Started again after refilling radiator. Let run, once it got to 215 it started to kick antifreeze back out of the radiator tube What is going on?

SCCRF450 Posted August 26, 2006 is it overheating at idle? that is kinda normal... did you drop it and maybe crush rad fins? So they cant cool? sounds weird, brand new bike Share this post Link to post Share on other sites

barch88 Posted August 26, 2006 Wait, you said it was a Kawasaki right? There's the problem. JK man...well, not really, but first thing I would check is radiator cap, replace that first, then if it still happens, we can go from there. Share this post Link to post Share on other sites
