So as a few of you may have read, I bought an 06 450. 2100 bucks and a hand full of problems. first cams were off 8-10 teeth each, fixed that, . changed sparkplug/ pilot to 48 and cleaned carb out. So I have a few problems now. It has a terrible hanging idle and just bad iddling habits. first it wont idle consistently, then when given a little bit of throttle, it revs up really quick and then hangs for a long time, I fix the hanging by touching the kill button which settles it. To add to this problem it gets HHHOOOTTTT!!! very quickly!! to quickly. So Im going to take the carb off tonite and check a few things, AP bladder is it in right position? and the carb slide. I need help knowing which way they go...Now about the thing getting hot. I think I am going to change the coolant, I should have already, I KNOW! . One radiator is slightly tweaked at the bottom, SLIGHTLY. Ive seen worse and they still work. So what should I check? the entire motor gets hot, the rads get hot, the header is hot 6 inches from. I just dont know. The coolant is my first guess cause its the easiest to do. But I think a bad impeller and deeper problem on the clutch side exists. I noticed that the idle settles out when I pull in the clutch, it slows a very tiny bit and smoothes out. sooo help me please! My 07 WR runs fine. I bet there is a serious problem with the valve seats since the valves were so far off. I think im going to take the head off any second now just to check. thanks for any help, any more details needed just reply back!
