Does anyone have a 325 or 330 cylinder head off their machine? I have my MOSE with the 330 engine that I can't get to run right. I am afraid I put the 325 head on it rather than the 330 head. There isn't a part number stamped into the casting.

All I can find is a few markings on the bottom side. They are different but I can't tell from them what the head is supposed to go on. From the measurement that I have tried, it appears that the combustion chamber is different between them. I don't have the tools to correctly cc the chamber so I am trying to figure it out another way. Any help would be appreciated!

I have a 04 sportsman 500 HO that won't start. The battery is new. It won't do anything. I can pull cord start it that's it. After getting it running by pull starting it, lights, winch, instrument cluster won't work. Thanks in advance

Hi ,read through as much as possible on fan not cycling on and off and can not figure out my problem . New thermostat ,no change ,new temp sensor on cylinderhead ,no change , old rad had a bend on bottom so replaced rad and hoses with a good clean rad.new antifreeze .fan cuts in and will not shut off unless i turn the key off and then it shots off .If i disconnect the temp sensor the fan cuts in as it should if i put a little cold water on the old or new sensor the fan will shut off . the machine does not seem to be running hot and i can feel the temp change in the rad and the hoses as the thermostat opens and closes . when i throttle i can see the rad hose neck drop and seems like good circulation . It seems to me that the thermostat is set at a higher temp than the fan so the fan will always run . never checked the resistance the switch but new and old switch are working the same .hot light is not flashing . I can feel the right side of the rad getting hot then cooling off .Any suggestions would be appreciated ,thanks.

Howdy!

I have a 2013 850. I am sick of the heat blasting my legs and my feet getting sprayed every time I go through a little puddle. I noticed the newer models now have block offs now.

Has anyone made anything for the older models to block the heat and spray?
