jag 440

Is that 440 l/c or fan cooled?

it is air cooled so i would like to put a bigger motor in it i got the sled for free and it is in mint shape the only worry i have is that it make a clunk noise when u mash the gas really hard but if u easy it on it doent make the noise .

95 artic cat zr 600 it seems like it is losing it prime if u blow into the tank it will run but if u stand on it and get the front end up in the air it will bog down and die but blow in to the tank and it will start bk up
