I have a 97 polaris indy 440, which has 5500 miles on it. I haven't repalced a part yet. But know I have a problem. It is losing coolant, and I can't find any place where it is leaking. I have filled it 3 times in the last 3 days with coolant and it keeps using it. Could I have A cracked cylinder sleeve. Also it loses all power sometimes and just won't move.
