ive got a 95 zr 580 efi, i bought the sled for 500, then ive put 2 new cylinders and wisco pistons and rings, i took the crank out and inspected it, replaced all gaskets and seals. sanded and painted the exhaust and cleaned and painted the engine compartment, replaced throttle/oil cable. the under carrage is perfect track is nice and has 96 studs. all fox shocks, is this sled worth trading for a 96 VMax 600 and a 90 polaris 440? the vmax only has 2600 miles on it and its in excelant condition, the polaris has high miles and in good condition. just need some advice tks
