Replaced crank bearings, new pistons and rings, cleaned everything, new coil , new throttle and choke cables, everything is all cleaned and back together was a lot of headaches and work the motor literally had rat dropping caked in it lol but it is back together still working on bugs needs cdi box and voltage regulator to run correct. seat needs to be redone. starts up if i heat up the cdi but she is getting there this is are 9th sled we have 8 running sleds lol this is are first yamaha we have ski-doo and polaris so we will see how it goes.
