Ok. i have a 99' zr440 sno pro, i got the sled with a blown motor, took it all apart and rebuilt the top and bottom, i removed the powervalve covers to clean and inspect, and there was nothing in there :cussing: , i have been researching all over the place and can't find any used ones, but i did find an update kit part number. but knowone seems to know what the hell is in it, the # is 0637-186 for the update kit. any help would be much appriciated, i don't think it will run to well with out them.
