Ok i have a 1995 polaris indy 650 at least thats what it says on the cover of the sled. so im trying to figure out the full name of it. the title says its a indyst so im trying to figure out what the st stands for like storm or sport or what. i just bought it from someone else so thats why im trying to figure the name. and i dont know if it is the original engine or not because the engine has a label of xlt and i dont know if there is a polaris indy 650 xlt?
