I am fixing a smashed up 2013 PRO RMK 800 ive replaced everything in the rear including new tunnel, suspension and a few other parts that got wrecked. The only problem i have ran into is the speed sensor. i have no where to mount it, on the end of the drive shaft where 99% of all polaris snowmobiles speed sensors are mounted the PRO RMK is an open ended plate its not cone shaped where the magneto mounts into. if you look on the parts diagram polaris has it doesn't show any where to buy a mount or where it goes or anything. even in there parts diagram it shows that plate open not coned like all the other models show is that an error on polaris's part? I'm wondering if anyone can take a picture of the end of there drive shaft and show me where the magneto mounts? The guy at polaris told me that i probably have an after market design thats why its not working right, but the sled has 50.4 miles on it the motor looks brand new and the track still has the sticker on it if any one can help i would greatly appreciate it, i would like to get this sled sold before spring lol
