Ok, I picked this sled up for 500 bucks, and it runs like a dream, but I am confused. It Says that its a Formula SP and says 470 on the hood, but from what I have seen, all the SP's were white. This one is Black. Can anyone tell me... what years did they make the SP's, and where can I get a manual for it, or service instructions. Are they the same as another model because I have the Clymer Manual for Ski-Doo years 85-89, but there is no SP's in it. What's the deal?

Here is a 86 formula sp

and a 86 formula plus

Post the first 4 numbers off the serial number and I should be able to tell you the year .

Its called paint,the previous painted the hood

They made them in 85 and 86

They are the basic same as the 84 SS25 and 85-86 Formula SS

But have outboard mounted rear shocks
