1990 polaris indy 500 sks

chaser886 · Nov 18, 2009

I was wondering if someone could help me? I have a 1990 polaris indy 500 sks. I have seen many websites say that it have a 133 track, but i have also seen places say that it also could have a 136? can someone please tell me what it is? or is there a way to measure to see what length the track is?

stock?

If it is stock it should be a 133". I have had 2 of them. Some put 136" on them. Some were able to absorb it with the adjusters, some moved the suspension back 1.5", some put rail extensions on them. If anything in these areas looks "non-stock" you are probably a 136"

Count the number of slide rail windows in the track. Standard pitch is 2.52" from tooth center to tooth center on sprockets. If you have 53 windows you have a 133.5" (2.52 x 53 =133.5) track. 54 windows = 136" , 56 windows = 141" , etc.
