What size is the stock main jet (2001 Polaris 90 Scrambler)

 

ours is i think a 385?? i can't remember right now... why do u ask?

 

Just curious, we ride at or above 9000ft most of the time and I have noticed it
seems to run a little fat at times. I have always started 3 jet sizes down from stock
and fine tuned from there for 9000ft. I bought this new from a local dealer and they
sell the point that they never sell a machine that isn’t already tuned to Denver
altitude (5200ft). Just curious if they truly changed jets or not and where I was
starting from.

 

.875mm It will have 87.5 stamped on it. Might be a 85
You will have to go to a mini parts specialist to get the jet. Most cycle shops do not carry it. The carb is a VM11 Mikuni

 

Thanks much!
