gears

I bought a 06 polaris 900 RMK 151 track. I pulled the cover to change the gears. I wanted to put in 19-43 gears.. It has 18-43 in it. how do these compare.

19/42 is the BEST setup you can run on an 06...but the ones you have now will work fine..

will 10-66 weights be better than 11-72 at 6000feet

Give some addition info such as Primary spring spec and power mods such as pipe for a better answer.

11-72 would be the same as 10-74 witch is for flat land for 6000ft you want 11-68 or 10-70
