Hey guys, I have a 2001 polaris 800 rmk that i extended the track out to a 156. it came as a 151 from the dealer but the guy i bought it from shortened it to a 136. So me being a little heavier needed a longer track. So its a 156 now and it runs great but, when i go up hill it feels like my track slips or it hit my tunnel or something. Could be the drivers slipping (i hope not) or its just hitting the tunnel. any ideas on what this is or how to fix this?
