2009 rmk assault

[skyler]

i got a 2009 polaris assault and i was wondering if anyone else has had motor troubles with theirs around 50-55 mph it seems like theres a burb in the throttle just wondering if anyone else has gotten the reflash or if anything has fixed it.

There ahs been many posts on here with the mid range bog. Guys say its clutching if you are down low elevation (need to change weight). There has been numerous fuel mapping reflashes out there along with the cylinder head and piston update. Guys have been running aftermarket $500 programmers and they say that it is night and day.

I have a 2010 assault and found the same problem so I ensured that the fuel I run doesn't have any enthenol and plugged in the wire under the hood right by the clutch cover above the foot well and seemed to work.

Have a look at this link too
