550cc - Arctic Cat M9000

The flow rate is spot-on for my 2014 M9000, and the machining on the injector body looks clean. I've put about 150 miles on it since the swap and the throttle response is crisp.

Install was plug-and-play on my 2015 M9000, and the idle smoothed out immediately—no more hunting between 1,000 and 1,200 rpm. The 550cc flow rating matched the stock specs perfectly, and I've put about 300 miles on it since without a single stumble under load.

My 2012 M9000 runs like a new machine with this 550cc injector. The plug-and-play installation took me under an hour, and the difference in throttle response is immediate.
