2006 RMK 900 purchased in 2010 with 1200 miles. Now has 1800 miles. We have had zero problems with it until yesterday.
Previous owner installed new Polaris crank and primary kit and SLP torque/push arms, exhaust, heads, air intake.
Sled was running fine until it stalled and back fired after about 30 minutes of easy riding up to our cabin. Started back up but was fussy, sounded funny, smelled like fuel was rich, had about half as much power.
Would not stay running without a little throttle.
No check engine light.
A video of start up and sound of the struggling/stalling motor is at https://youtu.be/KEFfntKDBfU
I honestly don't know much about sled motors in general.
Anyone have an idea where we should start looking?
Thanks so much,
Neil
