Hey everyone,
Sled is a 2011 Pro RMK 800 155, 1700 kms, MBRP can. Just bought it and took it out saturday in 3 to 4 feet of fresh. On the trail in we had some problems with bogging at every rpm and rough idle, I am running 91 from the pumps with ethanol. Changed the resistor to the non-ethanol plug and it ran a lot better, got rid of the bottom and middle end bog, but still bogged around 8000 rpm every once in a while.
In the alpine it would pull 8050-8100 for about 10 seconds, and then fall on its face and consistently drop til idle if I kept it wide open, felt like it was running out of fuel. If I got off the gas and then put it to the bars again it would go for about another 10 seconds.
Near the end of the day, the sled had a trouble starting hot, would catch but idle very rough at low rpm. Then got stuck, shut if off and the sled would not start. Pulled plugs and it appeared to be running well, had spark, could smell fuel but plugs were dry. Two hours later in the dark it finally started up after pulling it over WOT. Ran well 30kms back to the truck.
Sooo, been doing a lot of reading, and I don't where to start troubleshooting. Everything from injectors, TPS, pipe sensor, fuel pump, ground connections, exhaust valves, clutching - where do I start? Can I do a resistance test on any of these sensors? Or do I just have to replace them?
On the tach it was only pulling max 8150, so I don't think I am hitting the rev limiter, but I know these tend to be slow so next time I am out I will use the recording function and check to be sure. Also no codes or engine light. But the parking brake light did get stuck on a few times during the day, could be a rubbed wire and a short?
I am running 62 gram weights @4500-7500 feet, dealer said it was a toss up from 62's to 64's at this elevation. Just had a new pipe put in and new fuel filter.
Any input would be greatly appreciated. Thanks in advance!
I was really hoping I wasn't going to have problems the first day out with my Pro!
