I am new to this website and was wondering if anyone could help me with some troubles I am having with my RMK 900. I just bought this sled and it has only been rode a few times, pry less than 200 miles, over the last two winters in IA. It had always started on the 2nd pull and idled just fine until now. Put new gas and new plugs in. Got it on the lake and started riding. Seemed like it was a little boggy, but figured it would come out once the new gas went through a while. Then without the throttle down even a little the sled would die, even after riding for quite a while. It was running descent at 40-50 mph, but when I would put the hammer down, it wouldn't really react how it should. When it was almost out of gas, the sled started riding awesome. Going 40, I could punch it and it reacted amazing, like it should. Could get the skies off the ground and it would just fly. Then I rode it again a little later, and it was back to being really boggy and not reacting worth a crap. I was wondering if anyone could give me some advice on what to check, or do you think the motor just needs a good cleaning after not very much riding over the last two seasons? Thanks!
