2010 assault engine issues

[Flange509]

800 update

Ran mine this weekend(08 RMK Dragon),ran good but not very strong on top, only getting 8050 rpm's.Changed the belt and it woke up pretty good,up to 8350 rpm's.It is running rich at low rpm's but the midrange is stonger than I remember.Got a total of 180 miles and am pretty happy with it,just need to lean it out a little and it would be good.
I could get it to stumble at around 6500 rpm's but only on the trail and then it was more of a hiccup than anything else.

Tips

Are you guys running the right wieghts,because assaults come with weights for the mountains and that would make a big difference, was just in cooke with a 2010 assault and a updated 09 and both ran awesome!!!

Who did you get yours from in AK?

What octane rating is your premium fuel? In my 08 manual it says to run 91 octane. I only use 91 octane and still put in a little octane boost for personal peace of mind. Are you leaving the mapping wires unplugged or plugging them in?

You are in to something here...remember to use isopropyl based fuel stabilisator when use non ethanol based premium fuel.. to aviod ice bulid in your fuel system ! this is important to do ! to aviod engine faults and power lost

And plugin the wires.. after some break in ..
