Are you kidding, Dragon clutching issues? That's the pot calling the kettle black. Also, I have yet to hear about a single 08 800 crank issue.
I heard the Dragon is the most perfect sled on the planet...well except for the migraine of owning one!!!! and having to read posts like this guys
Question D8 fuel injection and running issues.
Ok Can someone tell me if the fuel injection on the new d800 has a closed loop system and what the parameter are that run it?
I did a lot of analysis this Saturday based on everything everyone is saying about fixing the mid range miss and this is what I found and why I am asking the question.
The sled run fine if my throttle is near wide open it will never stumble, hard to keep it there all the time.
I ran it down a wide somewhat straight trail and found that if I am running near 1/2 throttle and between 7100 and 7500 it will not run right, period, one cylinder seems to stop running. Once I got it in this zone the rpms drop to 6300 +or - . I squeezed the fun flipper to the bars while it's was running flat and it stayed flat, rpm's read 6250 on the nose with no fluctuation, which I held for 10 seconds to see if I can get the check light to come on, and it sounds like it running on one cylinder. Pull over check plugs; clutch side looks perfect, the mag side is all wet and oily. Thought maybe the problem is a bad plug, so I changed the plug and nothing changed and I can repeat the problem all day long. So sometimes I notice this poor running and sometime I don't because I don't alway ride in condition that I have this combination of rpm's and thottle position.
So... here is what I don't know. Is the fuel injection running in a closed loop at this point like most car system and what sensor would it be running off of or is it running strictly off a map based on temp, alt and throttle position?
Why is one plug wet? Can the system shut down the coil to one cylinder or does it only have a single shared coil like I believe it does. If it can't shut down one cylinder then it must be under fueling or over fueling one cylinder to create this problem. If that is the case is there a failsafe in the system to create this because I would think that under all normal condition the brain would be sending the same signal to both cylinders at the same time.
If there is a fail safe to crate this condition why does my motor think it has this condtion to create this? If there isn't a failsafe then do I have a corrupt map or if not then why isn't everyone experiencing this issue? From what I am reading and being told it is only a handful of sleds with this problem.
Can anyone else that is having this mid range missing repeat what I have found by trying to cruse between and 7100 and 7500 rpm?(around 1/2 throttle)
The dealer has checked all sensors and setting and can not find a problem and I’m getting a little short on temper waiting for Polaris to fix this there has to be an answer in here someplace that addresses these running issues. Maybe they need to give me a new Brain because mine is tired.

I haven't had to do any shaft replacing 30 miles away from the truck over six knarly hill climbs...
