Running horrible need help????

I put a new air intake temp sensor in and helped my problem zero. There goes another hundo. I've been playing around with the exhaust springs, rode the sled with the springs in it, pink springs and no springs. None of them really seemed to be better than the other. It will still bog out around 6400 to 6500 unless you pinch it and then it will hit max rpm, and it won't get past the bog all the time doing that.
I've already put a new tps and pig tail on, I guess the next step is to replace the whole wiring harness. For some reason I don't think that will help either??? Everything I try seems to go nowhere with this darn problem.
Anyone have a wiring harness they want to part with?
I looked at my motor mounts which are the stock 06 mounts. I couldn't see from looking through the side braces and underneath the throttle bodies that they were broke or any damage to them, but maybe I don't know what to look for. Could I have bad mounts or broken mounts that could be throwing the timing off???

Broken motor mounts should have no affect on timing. You can not tell without removing them. I just removed mine and looking at one side they look fine with just a line on the edge on one and on the other side you can see the rubber has let go all the way around. A couple of them I had to put in a vice and twist over to see that the rubber was torn.
Injectors
Hey Boozer, i feel for ya man, this kind of thing can be a pain. It sounds like you are having an issue when the sled gets hot. I am thinking you have an injector problem. I would pull the injectors and send them in to get flow tested.

I put in a brand new stator a few weeks ago, seemed to help a little bit but still having problems. I'm not a mechanic but I can usually fumble my way around things. I'm still thinking that it is an exhaust valve problem because the mag side valve is dropping back down when I hit the bog or that is probably what is causing the bog? I'm going to try to find a seal to put in the valve to see if that helps. Maybe it is loosing enough pressure through the sleeve, if thats even possible?
I'm going to try a few more things and if they don't help I guess I'll pull the motor and start with the injectors. What the hell its just money right!!

I am having the same problem. It ran great last ride of last year. Then I built my own intake this summer, replaced bars, hand warmers, and put on a new bumper. Had both clutches apart, cleaned checked and plugged off exhaust valves, set TPS. I was also thinking about checking the reeds because sled has 4500 miles and I dont know if they have ever been changed. (I bought it with 3500 last Feb) I thought I read in another post about a fuel filter issue that might be an problem. If anybody sees any correlations with what I did and what may be the problem please chime in. It just has me wondering because it ran so well last year.

Here's what I have tested this year:
TPS set and sweep tested fine put in a new tps and pigtail just to try
New stator
New intake temp sensor
Checked all plugs and wiring cleaned all post and applied dielect greese
Cleaned ex. valves and all ports
New bellows and gaskets
Plugged the ports, drilled holes, and inserted seals in the valve bodies
Checked reeds
Checked clutching
The only thing that seemed to help it was the new stator but I'm still having the same issue.
I have a complete wiring harness and an ecu off of a sled that was running fine so that is my next step. Wiring harness first then ecu just to see which one helped....if they help. If that doesn't help my next step will be the injectors. Man will I be glad when I figure out this problem, I'll keep you posted

Well I finally found the problem. I was going to switch out the main wiring harness to see if that would fix my problem. I was double checking over all the plugs and harnesses and found the mag side injectors were swapped. Can't believe I missed that all the times I had that sled apart. Explains why the the thing was running crappy after the dealer put the new crank and clutch on. So to recap, I was having trouble reaching max rmp she would bog out and not get passed 6200 rpm. I guess one good thing is I have a mess of spare parts now. Man is it awesome to finally have a sled that runs again. Put on about 60 mi yesterday and not even a hiccup, awesome feeling. Thank to all you guys for the help and good advice.
outstanding, congrats on the find and props for all your hard work...
now ride the hell outta that baby!!!
thanks for updating everyone.
