Would over tightened or over adjusted power valves cause my temp light to flash the code for the servo motor lock and cause it to be a dog after 75mph. Because my sled has been flashing the servo code at about 75 and I rechecked them and they were way to tight this time.

I dont think so but!!When the servo starts to fail the sled will speed up ok when slowly giveing throttle but will bog when pushed hard at around 60 or 70.
Over-tightening can cause the cable to pull through the end of the valves which may cause a symptom similar to what you suggested. I recommend checking the valve end of the cables out.
However, I am guessing that you may have another problem. Does your drive train from the secondary back spin freely? Are your clutches aligned and is the belt in good condition.

yeah the track spins freely as far as the secondary is working fine. How do you know if the clutches are aligned. It flashes the code at about 75 that there is a servo problem. But I readjusted the power valves and put it on the stand and of course it doesn't flash the code on the stand. The servo works fine on the stand to. Wondering if I put a different servo on it might be weak??

Yep that is your problem..if the servo can't open it will give a that code.

tight cables will stop it from working good.

lets go over this, you adjusted them and then rechecked after running and they are way too tight??? That means they were incorectly set and likely your problem.
When you idle the sled down under 900 rpm the servo will open all the way, you should have made a mark inside the housing with a sharpie marker and also marked the pulley. shut off sled and then go about adjusting the valve clearance to 2.5mm at the housing. You have to continually look at your mark because you can move the pulley and not be the correct clearance. If you didnt do this, then do it this way and readjust the valves, as if they are too tight that will definitely throw off the code and be the problem. I will gladly send you my extra servo but you may not have the correct adjustment and not need my servo. report back after you redo the settings and run sled.
I believe there is the procedure in detail on the site with pics, check it over and refresh your mind before heading out to shop.

It's pouring rain out here so I won't have a chance to test it out today. hopefully tomorrow. Another question for Mr.Viper. last year when I bought this sled. I pulled the jugs off to make sure everything looked good after I re-jetted it. There was a double base gasket?? I left it alone not knowing any better and replaced just the top one. Now after thinking about it, it was jetted really fat and had a gutted air box. It would foul plugs like crazy , so I put the stock airbox on it and jetted it stock. Never fouls plugs now. I'm sure this has nothing to do with it but was wondering why someone would double up the base gasket?? Maybe it's not a 700 but a 780???

It probably has the heads shaved and the 2 gaskets to improve port timeing.Its alittle late now if you have the moter put back together but you could check cyl diamiter/cc the heads.There is some theads on this in the search.
