Power addiction head install

[coolx2]

Just thought I would post up a short write up and few pics of my head install.
First I siphoned the coolant level down below the head. Undid the thermostat and coolant temp sensor. Then unplugged the det sensor. Disconnected a few other things just to get them out of the way.First pic is what it looked like all apart. Then I replace all o rings and seals. 2nd one is head ready to go on and 3rd is with the head and can all ready to go.

Man that head is pretty!

Just put mine on yesterday. Love the way it pulls now!

 

[coolx2]

Yeah sleds ready to go and the ground is brown and its raining here on the east coast. I need to move.

You don't wanna look at pics from here then lol

Did you have to run race fuel? I'm at 10K+ 85% of the time so I'm hoping I don't need any race fuel. I haven't put my head on yet and I'm wondering if I should run a little av fuel (110 lead) the first time out.

Fittings

This is awesome. I was just getting on here to ask a question about this install. I installed my PA head tonite also. MY question is, the fittings that you remove from your stock head, there is a 90 degree elbow coming off what would be the PTO side of the motor. In your second picture that elbow is pointing right at the temp sensor, i had to actually point that elbow up at about a 45 degree angle to get the hose not to rub on the temp sensor. Is yours the same way? or am i missing something? I had to also use a screw type hose clamp to tighten that hose tight enough since it was now at a different angle the hose wouldnt seal up with just the spring clamps. Let me know if you had problems too or if im missing something obvious? I tinkered with it for a while before just pointing it up

from what i under stand the 13.6:1 is good with quality 91 6000 and up
thanks for the pics i'm putting mine on tomorrow
let it snow !

this just in ! tropical storm hitting oregon snow level 6500-7000
grass drags anyone

 

[coolx2]

Yes I had to turn the elbow up about 20 degrees so that the hose would not rub on anything. I replaced the spring clamp with a new one,no leaks yet but I'll keep and eye on it.

I am in Alaska. I live at 30' elevation. I unload at times literally next to the ocean and run up to 8k Feet. Most riding takes place between 1500 and 5000. With that said I chose to run with the lowest dome Brad offers. I've got the 12.5:1 Head so I dont have to mess with avgas or race fuel. Coming off a highly modded edge, I'm getting used to running pump gas again. Running this head here at home today at 30' elevation on 90 octane pump gas (best Ak has to offer) I had no det issues. I will tell you this though. I was having det issues until I threw enough weight it. I run a 2011 163 pro. I am running 68g mtx weights and a 60-40-36 helix. Stock secondary spring. I ended up with a slp blue/pink Primary spring and 3 grams in the bellies and 3 grams in the tips. Even with the 6g's of rivets, the green/pink would hit det in the mid range. So, point is, with this head the motor revs quick. Just because you are getting a det light, odds are you are just hitting the rev limiter and not having a fuel issue if you are running the right head for your elevation. The tach on these sleds are slow to respond to instant changes. When clutching, make sure to use your recall feature. Play back a pull after you make it. Odds are you will see much higher numbers on it than you did by trying to peak at it while climbing. Btw, I am still turning 8300 max rpm even with all that weight. I'm gonna leave it for now til I get a chance to run it on the mtn at 3-5k'. Should be right around 8100 up there. That is my goal.

I ran into the same thing. because of how it tightened up, I wound up pointing my 90* nipple below the other sensor. Plenty of room to point it either above or below, just get it tight and make sure to use teflon tape on the fittings when installing them.

i didn't think the check engine light even came on when these hit det, they just pulled timing without any indication? polaris stopped flashing the light when the motor saw det b/c every time someone saw the light flashed they would call the the dealer wanting them to fix it, when there really wasn't anything to fix. my 07 mod would flash with det but i could also hear it when it was really bad. but the check engine light does come on when you hit the rev limiter and will cause it go into limp mode if its bad enough. i'm guessing enough det would also cause the sled to go into limp mode.

Yep. Mine was hitting hard enough that the it went into limp mode. Look at the speedo and it read Det... No engine light but det. At that point you need to turn the engine off and recycle the the computer. Sure wish we weren't water skipping yesterday. Everytime I hit the open river, I would over rev and hit the det and go into limp mode

 

[ziperhead]

whats with the brake disc?

Compression?

Wondering what head your running and if you checked your compression after the swap.

Im running the 13.6 head and checked my compression after the swap and seeing right around 125-7ish cold

Not sure if you are serious about the water skipping, but you probably need more weight. What do you need to do to get out of limp mode?

Unfortunately, I was dead serious about the water skipping. Several open water river crossing to get to one of our favorite playgrounds. Had to tow a dead one back out there too.
And yes, I have since added 2 more grams of weight, and went to a primary spring that is 20lbs lighter on the initial and that seems to have gotten the det out of mine. The spring was the big one. Think Im still gonna need more weight to get the r's down to where I really want them. Won't know for sure til i get a chance to get it back up on a hill and in the deep.
As for resetting the the det once bump it, you simply have to shut the sled down and restart it. Basically reboot the computer.

I want to hear how you got the dead one across the streams.

 

[theultrarider]

Look close. The pro is on a rope behind the dragon that is on the water. Just hit the water with a little more speed than solo, but the biggest thing is to not slow down on exit and get slack in the rope allowing the towed one to sink. Need to have a smooth take out. I've dropped 6-8' tall banks when hitting the water towing a dead one, just need to be smooth and steady. And have a nice exit run out area. They actually tow quite well on the water.

what happened to the pro? and are you running an pcV with your head? any pipe? if so, what map do you have?

No controller and no pipe or can... For now. May add a pipe in the future. Think I've got the clutching real close on it now and the fuel seems to be fine. Looking forward to getting some miles on it this weekend.

Not sure what happened to the pro yet other than an engine issue. 2000+ hard miles on that one and it's been solid.
