So im pulling the motor right now..

[sks rider]

ok, guess is probably not accurate enough. The holes in the compfusion mounts are exactly 5/16.

ohhhh youre right. I had the wrong bit in the 5/16ths hole in the holder..

You should also drill out rear mounts on the motor and set some Heli-Coils in there. They are a lot stronger than the cheap threads in the motor.
Check the bolt length as well, Polaris is notorious for putting in bolt that only grab about 2/3 of the threads, making them weaker still and prone to strip out.

oh man. Thats something i dont feel comfortable doing. Just dont feel like drilling holes out on the motor. lol But ill for sure check the bolt length..
Would i use longer bolts?

if they aren't stripped don't fix em. Just make sure bolts are long enough and use a torque wrench to tighten them to spec. No taking any chances on over tightening and stripping those out.

I did it because I had to......went to torque the rear mounts down and it stripped out at about 10 lbs.
It does make the mount a lot stronger, remember, theres a lot of torque and twisting action going on at those points.
Its really simply to do, trust me. The kit comes with the drill bit, tap, inserts and insert tool.

Use bolts long enough to go completely thru the threaded tab on the motor and have no more than 1/4" - 1/2" of bare threads sticking out....you have to be careful that the injectors don't rub against the threads on the bolt ends.

The local napa has the helicoil kit. Its 30$.... Not sure what to do here. lol

its really a PITA to remove the motor on the 7/900 IQ sleds, because you have to take SOOOOOOO much stuff off of them just to get at them.

IMO though, take as much stuff off as you can because it makes it that much easier in the long run. Take your time with it, don't get frustrated.

1. Drill out the old threads with drill bit provided
2. Use tap provided to make new threads
3. Use insert tool to thread a helicoil insert into threads you just tapped.

4. You now have a stronger 3/8" thread set to put your motor mount into.

Don't forget to leave the two bottom bolts out on the re-coil cover BEFORE you put the engine back in. That way you can get the recoil off without pulling the engine again just for a pull cord.

Nobody has asked this yet, but have you taken your old mounts and checked them to see how many of them are bad? Just curious because I am getting ready to do the same thing on mine as soon as a few more parts show up.

Old mounts are still good as far as i can tell.

Did you put them in a vise and twist them over?

Yup.

that's probably a good sign that you don't have other serious issues with your sled. I will bet money they are bad on mine. They angle of force exerted on the front mounts by the clutches and belt on the 05 is worse than the 06's.
