Yes, it will void the warranty!

Power...yes, I've seen first hand how well the SDI responds to the Cudney Pistons and Head. My buddy installed them on his '05 SDI and it made huge mid-range difference. He had roughly 5 miles on his sled (post kit installation) and would walk away from my stock '05 SDI in the mid-range....and he stated that he never pinned it. I think he has roughly $1K in Mod parts...Cudney primary clutch kit, Pistons and Head, Hyperlite secondary clutch. He's running a 121X1.75 Camoplast.

I WILL BUY A CLUTCH KIT ON MONDAY! DYNAMO^JOE...where are you?

I say clutch it first! Ride it and then decide if you want to Mod the motor, simply because I think it's the biggest bang for the buck and will most likely NOT void your warranty. Also...I don't think too many people are Modding out their SDI motors.

It will void your warranty but I believe it is safer than the stock head because it runs so much cooler. I wish I would have bought mine when the sled was new.

I put a cudney head on 04 600 ho a few weeks ago. Though it is not an sdi this head made huge improvements. I raced an 800 Zr this weekend stayed with him out of the hole and stayed ski to ski with him till about 80 mph. After that he pulled me by about 1 and 1/2 sled. But it was a close race and made him think a little. This head will help your sled through out the whole powerband. But you may need a clutch kit to adust weight. Because when you add horsepower you need to then put that power to the ground. And more than likely it will void waranty

I've got my 06 SDI set up with a Cudney Head, Cudney Clutch Kit, V-Force 3 Reeds and Dynoport Pipe (into stock can). Made the sled a whole new machine.

If you need anything Cudney I've usually got almost anything you need right in stock.
