New Boyesen RAD valves - RAD85F-2

[Sled-Parts.com]

We have the new Boyesen RAD valves that replace both the cage and the boot on all XP800R's.

PRODUCT INTRODUCTION:
For 2013 Boyesen Engineering would like to introduce an all-new Full Valve RC2 Series Rage Cage, designed to increase overall horsepower and throttle response in 2008 - 2013 Ski-Doo 800R sleds. Boyesen's new Full Valve Rage Cage has been crafted to eliminate the need to periodically change your stock intake system's rubber intake boot due to delamination. The Full Valve Rage Cage system is offered as an upgrade to the current Half-Valve Rage Cage system, which allows use of the stock rubber intake boot. Both the Full Valve and Half Valve Ski-Doo 800R Rage Cage options perform the same while increasing horsepower and response. The major difference between the Full and Half Valve options is that the Full Valve design is a leading solution to the problem of intake boot deterioration failure; a leading cause of lean-condition, and possibly critical engine failure in Ski Doo sleds.

So hasn't the rad valve been all aluminum construction since like 2002? I thought that was the advantage over the v force.

Depends on which model. The valves for the 800/800HO twin and 600HO have always been the one piece design. In 2008 the design for the 800R motor was only the cage design and you still had to use your stock boot (Part number RAD85A-2). New for 2013 is the new one piece design for the 800R (RAD85F-2) which replaces both the boot and the cage similar to the design for the 800/800HO's.

The 07 800R uses the REV style reed kit (RAD84-2)

I bought them....

I just installed these reeds in my 2009 renegade 800r. Heading up to the UP this weekend for a test run.

The reason I bought them is because they replace the stock rubber intake boots and reeds as a whole, in one piece (as seen in the pics).

I wish I had taken pictures of the install but it was not a walk in the park. I would rate this install a 6 on the F-bomb scale. These ski-doo xp chassis are tight to work in. Here is kind of a breakdown of my install (high level). You should refer to your manual for more details.

1) Remove all stock parts (air box and components, carbs, intake boots and reeds).
2) Purchase roughly 1/8" shorter reed cage bolts (M5). The 12 stock bolts are too long. If you elect to skip this step, you risk stripping out the holes as they will bottom out before you tighten the cage down (not good - don't ask).
3) Loosen the tower brace. If you don't know what that is, you'll find out when you TRY to install the pto side RAD valve. Not tough, just one more thing to do.
4) Tighten the 6 reed cage bolts on both RAD valves.
5) Hook up the far coolant line to the carb, not the TPS plug just yet.
6) Loosen the cage to carb rubber boots on the Boyesen. If you don't, you'll never get the carbs in as there is no room and the Boyesen RADs do not "flex" like the rubber OEM garbage intake boots. And trust me, even with them loose, you'll drop a few f-bombs getting the carbs wedged in past the tunnel hump. Once in, you'll see ski-doo's XP chassis has indentations for the float bowls....that shows you how tight things are! No worries, once in you're fine.
7) Then tighten the Boyesen RAD to carb boots. Two clamps per side.
8) Plug in your TPS connector.
9) Install the rest of the parts (refer to your manual)

Overall, I really like them. I am looking forwards to testing them. I will not share jetting yet because I have not tested my setup. In my opinion, they are worth the $300+. It's just a matter of time before the stock rubber boots crack....then a potential burn down.

I got mine in and love them so far. The only issue i had was the 3 screws didnt quite clear the inside of the jug. Other than that, they fit great

It sure beats having to pay around $90 each for the OEM skidoo boot......
