Thanks for all the props and PM's !
I will be posting up the Evolution of this project as I build the sled with photos and descriptions.
I wanted to undertake this project to see what could be done with the 900 in newer chassis. I really like the look of the RAW chassis so getting this done is a natural for me.
I really like the WAY that the 900's make power... lots of low end grunt and the ability to just flat get up the hill.
POLZINHUNTER, I've been anxiously awaiting yours/COBE's front suspension developments... Those gems will be making it into the PRO-RMK build for next year (hope to get a 400 lb sled when I'm done).. Yep, this is the build you and I have been talking about for a while.
speedemon, Yes I'll be going with a 2010-08 RMK seat and the 2010-08 Tank configuration. Getting the fuel pump figured out has been a challenge... more on that as this project unfolds here. Not sure on the power plant yet... no 1140 in the plans though. I have a few choices on how I can build the 900 motor up what I want to add and how to control it. I've had the tunnel on hand for a while now waiting in the wings.
Houlster, I have been "horsetrading" for parts for a while now to get the needed items to build this sled... Plus a LOT of cash dumped on top, lol. It really is a lot of work, way more head scratching than I would have hoped for (the small stuff) and figuring out that I wanted to do the project in the first place. I have come to the realization that the 2006 motor will work in this application since I posted up that info you have. The steering post is the key here... and I got lucky...more on that later. You don't need a complete RAW chassis to do this, but that is probably the easiest/least expensive method in hindsight.
I'll be post up some interesting pics and more info as this unfolds over the next couple of weeks.
