I'll buy a X11, and install ceramic bearings as you indicated. Pipe 2045 + 192 it runs fine?
Once again thank you for your help!
Yep it will run great with that header and pipe combo. If you do have other pipes laying around you can always try those as well. The Orion 2058 works great on them as well. I have never been a big fan of any of the JP line of pipes on an RB but some people really like those pipes so it's all what feels best to you.
As far as parts..... RB no longer has the square stroke engines like the WS9 you have so basically all of the offroad engines except the K series are interchangeable when it comes to parts. bearings, rods, pistons, sleeves, cranks, and carbs will all work with one another. Of course the crank and the sleeve are going to change the characteristics of the engine if you end up using one from one of the other models.
