I love them! Super high quality, the forum support on their site is great and they have a huge line so you can find a great engine for your budget. They hold their tune very well and run super fast. You can even get modifed by Rody Roem versions which all kick major ass. I will only run RB because I am that impressed with there product. Dont get me wrong, I like the mugens just as much, but I gotta give love to the RBs
 
Thanks for the reply and the great words about the RB's.
I just got one, (the entry level one 1003-E), and am currently taking the flywheel/clutchbell off my old one and transferring it to
the RB. I have a small gap between the clutchbell bearing and the securing screw at the end of the pilot shaft. This is giving me
some slop that allows the clutchbell to move a little back and forth along the end of the shaft. I don't think it should move but not sure what to do. Maybe shim the flywheel out some would take up the slack.
 
it is good to have a little slop, but not too much. about the thickness of a dime.
 
That's about what I have, maybe 1-2 mm. I added some shims on the inside. Some of those ultra thin ones and it looks ok. Again, Thanks for the input on the RB engines.
