So far it is pretty good and it isn't even really broken in yet.... we'll see how much life I get out of it.
Mine is a Jim Hottinger set up also.
I find the RPM band similiar to old OS RG engine. Good club motor but needed to extend out the top more so I went up on the CB also on it.
I am going to replace the bearings in the N21BF and use it daily and save my two RB's for the major races.
