I've got the HD 929, and am looking to go with the 20B from the JC Cosmo and mate it with the 5-speed. I may only be able to afford the 13B, but either way, I'll be doing better than the 3.0 that's in it!
Oh, and JITB can do as he wiil, but I won't convince him to go rotary. LOL...I wouldn't have the distinction of being the only rotary 9ine around if I did.
