I just picked up an 84 CBR 400F2 NC 17. The bike was laid down. Lot of plastic damage, but runs very sweet. Having a VERY hard time finding any info on the bike. Don't know whether to restore or put a 600 motor in. If anyone knows the value of these rare bikes let me know.hvv44@yahoo.com.

 

No idea about the 400 but congrats and welcome. Post up some pics.
