Got an email form a guy that says this isn't off a 400F. Anyone know for sure what it's off of? I got it with a bunch of 350F/400f parts I picked up one time. Assmed it was 400F. No? http://cgi.ebay.com/ebaymotors/Honda-CB400F-CB-400F-gearshift-arm-and-pedal-shifter-_W0QQcmdZViewItemQQhashZitem20b717b575QQitemZ140510737781QQptZMotorcyclesQ5fPartsQ5fAccessories
Ah... I'm thinking early 90's Ninja. Makes sense now, the guy had a 400F frame with a Ninja front end on it.
