 Where we race, the return roads all go left. I'll get it on the track one day. We race a Dragster and tow a trailer to 12 to 15 races a year so I have every chance to drag a bike along and make a hit.

 Thanks, the muffler is ridiculously long, Hondaman says top end will be good.

 It's maybe, the third 750 sold here, serial 14,100 I have the K0 airbox, wrinkle tank and new sidecovers but the gauges are k1. This engine is a ported and cammed K4 836 but I've purchased a correct #K0 motor for it.

 A Cone shorty would be about right. My wife likes that one, she always thought the shorty on my 76F made her smell like exhaust.
