Nice day today, so I took the CB750F for a loop over Norris Dam. Running great, I think. Accelerates much harder than my GoldWings but vibrates a lot more. Handles well. Everything mechanical that I could find wrong has been fixed except the speedometer error, which is ~ +10mph @ 55mph. She really smooths out at ~5000 RPM (~55 mph by GPS) all the way to ~7500 RPM - the highest speed I took her. Didn't have the GPS then, so I don't know how fast that was. I was wearing ear plugs, and above 55mph all that I could hear was the air intake and wind noise. So different than a GoldWing though! I like the ergonomics with these Euro handlebars. Only a little 40 miles but the 66 year old body felt like I had done it on the GL1800. The original bars were identical to the GL1000 stock bars, and I always got stabbing back pains in 15 miles with them.
I guess she will go on Craigslist soon. She was always meant to be a winter project that I intend to get my investment back from, so I'll let her go for $1500. Not bad with it running well and new tires and chain, GL1000 front end, all sorted. I doubt anyone on here is interested but if you know of anyone wanting to do a custom CB750 but not needing to fix mechanicals - or someone that wants a "rat bike", let them know.
