Really nice job. I'm inspired by you and others who take something seemingly a goner and resurrects it to something really beautiful. When I saw the pics of the timing gears with all the rust I was amazed you didn't chuck it as undoable. Congratulations. A wonderful job.

Thanks. It just took patience. This year I bought a '79 CB750F that had been left outdoors in East Tennessee environs since 1999. And that was after POs did smart things like break cam caps, replace cam caps with incorrect ones, break cam chain adjuster lock bolts, swap 36mm leading axle forks into 35mm trees giving it ~3" trail. Oh, hoge blobs of Bondo on the tank and 3 lbs under the tail.

I took it for a ride today - 27 miles no problems, running and handling great. Fixed all the mechanical issues (that I've found), but decided NOT to pretty it up. A true rat-bike! Now that I'm retired, this is what occupies me. I learn new things, and really enjoy working on the machines. I'll sell the rat bike soon, hoping to get back what I put in. Then I hope to find a '79 GL1000 to restore.

Inquiring minds are wondering what you have in it ??

I trust my CB750 a LOT more than I trust the GL1000. It's a lot easier to work on plus you'll rarely have a coolant leak.

A little over $1400 not counting consumables. I did finally glue up a cowl underside for behind the seat, plus mounted a luggage rack that the PO threw in.



Rode it in to Knoxville last night for Time Warp Vintage Motorcycle Club meeting. My first time to be at their meeting (and join). Several old GoldWing friends there, and made many new friends. The CB750F ran fine! Only problem noticed was that the idle gets higher and higher as it warms up. I was barely able to get throttle increase from the choke full-out when I did the rebuild. Couldn't find a reason for it, and compared setup to photos in the SeanG document. So, I have to crank the throttle stop up a little to keep it running until really well warmed up then back it down, but seems to continue to creep up after that. I'll do another vacuum leak check soon with it both cold and again after about 20 miles of riding.

Also, mounted (just wedged in above the ignition switch) a cheap ebay digital voltmeter temporarily and connected it to the tail light fuse. Charging system seems great! Running at 14.1 volts over (I think) 3k rpm. Rode home with it turning dark, and headlight was adequate. Might need aimed just a little higher.

Next ebay purchase may be a cheap digital tach. I'm having trouble believing the mechanical tach - seems to be reading high while the speedometer is obviously optimistic by a bunch.

It's a good running machine, but I'm just too old to really utilize and enjoy it. Already on Facebook Marketplace and Knoxville Craigslist.

Common for these in line fours to increase the idle speed as they warm up .... 100 reasons why ?

Good deal if you have a working bike for that $$ ....

Make sure the cam chain tensioner is doing it’s job

Gord(no, I don’t know how to do that)Jones

The 1100F tensioner is better .... but rare ....

I've adjusted it once - after replacing the front adjuster bolt (for the upper tensioner) that a PO had broken off. The back adjuster bolts are a bear to get to, but at least the improved procedure doesn't have you doing it while idling. I still need to pull the carbs one more time to fix the fast idle, and when I do I'll do another adjustment on the vertical tensioner.

Very fine piece of work! Congrats!

Wonderful .... but we knew that didn’t we ....

Excellent!

2nd place in the Time Warp Vintage Motorcycle Club show at Honda Yamaha Suzuki of Knoxville today. Cold and rainy day, but some beautiful examples there and HYSK had a great crowd.

Congrats!
