700504's ultra-secret project F
« on: March 30, 2017, 11:16:04 AM »
Well I've always been terrible on documenting progress on my project bikes, let alone posting anything to the forum. This is my fifth rebuild, hence why I'm calling it the 'ultra-secret project F'. It's my first F model and boy-howdy it's a mover. Since we've got some good weather in the northwest; it's time to share.

The details:
-1977 cb750F I pickup for trade for a cb650 motor
-Torn seat that I reupholstered with ebay cover
-Seat trim, storage container, headlight bucket sourced from the forum
-Ebay: nos turn signals, head light ears
-Side covers from the one and only FrankenFrankenstuff!
-The engine was garbage with scored and pitted cylinders, rusted through stock exhaust, torn up crank bearings etc
-New valve guides and keepers, port on the head, rings, cylinders, crank and big end bearings, new clutch
-Had to replace the pistons and rods with some other old ones I had (the piston pins rusted inside the pistons)
-Had to swap out the cases since the originals were thrashed
-rebuilt oil pump
-Delkevic exhaust (best decision of my life)
-GSXR rear master cylinder, rebuilt stock front master, new pistons and pads and replaced a few of the lines
-I ended up completely rewiring it and replacing many leads and re-pining some of the connections, as well as redoing all of the alternator wiring
-Running the early style round top carbs which I fully rebuilt
-I then some little icing are all 8 finned tappets and points cover that I found on ebay for $30 if you can believe it
-Did a bit of painting on the headlight ears, side covers, engine and seat cowl but left the tank stock in the same condition as when I got it
-I made a Daytona style shift cover with the cutaway for the front sprocket
-I know I'm probably omitting a lot on this list that I might post later on

Big thanks to the forum and especially all those who like the kooky late model f's

Love the F's.  Great looking bikes right from the factory.  :)  Leave it up to a bunch of guys like us to mess that up.

I have the damaged cases, and the damaged crank shaft left.

Lol! I'm always crossing my fingers on people's first posts with their newly acquired project. But a few posts down the frame rails are gone and the cafe seat is already installed!

I used to hate them myself, over time I grew to like the looks. Lo' and behold I found myself seeking one out to put together as a stock bike.

I honestly look forward to the day I find a complete stocker that doesn't require a molesting.  All of my projects require a bit of work, restoration pretty much out of question.

I know the feeling, I was so happy to find this one even though the condition wasn't the best when I came into possession of it. Most of the ones I find have the frame hacked or tank ruined or mix matched parts, so I put them together 'the best way possible' with what you get.

Looking good!

Post up some info on the GSXR rear master conversion. Sourcing that is one problem many F'ers face.

I'll post some pictures a little later, very easy conversion, I'll try and draw up a blueprint for the mounting bracket I made.
