1980 CB750 “Beavertail” Cafe Build

Nice progress. Be advised that by dropping the forks in the triple trees you are changing the bikes geometry. all things remaining equal doing this will decrease trail. This could make it twitchy and unstable. I would recommend running your rake/trail numbers to see where you are at.

 
I agree with what Doc said about your front end geometry. I'd also be concerned about the width of your front tire. A 110 is pretty wide and will give you very heavy steering. That along with the dropped forks could be very weird and potentially evil.

Thanks for letting me know - I'll check this out some more. I have some research to do!

Thanks for looking out - I may change a few things around after finishing up the build and running a few test drives.
 
Huge updates - the bike is done aside from break-in and minor things that I probably forgot in my build list. With the warm weather here on the east coast (and now half the MC season gone) I was chugging away at finishing this thing and getting it on the road. I’m posting all final weeks at once with photos and not a ton of word vomit. I’d be happy to answer questions anyone has with their own build but if you’re anything like me you just want to see the progress in short bullets along with photos.

Week 14 5/28 Wiring Craziness

Drilled holes in bars for switches
Started by loosely running all M-unit inputs
Took pieces of OEM wiring harness (mainly ignition side)
Wired everything one circuit at a time - gauge gave me the most trouble
Installed custom headlight/mount
Cockpit view

Week 15 6/7 Wiring tidy up + Tank Paint

Finalize all wire routing and testing
Tank and seat mockup for motivation
New Ignition coils and wires installed (not shown)
Tank primer laid down
Green Laid down - I chose to go with Porsche Forest Green Metallic. It looks almost black in the shadows and slightly green in direct sun

I test mounted the emblems and also plan to use trim liner around the edges to line the tank to "finish it a bit" this is the photo of no trim liner

Here is what it looks like with trim liner - let me know what you think!

nice but agree the back hoop looks like it will smack the tire on a bigger bump. other than that the colour and other details are really nice.
 
Not to dog pile but that shock to tail interference actually could be dangerous. Easy to check - remove one shock and then compress the other to see how much travel you have. Other than that I like the work you've done. Nice color on the tank.
