78 CB750 CAFE Resto-Mod Build

Everything is back from paint. Here are a couple of pics of the Tank, front fender,and tail section. Still need to get the seat upholstered. I made a panel under the tail to protect the electronics and mount the tag. Probably won't get back to it till after Christmas. Should have a finished bike pretty soon.

I have started another cafe build using the tried and true CB platform. Tore the bike down just to discover the frame was bent. I have located another frame that is straight and will tear everything I need off the bad frame and start mocking it all up with the good chassis. I am going to use this tank from a CB550.

"I want a tank like yours !" ...couldn't find a CB550 with another like that style. Any idea what it could be from ?

Very impressive finish. Nice one.

Mossy21.... If I'm not mistaken the tank is off a CB500T.

Right you are about the tank it is a CB500T tank. I got it off ebay as a 550 tank but never really paid attention to it after that. It does give the bike a sleeker look though.
Thanks for the compliments.
Installed a Pamco ignition on the bike. Nice not having to deal with points. Still have a couple more things to do before I can get it fired up. Should be done soon.

Great looking build. When I was researching my mono-shock conversion I saw that the newer Husqvarna TE dirt bikes used a very similar shock linkage. I like the clean looks of that system without the linkage hanging beneath the bike. I wish I had found the CBR swingarm/linkage...

Anyway - how does that Koso speedo work - Is there a wired speed sensor? Where did you mount it?

It does have a speed sensor. I made a small mount on the bottom of the fork it can use multiple magnets for pickup. I used 6, one in the head of each brake disc bolts. I guess this helps with accuracy. I was also able to utilize a temp sensor located on the tach side, senses cylinder head temp.

Couple of shots from under the seat. All the electronics fit nicely. I wired in a newer style regulator rectifier from a 1980 CB750.
Battery is secured with a strap. I used a tail light converter to integrate the turn signals into the tail lights. The seat is secured by 4 locating pins and heavy duty Velcro for easy access to the electrics and the oil tank. Just need to tidy up the wiring a bit. details, details.

Painted and wrapped the exhaust system also installed new grips, levers and mirrors. I completely went through and thoroughly cleaned the carbs in my sonic cleaner. I re-jetted them and set all the float levels. Also mounted a choke knob on them just in front of the petcock. I may have to do some fine tuning, but I should be close on the jetting. Pretty much done with the build just need to fire it up and ride it.
I will take some pics outdoors soon and post them up.

where did you get the gauges and the switch from. Build looks great so far. really digging the newer front end.

The gauges are KOSO. I think I ordered them through Parts Unlimited. The key switch was just a universal 3 position switch, I made the aluminum piece that it mounts to also fit the top triple. All the warning lights are single LED's with a custom mount.
She is done. Fired up the bike and did a short test ride. Idles and runs nice. Good response off idle. Have a slight hiccup in the mid to upper RPM range, so I still need to make some minor jetting changes. Overall really happy with how this bike looks and feels. It rides like a modern sport bike with some old school flair. Just it time for spring.
