My 79 cb750k ltd cafe project

[cafeloco]

Hi, been lurking around on here for a couple months now and finally decided to start a build thread. I picked up two 79 cb750k 10th anniversary bikes back in august and am working on turning one of them into a cafe racer.  Im totally new to this so any tips tricks etc. are greatly appreciated.
anyway on to some pics

when i first picked them up


got it running which i think had some serious negative effects on the engine. when i went to change the oil it looked like a swamp. i think someone had gone crazy with that paint on gasket stuff or something.


this is some of what i wiped out of the oil pan


tried to pull the engines by myself VT style... didnt work


got my mom to help me and this is where im at now. the bike has to be done my mid april so there should be some pretty regular updates






I also have alot of parts for sale, check out my thread in the classifieds section if you need anything

Welcome! Looks like your off to a good start. Good luck and keep us posted. Is that a Su-mo I spy??

hey, I'm in great need of a good 79K Limited gas tank, is one of those for sale?

[Hoosier Daddy]

I might as well tag along, always good to have another build thread to watch in the next coming months.

You may want to disassemble the engine you plan to use. If someone used silicone sealer in there it can have serious ramifications for the lubrication passages. The silicone breaks off into tiny bits and plugs things up. I don't think you have to totally rebuild it. Just pull off all the covers you can and maybe try to flush it with kerosene or a cleaning solvent to get as much out as you can.  

Your mom's a real trooper! Glad you had someone to lend a hand. You can tell her she's tougher than a Kubota tractor!

[shinyribs]

Oh,my bad.   sumo=super moto

I am guessing you are a car mechanic by the way you removed the engines. The way to remove DOHC CB 750 engines is to put a floor jack under them. Then remove the bolt on frame tube on the right side of the engine. Then you can just roll the engine out the side. Then Mom can bring out cookies.

thanks for the input everyone!

alehman - im in charlotte, about half hour south of burlington. forgot to get pictures of the tank, ill write myself a note for tomorrow

rich - i am planning on using the engine out of the parts bike because its in far better shape and im probably going to rebuild it or at least do the gaskets

shinyribs - no supermoto unfortunatly

tools & alpha750 - i did remove the frame piece, and once i got another set of hands i used the jack method sliding the engine out of the frame and then dropping it on blocks. i didnt really know what i was doing so it was easier with two people.

on to an update, i built an engine stand thanks to a handy thread i dug up by tools  

[shinyribs]

No supermotoBut you do have welding skills/equipment...and more than one bike...stretched frame twin engine build??? Think about it HARD before you say no. If I can convince one of you guys to build one I wont feel so compelled to it myself

pics or plans for said stretched frame twin engine? i was going for the classic cafe but that does sound pretty  awesome!

[Hoosier Daddy]

Heh-Heh... you asked for it! I know there was an old drag Triump restored lately calle "Hog (Hawg?) Hunter" or something like that, but you think I can find it now? Here are some others...

F-ing A man! If you pulled off a twin engine bike that would be the coolest thing ever!

[cafeloco]

oh those are to cool! maybe the next build  

on to a little tiny update, moved both engines into the basement today, used this funny toy wagon thing to maneuver them around

[cafeloco]

some pics of the tank for alehman, if your really interested i can grab some more  

[alehman]

definitely interested. Any dents/paint blemishes? Rust, inside or out?

[shinyribs]

LOL. Love the wagon! And no,no pics or plans for the twin engine-all in my head. Right where it needs to stay.$$$...
