I'm not quite sure how to start explaining this, but I will do my best.

Sometime last year me and a group of guys in a vintage riding club decided to join the HAMB drags. The biggest hurdle is that it has to be 1965 or older to even be considered. Brit bikes were out of the budget as well as any American branded one. That left a 305 to try and track down. Luckily at a local swap meet we found a Dream in rough condition for the right price. Obviously this wasn't going to be the fastest bike to start with, but we liked the challenge. Everybody agreed that a supercharger would be our best bet, so we sourced an Aisin 300 from Australia and decided to build a ground up frame to hold everything together. Somewhere along the line we decided that our buddy's BSA would work better for the HAMB drags, and a cb350 motor took over the ca77 spot to make a nostalgic drag bike that would run at some local events. Since I donated the cb350 motor, the ca77 motor was given in exchange. We had already sold off the frame and other parts, so I decided building a road racer with a ca77 motor could be fun. Not many people use them for obvious reasons, but that I think will be half the fun.

Here's the bike before we took it all apart.





I really wanted to try and build a full racing chassis for this project, but I found a decent deal on a hawk frame and swingarm that just made more sense. Saves me fab time, and possibly puts the bike on wheels way quicker than I had planned. The frame just came in today on a Fedex truck, so I'm just about ready to start digging in. First things first I have to start putting some wheels and stuff together. I have a ton of cb/cl350 parts leftover from previous projects, so I am in hopes that a cb/cl front end will bolt up. I may get lucky with the rear wheel, but I'm doubtful of that until I can get the two together in the same room. I should have more info on that soon enough.

For the motor, I want to keep it's ca77 roots but hot rod the hell out of it. Big bore 350 kit, hotter cam, bigger carb, etc. I know it probably seems silly to even bother, but it sounds like fun, so why not? I should have some more stuff to post up tonight, but for now I will post a couple my past projects.









My current project bike is a tt500. Before I get too heavy into the ca77 I need to finish this one for a ride I started doing a couple years ago called the Ozark Mountain Scramble. I built the kz400 as well as the cl/cb350 (shown above) the past two years for around $800. If possible I would like to build the Dreamhawk for next years ride as well as hitting a couple track days at Hallett in Oklahoma. I'm not sure if that's a reasonable goal or not, but that's what I'm shooting for.

Here's where the tt sits right now. I've been redoing the rear shock mounts for a more street oriented setup, but still have some work to do.

Is it safe to assume I only need the valve cover from a cb77 to bolt the ca77 motor in? Were there any changes over the years? My frame number is cb77 312616, so I think it is a 63.

I went home on my lunch, and got a chance to put all of my parts I would like to use all in one place.

The frame has a couple chunks of 1/4" steel booger welded to the seat frame that should come off pretty easily. It doesn't look like the person got much penetration.







Then one peg mount welded in similar vain to the swingarm.



I'm not sure what to think of all these washers on the swingarm pivot.





I'm most excited by the fact that my 68/69 cb350 tank looks proportionate enough. If all goes well, this tank will be on the bike.





A couple pairs of cl/cb350 forks.



What's left of the Dream pipes.



cl350 front 19" wheel and a cb350 18 rear wheel.

I don't think messing with the cb350 will be worth the trouble, so I will probably track down a cb77 one instead.



The Dream motor. VIN code CB77E 110383

I can't seem to find out what year the motor is. Any experts that know a place to look it up?







And a pic of the whole pile. I think I am going to just weld on a different motor mount for the Dream motor to fit the cb frame if possible.

Motor is a 64. Washers on pivot to take up slack from missing aluminum peg mount brackets.

Thanks for the info. I think I am getting a better grasp of what I will need to get this thing functional, but sure there are plenty of new things to pop up. I guess that's the perks of putting together a basketcase together without knowing how they were taken apart.

You may have some bother getting the single carb to clear the frame tube. Normally these frames use a twin carb motor.

I've got the frame wrapped around the motor and the carb clears fine. I could still fit a decent sized filter or velocity stack by the looks of it.
