Ok, finally gettting around to my C78 that's been waiting a long time...... Not the best condition bike I've got sitting around (6 Dreams here) , but I have chosen her for various reasons.... Anyways, I dropped the engine off at my friendly rebuilder today (who used to work on these things back in the 60's), and he'll sort that part out, I get to do the rest ;)

Anyways, this bike will be a regular rider - club runs & to/from work once/twice a week, so I need it to be reliable & also keep up with modern traffic, and as low-maintenance as possible To this end, I'm doing the following:

Bored to 338cc, Bigger inlet valves from a CB77, Camshaft from a CL77, carb is a NOS CB77 L side unit. Should hopefully get up & move a bit quicker ;)

Electronic ignition, care of Bill Silver. Stainless mufflers, replicated by a guy down here in Victoria that sells 'em to Bill ;)

LED lighting is also planned, to take some strain off the charging system, and to experiment a little, I'm thinking of powder-coating the whole bike, rather than painting...... this will be durable, chaep & easy, and the newer low-nylon content powder-coatings are very glossy, like paint.... Anyway, still thinking about that one....

Pics to follow ;)

looking forward to the pics!!!

Hi,

I flowed the head, and made the left and right intake tube exactly the same.

Rob, any thought to fitting a dual carb head from CB or CL?

Twin carbs won't fit in a Dream frame, without hanging them outside the frame on custom intake runners.... I want this bike to look stock..... It should be a fairly torquey little thing with these specs, I would think, a nice road bike.....

However, I am contemplating fitting a twin-carb head to the 360 deg bottom end & fitting it to a CB frame..... alledgedly it makes for a VERY torquey engine.......

That's what I have heard also from someone who did it years ago with a CB...claims he re-pressed the CB crank for 360 and rotated the cam.

I know it wouldn't be asthetically correct, but I wouldn't mind it as much if I picked up 5HP or so and some more torque.
Might be easier than me losing 40 pounds!
