Another Benelli Egg bike
cliffrod:
The plating is a nice touch, Jim. So many original fasteners and pieces on the older Italian bikes were dull vs shiny. Those look great.

Almost ready to start up the Benelli.
Mac D from New York State sent me a NOS head complete with guides! I reamed the guides and lapped in the new valves and it’s perfect. Amazing Mac had this NOS head wrapped in waxed paper from Cosmopolitan after all these years!!
Lots of small jobs completed over the last two days, fitted a throttle cable, it is a Venhill kit that I shortened to suit, replace the tach cable with a NOS item from William Kuhen, stripped and cleaned the petcocks, new fuel lines, I installed a Guzzi fender cable guide for the speedo cable, adjusted the drive chain, set up the carb for what is hopefully a good base point. I installed new points and condenser and set the static timing, new period correct high tension lead and a ‘pink’ Magnetti Marelli spark plug.
I flooded the crank case with 4 litres of oil and kicked the engine over at least 150 times, then drained the oil and refilled the crankcase with 2 litres of Castrol 10-40. I am getting a nice bright spark from the magneto ignition.
Then I hit a snag, no lighting or horn, I had replaced all the wiring but like the 200 Motobi I restored last year I initially kept the stock rectifier and regulator along with the convoluted wiring through the light switch.
After a lot of messing about I again abandoned the old reg / rec and fitted a full bridge rectifier and rewired the guts inside the headlight shell, mostly eliminating the CEV terminal block and wiring all of the lighting and horn circuits off the battery and feeding the new full bridge rectifier direct to the battery for charging from the two wire lighting coil.
I hooked up the 6v gel battery and as I had hoped I have a functional horn, brake light, head light and tail light plus high and low beam. I won’t know if the rectifier is functioning until I start the bike up but it should work. A good friend who was an electronic tech at the local university found me a rectifier to work and it cost less than $18! It takes two wires from the light coil and sends out DC + and -
The reproduction header and muffler fit much better than expected, just one slight modification to the header Janet mid frame.
I welded on a new tab for the steering damper and steering g lock, I thought I had made the correct shape but when I installed the steering damper I saw I had to redo it, careful MIG welding and touched up with Por 15 black paint.
I am contemplating making up custom rear sets for the bike, not sure wher to begin, perhaps modify a set of Tarrozi pieces?

I’ve been studying some of the different Ducati single rear set configurations lately for my simmering projects. I would think you could weld up very comparable parts that would look more period-correct than Tarozzi pieces.
Original period-correct Ducati/Italian fixed and folding foot pegs for rear sets aren’t hard to source. Making and fitting folding pedal for the left side so the kick lever will clear is the normal dilemma..

Good points Clint, I need to find some pictures of period Italian light weights to come up with some ideas.

After sorting out the ignition circuit I got the little single to fire on the second kick, sounds good, engine responds well to throttle. Stock 24mm Dellorto carb and stock energy transfer ignition

After starting it and letting it warm up a couple times the kick start made a pop sound and swung with no resistance, something broke in the pawl ratchet, the motor will need to come out and the cases split, luckily I have plenty of spare parts, its a setback but something that just takes some time to resolve
