I test fit the side covers and fitted the breather box.  I covered it with a section of inner tube to hopefully prevent any contact vibration. Sandblasted, painted and installed the sidecover mounting brackets. Thanks Charlie for the photos.

Tank and side covers fitted. Itís a little weird looking having G5 badges and T3 tank seat and bars.  Iíll stick with it a bit.

The fuel cap needs to be fettled, fuel light new installed, brake rebuilt and installed, gauges installed, throttle fixed and installed, front forks fettled, everything checked for tightness. Etc.

Great progress on the bike!

Isn't it strange how the breather box just sits on the two rubber hoses- no mounting bracket or tab so it can be secured to a frame tube. But I guess it works.  I'm off to buy hose clamps to install mine today.

Back around '70-'71 the Ambo breather box did have a bracket that secured it to one of the distributor bolts. On V700s, the fuel line crossover bolted to a stub on the top of the breather box.

 The gauges are the perfect combo of black print on a white face with a slim red pointer. And a just right sized digital display at the bottom. Beautiful!

Thanks Berniebee. The gauges are really designed for single use so Iím having to split wires if I want info on both gauges. Once itís set up I might try to water jet a custom plate. This one from MG is great for sorting but not quite what I want.

Slow progress. I have finished wiring the gauges.  Drilled the gauge plate to fit a mode button for each gauge at the bottom. Also installed led idiot lights for oil pressure, turn, alternator and high beam.

Almost done with this bike.  I had to tear it back to the flywheel since I installed the ring gear backwards. All that is left is installing a Dyna III, sorting the throttle cables and test firing and riding.

Groover - my apologies for the deviations. I have all the stock parts so I can bring it back to proper spec if necessary.

The bike looks great, well done!

The Dyna III came in today.  Great instructions and easy install. More importantly a big fat spark. I custom built throttle cables for the Domino throttle, checked all the nuts and bolts and fueled it up. Here is the first start:

https://youtu.be/3FqY6K9jvZY

It ran great around the block a few times.  It was my first ride on a big block.  Very smooth and torquey and I instantly liked the heel toe shifter.  Iím really going to like the bike.

There is a lot of sorting to do and I need to install the front fender, retorque the heads, adjust the carbs etc.

 I feel a little empty when I finish a project.

Is it the quick pull double cable Domino throttle you have? I have that one two and found that it has a tendency to go out of sync after a while. I guess when you have two throttle cables moving back and forth every time you turn the bars they will creep a little bit. And never the same amount. I think I will go back to a single cable throttle and a splitter at some point.

"I feel a little empty when I finish a project." - You can always start a new one right away :grin: Or have several in the backlog, that's what I do. Then it feels great when one is finished, then on to the next one after!

It is the quick pull Domino Rick.  It works fine now. I had to build custom cables for it, which will get old if it tends to break them. I use the stock cables and cut them back a bit and solder in the adjusters and nipples that fit the Domino.  I do have a very nice 1977 R100S and a 1973 SL125 waiting for restoration.  I usually take a few months and get some maintenance done on the running bikes. I also have most of the parts for a VW dune buggy build that Iíve been putting off.

Then it should be the same as I have, It is a bit hard on the throttle hand even with light springs in the carbs. But I have kind of gotten used to it. I don't think about it much apart from really long rides.

I made my own cables to fit the throttle as well, I haven't had any problem with snapping the cables, but it tends to work itself out of synchronization after a while. But works fine other that that. Maybe it is only mine that does that.

Well done, and congrats! Just did my first considerable mileage weekend on my '79. 687 miles over 4 days and one of those a very spirited 156 miles on Kentucky twisties. What wonderful machines, and mine's not 'fresh' like yours is. I imagine you're gonna love it. Cheers!

Thanks and great ride Kidsmoke. I canít wait for a long shakedown ride.   Iím still sorting. My list right now is:

Crab the frame AGAIN because I forgot to install the front gearbox oil seal and itís leaking gearbox oil from the bell housing (DUH).
Sort the neutral and oil pressure idiot lights.
Figure out why the new reg/rec is not putting out voltage.
Install the front wheel speed sensor pickup.
Sort a rear drive oil leak.
Sort sticky front brake light switch.

All in all not a bad list.
