One beautiful bird my friend.....

I decided against painting the tank (actually painted a corresponding stripe then stripped it off). The tank is too beautiful in its polished aluminum brilliance.
A lot else has happened. I installed new FAC dampers and progressive springs in the front suspension. I painted the lower forks, as you can see. I've delinked the brakes, using a 15.8m kawasaki master cylinder to drive the front calipers. I will use the same rear caliper, or at least try to. I am waiting for more brake line to get the rear operational.
I found a Lemans mk 2 rear fender and seat, which you can see attached to the bike. The seat is a bit worn. I am looking to replace or restore it eventually--there is no rush here for me.
I wired the bike and wrapped the harness. All that is left for electrics is to wire (and fabricate entirely) the dashboard and front turn signals.

Thanks NCA!
This week I got my gauges on.
They were easily mounted with some cups from Speedhut bolted to some simple bar stock run along the upper triple clamp. The Speedhut gauges are very nice, really have nothing but good things to say about them so far. Very simple to wire up.
I've also started the tuning process. I retimed the bike and verified that the advance mechanism is working correctly. Running the bike with the carbs as I got them showed lean carburetion (by examining the plugs). So I swapped in 142 mains and 265 atomizers. The carbs were already equipped with 60 pilots. I left those in.
Power is OK all around, though I am hoping to get a bit more out of her.
Groover:
Nice job with the instrument cluster. I do like those gauges, will definitely consider them in the future.
What size were the main jets before putting the 142 in? Curious what you end up doing to gain a little power. Did it have more power before upping the jets?

Thanks Groover. Just have to find a place for some idiot lights for the dash. Were I to do it again I would buy one of the all-in-one units, containing a speedo, tach, and idiot lights in one gauge.

The old mains were 125. The 142s seem to help the top end but I think I'm running a bit rich on the transition phase, just off idle. Might try lowering the needle.
I also tried the stock 50 pilots, but in that case idle was running incredibly lean--spitting and backfiring. Perhaps my float level is a tad low, about 24mm, but in either case replacing the 60 pilots yielded a smooth idle.
I installed a Dyna ignition, which according to the marks on my RAM clutch is timed correctly, but that is another variable to consider. I tried advancing by a few degrees but that caused idle to suffer.
Right now the G5 feels about as fast as my T3, perhaps a touch slower, which isn't bad as the T3 recently got a brand new top end. I think I might be expecting a bit too much from the old girl.
Isn't tuning these old bikes fun? :laugh:
Antiquar:
Took another crack at carburetion yesterday. Reset both floats to 23mm, kept the same 142 main and 60 pilot jets. Dropped the needle to the 1st notch. Running rich at idle but pretty damn good everywhere else. Might try 50 pilots next.
