Fan of Italian twins? Is that a Ducati 1000ss in the background? How do you like that bike?

I am. It's a ST4S I am using as my commuter bike. 996 with more power and less wrist pain. 1" more height in the rear to add some rake.
There is a guy selling a ton of very collectible Ducs and Bimotas here at the moment. If only I had a Lotto win...

FYI - this is the result of Jim's work on my head vs. the stock FA.

Nice improvement for a steetbike running a .400 lift cam.

My family has been sick pretty much of December. Kids gave their conjunctivitis to my wife who got hit extra hard, with some bad effects on her liver. She is still out of action. So, things are slow.
Got the rear fender and tail light assembly on, with much fettling.
Got the front wheel on and the caliper shimmed correctly.
But, the fender stay was rubbing on the tire on the primary side. 8mm clearance on the other side at the bead. My first thought was maybe the fender stay was flopped and needed tweaking.
But it looks like the wheel is laced 2.5mm dished too far to the primary side.
I suppose it will need to be retrued to center it properly.

Who laced it? I hope they left enough meat on the spokes to allow it to be corrected without replacing spokes.gortnipper said:

Me too.
The guy here in Auckland who laces pretty much all the classic bike wheels did them. When I took the hubs to him I asked.him if he wanted.to know how much offset they had before I broke them down: no.
The rear is supposed to have no offset, correct?

Spurred on by GP getting Rick's rolling, and since it is Boxing Day I made a shim from brass stock and put the problematic brake hub back together no problem. The frozen bearing dropped right in with a bit of red to keep it in place.
But, when I went to put it on the wheel, I noticed the tire was flat. A bit of air and then the tube cut loose. The guy who mounted it gave it a nice pinch flat.
Two steps forward and one back. And two for two on these wheels.
Merry f@cking Christmas.

Things haven't changed much around here recently and I haven't had much bike time.
I bought a new AN chain guard 06.1865 and there were two problems with it when I went to install it.
First, there was not enough of a gap to fit the thin head SS lower shock bolt and the washer I got from Rockey Point so I had to pull the speedo drive to get the bolt out to remove the washer
Grrr...
As I was installing it, I didn't see the guard push out the plug as I was on the other side of the bike. I saw it on the ground after. So, had to pull the speedo again and shave the dome off the plug so it was flat and would fit under the guard.
Double Grrr...
I didn't notice it does not have the cutout for the upper inspection hole blanking plug. The plugs appear on the AN 74 page for the rear wheel, but the guard on the 74 page is the older one not the 2a one to go with the brake plate.
Triple Grrr...
And I misplaced the front spindle clamping bolt.
Quad grrr...

I have a three phase Trispark alternator I bought a while back. I am thinking of mounting it here at the back of the battery box, since the Shorai I have is fairly small. Will it get enough air to keep cool?
