Oil tank installed, tore the only half-decent rubber isolator I had, so I made up an isolator from a long bolt and short section of rubber hose.

I did this on my old Mk3 when one of the isos broke. It ended up breaking off the tank's mounting bracket. :cry:

I've got 2 new isolators ordered along with some gaskets and a few other bits.
 
Folding right side rearset peg and re-shaped shifter a'la JPN. Waiting on left side z-plate & spacer hardware to mount rearset brake pedal.

Headlight mounted, front brake master cylinder overhauled; only brake hose I have is barely long enough.

The remaining pile is getting MUCH smaller...

I've already pulled over $600 worth of good used parts off the shelves and out of various bins around the shop. There would have been a stock set of footpegs and rear brake pedal on it already, but I sold them just a couple of weeks before I got this bike!
 
Just received the cylinders and tried out a set of decent .020 over pistons I had on the shelf; a bit more end gap than I'd like but the pistons fit nice.

Gave the bores a nice light hone.

Front brake caliper installed, still need to fill & bleed the system. Should have a bit of bend in that hose once the bike is on it's tires.

Both lifter bores are chipped, but they were being run like this for some time with no issues. This is the better of the two.

Dressed up the sharp edges.

This lifter bore is missing a big chunk of the retaining screw side.

Thoroughly washed the bores, cleaned the gasket surfaces, masked & painted with gloss black Rust-O-Leum.

Bada-bing, pistons happily in place. I love my ring compressors, and use them with two old chopper tweek bars to support the pistons. Works a treat. Best use of tweek bars ever!

This lump will be reasonably complete soon...

One intake valve had really bad scalloping from corrosion.

Decent trade for Purple Combat


One intake guide was EXTREMELY sloppy. I've never seen a guide that badly worn.

Decent trade for Purple Combat


Sad, sad, sad, sad valves.

Decent trade for Purple Combat
 
Cleaned up the head, gasket faces and ports, replaced the worn guide, then (later) chased the spark plug holes.

Decent trade for Purple Combat


Selected the 4 best valves from a few dozen donors I had on hand, then lapped them in to the head. MUCH better.

Again, it's not a restoration, so it's not going to look like new.

Decent trade for Purple Combat


Noticeable improvement!
 
Head installed and torqued down, head steady installed. I used two strips of old t-shirt stuffed in the pushrod tunnels to hold them in place, then pulled them out before installing the headbolts and beginning the torquing sequence. Works every time.

Coils installed.

Carbs overhauled, air filters on, fuel lines started...

Decent trade for Purple Combat


The end of another long, hot day.

Just saw next weeks weather forecast for Laredo, that is brutal. Hope your shop is air conditioned.

Not air conditioned, but I have a 36" Port-A-Cool shop fan, and take breaks every 2 hours. I drink almost a gallon of iced Green Tea every day and STILL lose 10-15 pounds between June and September.
 
Fabricating a bushing to adapt a leftover Tarozzi rearset pedal to an "off brand" folding footpeg for the rear brake. First knock off the unnecessary shoulder...

Decent trade for Purple Combat


Next, turn down the outside diameter a bit longer than needed, then bore the I.D. to suit the footpeg thru-bolt, then use the parting tool to slice the part off the leftover stock. Less than 1 hour including setting up the lathe, rounding up all the tools and bits, turning down the bushing, and cleaning up the mess.

Decent trade for Purple Combat


Still waiting on a left side Z-Plate so I can mount it all up, but I did round up a brake cable, yoke, and trunnions, plus a bolt-up cable abutment for the pedal end. All leftovers from previous projects, kinda "free".

Now for the fun part: WIRING!

Decent trade for Purple Combat


I did some rehab work on the harness and cleaned it all up.
 
Fabricated a bracket to mount a good used keyswitch, wiring all done.

Decent trade for Purple Combat


Recalled seeing something similar, so I chopped off the rotted/torn part of the old headers "just to have a look". Useable, complete, solid headers on the way already; they'll probably get spray painted, as they have lots worn-off chrome. I have an almost-new pair of replica Decibell mufflers I'm going to use.

Just some progress pix in the sunlight for the heck of it. Timing & points covers on the way. Good Roadster seat (missing tabs) on the way also.

Decent trade for Purple Combat


Left Z-plate on the way, rear brake pedal & hardware, and left footpeg standing by.

Decent trade for Purple Combat


Not too shabby...
 
I was just updating my master spreadsheet with up-to-date info on expenses and parts ordered, etc. When I got to the serial number column, I realized this scruffy son-of-a-gun is only 28 serial numbers apart from my black Dunstallized Combat. What a coincidence.

ahh yes, restoring the bike is have the fun, the other 90% is riding.
 
Left z-plate arrived yesterday evening, I installed it along with all the spacers & hardware. Dug thru the bins and came up with all the bits to abut & actuate the cable pull, setup the brake pedal, and it's all done.

Decent trade for Purple Combat


Recived the seat yesterday, and the pipes this morning. Installed those, the rear hub cush rubbers, and a pair of almost new replica Dunstall Decibel mufflers. Now waiting on the timing cover, OPRV & points cover in order to finally start up the bike...

Decent trade for Purple Combat
 
Got in the timing cover & points cover this afternoon. Can you spot the missing part? Bike can't be started till it gets here.

Decent trade for Purple Combat


I need a spacer to hold the small battery in place, or a different strap arrangement...
