Does that dog have heeler in him? Looks like it.
Not sure, don't have many sleepovers these days.

He mostly lays on our bed and gets pet. We were told he is a Red Heeler mix, thinking maybe a pit as well due to the boxy head. Regardless, he's a great dawg.

Great news! The CBR is 100% complete and road worthy.


No, wait.

It's cocooned behind a wall of junk from various winter projects and other crap. I suppose it will hatch out this spring once I have some PTO saved up to use for wrenching time.

I had a few hours to myself today and thought briefly about taking the carbs and all the associated supplies to my cube at work and finishing them. However, I decided to go play arcade games for 3.5 hours and it was worth it.

Well, here I am, stuck at home. WFH full time now but haven't laid a finger on the ol' hurrycane. The days are getting nicer and thank fully my work is starting to wind down a bit. It's been all over the place and over the weekends too. I managed to clean part of the mess away, so I can at least see my bike now.

Once the weather warms up a bit, I'm gonna spend a day getting my crap all organized again. I plan on completely rearranging it so I can park my SUV in there over the nasty months. Got real tired of scraping windows this past winter.

So, it finally happened.

I finally got time, no, finally made time to put hands to the carbs. A quick refresher, the carbs were cleaned and rebuilt but suffered severe leaks at the fuel T. I replaced those o-rings and then the bowls leaked. With new bowl gaskets in, I decided to just bite the bullet and replace the remaining 33 year old o-rings for the fuel overflow and the mystery silver tubes (vacuum?) while I had the carbs off again. This was all late last summer.

With the kids having quiet time and my wife doing the same, I seized the moment and grabbed the the carbs and needed tools. I've never broken a part a bank of 4 carbs and I have heard horror stories and seen first hand, the frustration this can cause when my buddy rebuilt his CB750 bank. I laid out some cardboard, took a deep breath, found my moment of zen, and got to work.

There is so much linkage, so many tiny springs.

I removed the choke linkage and did my best to keep the two middle carbs in place. I was able to replace the o-rings on the mystery silver tube but the o-rings on the overflow port were still pliable and in relatively good condition. When I replaced the o-rings on the fuel T, I bent one of the tiny throttle assembly springs, so I had to do my best to replace it with one from a set of donor carbs I received. It wasn't much fun.

I got the bank all back together and thought, "That wasn't so bad." Queue suspenseful music... I found a spring that got left over. Dammit.

Eventually, everything was reassembled with no extra parts remaining.

BSH recommended placing the carbs output side down on a sheet of glass and using the level surface when tightening down the mounts. Worked liked a charm!

Now, to put them back on the PVC rack and hook up the test tank to check for leaks. Maybe that will happen next weekend.

Huzzah!

With the kiddos home 24/7, we made some layout changes in the house. So, I had to make room in the garage for some kids stuff; in turn I got to clean up the garage. Now, I have room and most of my shit has been put away. I'll post a pic tomorrow for proof.

There is still a lot of chaos to deal with, under bench, over bench, tool box and etc. Just outside of the frame is a mess of boxes and storage tubs that I need to deal with.

Well, the carbs are pouring gas out of the overflow tubes. So, the overpriced Honda o-rings are on their way, and the float levels have been double checked. Gonna name this bike Leaky.

Oh not with these carbs, apparently. These are fancy pants low profile o-rings, to the tune of $30 for both carbs.

I've started plotting out what I'm going to use for lighting, beyond the idea of full LED. Originally, I planned on using the stock
taillight and assembly but changed my mind. So, here's my plan:

Headlight:
https://www.amazon.com/dp/B07L4BLCNK/?c ... _lig_dp_it

Taillight:
https://www.harborfreight.com/6-in-subm ... tail+light

Signals (maybe not these exact ones):
https://www.ebay.com/itm/2x-Universal-M ... SwLBFc8kxa

Third Brake Light mounted on my top case:
https://www.amazon.com/dp/B01GJGCR9U/?c ... _lig_dp_it

The gauge cluster is a combo unit:
https://www.dimecitycycles.com/chrome-a ... meter.html

But I'll be controlling the back light with this:
https://www.superbrightleds.com/moreinf ... foQAvD_BwE

On my XJ, I used an LED backlit "cafe" gauge and it was so bright at night that I could see the reflection of my eyes on the inside of my helmet shield. Kind unnerving to ride at night with your own eyes staring back at you. This fancy little gizmo should resolve that issue; as long as it doesn't malfunction and start flashing at a hypnotic rate.

All the mounts will need to be fabricated, mostly just bent sheet metal rattle caned black or maybe wrapped in yellow/black safety tape.

The seat will be upholstered in some sort of awning or marine grade cloth. The tank will either be the funky sticker bomb plan or maybe custom painted by a my friend who's done some murals around town.

I've got a plan, and it's starting to come together. The Mrs and I worked out a plan where I get an hour or two in the garage on Sundays. My oldest said she wants to start helping as well.

Good news everyone! My o-rings have finally shipped!

Got about 30 min of garage time w/the oldest on Sunday, she helped me remove the seat and the tail light assembly. I gave her the job of removing all nuts and bolts, then putting them back together so they don't get lost. She's excited to assist this weekend. We'll probably tackle the missing chain tensioner on the swing arm and check the chain condition while it's on the stand. Still need to figure out how I'm going to secure the bike for the fork rebuild. My old garage had eyelets in the rafters. I don't think I'll have access to the top of the rafter due to the 2nd floor above the garage.
I'll have to figure something out.

I got the carbs broken down, o-rings replaced, carb bank rebuilt and then installed. I decided to roll the dice and not leak test on the rack. Hopefully the moto-gods will smile upon me. I inspected the front and rear sprockets, both look great (I need to count the teeth though, to make sure they aren't some stunter bullshit). However, when I counted the links for the chain, it came up short, really short. Which explains why the tensioners are both so close, uh, proximal? Then, as an added bonus, I noticed a dent in the tensioner window and that tensioner may be stuck. Which could be why the chain is so short. Fuck it, I'm gonna cut that chain off (it's damn near brand new), hammer out that dent and replace the missing tensioner plate on the right side. This bike has had a hard life previously, and it shows.

Upon revisiting my never ending to-do list, I started stripping out mods and things I can do without, or on the cheap. One of those is the gauge cluster. Instead of dropping almost $200, I'm going to re-porpoise a rugged Android phone running the Ulysses Speedometer App. I'll need to do separate gauges for the tach and temp but those can be added later. Probably the Trail Tech TTO gauges. The app is pretty damn cool, and has tons of features that are worth the money if you spring for the Pro version. Here's what my speedometer will look like:
