Filtered Air, Luggage Hooks And A Frame Bolt

I finally managed to track down the plastic frames to hold the air filter in, along with the filter itself and the sealing screws I didn’t know were missing in the form of a rather battered airbox from the local bike wrecker.


 I also managed to get hold of a set of mounting screws for the luggage hooks I bought for her a while ago.


I finally got the chance to install them on the Saturday before the gazebo disaster struck.

Firstly, the seat and rear grab handle needed to come off.

Next were the rear “duck tail” fairings

20140823_155852 20140823_155845


I tried installing the luggage hooks first to test out the screws.

20140823_161600 20140823_161553

After realising that the rear fairings weren’t going to go back on over the luggage hooks, I took them off. I already suspected that the air filter frames weren’t getting in the airbox without disassembly, so I started to dismantle the rear sub-frame in order to remove the airbox.

Standard first step is to disconnect the battery.


Next I unbolted the coolant overflow bottle, noting that it was pretty much empty.


After removing the battery, the rear sub-frame needed to be unbolted to get the airbox out.


At this point I noticed something fairly important was already missing!
There should be a hex-drive or “Allen” bolt where that hole is. It seems the previous one had fallen out after I put the airbox in last time.


 I dismantled the rear sub-frame in much the same way as previously shown, pulled out the airbox, put the frames and air filter from the battered one in and put everything back together. Unfortunately I was in too much of a hurry to take photos of the process, as I was losing the light by this stage!

After screwing the luggage hooks in I realised I hadn’t taken many pictures and got a couple of the final result.

20140823_183803 20140823_183815

Then I got a picture of Nix from her “good” side.


After a short week week last week due to shoulder pain putting me out of action for two days, I was keen to get the missing bolt replaced.

On my way home from work on Tuesday, I discovered the left side indicators weren’t working at all! As it was cold, wet and dark, I rode her home extremely carefully and checked the wiring yesterday morning before leaving for work. While I was looking at indicators, I replaced the left front one as I’d been given an advisory to replace it when she had her rego inspection. As I was getting ready for work, I once again forgot to take photos!

A hectic work  schedule prevented me from managing to pick up a replacement frame bolt until today, so I installed it tonight.


Finally, I got a shot of Nix from her “less good” side.


The last few things Nix needs will be adjusting the rear monoshock, replacing the missing “glove compartment” cover along with any missing bolts and finally giving her a good clean and polish!


No Upload Space Left And Disaster Strikes The Gazebo!

Both WordPress and Dropbox ran out of space recently, so updates were on hold for a while. I’ve upgraded my WordPress storage, so updates should be more frequent now!

On Tuesday last week, I had a major setback to my work area.

It was incredibly windy all day and I found my bike gazebo looking very much worse for wear when I returned from work.

2014-08-18 19.43.33

After quite some time cursing and balancing the roof on the pillars (but not screwing them back on) I was able to clear the floor enough to get the bikes out with my trusty loading ramp.

2014-08-18 20.21.20

Fortunately there seems to have been no visible damage to the four Hondas that were under it!

A quick check over of the bikes was in order, so after moving the bikes I proceeded to document it all like any blogger should!

Jack looked no worse for wear. He was moved to the carport with the other registered bikes.

2014-08-18 20.21.43

Eric took it in his stride.

2014-08-18 20.21.58

Scarlet barely noticed, being mostly disassembled to get the carb out!

2014-08-18 20.22.14

 And finally Bruiser got moved into the garden shed.

2014-08-18 20.46.24

 The majority of the spare RS parts got moved under the hexagonal gazebo, followed by Eric and Scarlet, who were then covered with a large tarp.

2014-08-18 20.23.092014-08-18 20.23.28  2014-08-18 20.23.50  2014-08-18 20.23.39

The ex-bike-gazebo is currently precariously balanced awaiting enough time at home on a weekend to dismantle it. The other parts box on the left was moved into the shed, along with Nix’ spare fairings. The green wire shelves remain where they are for now.

2014-08-18 20.22.46

More updates to come over the next week or so, now that I have the upload space issue sorted for a while.

I Know There’s A Carburetor In Here Somewhere – Scarlet Gets Ready To Ride!

So with Scarlet not running well enough to idle last time we saw her, I figured I’d see what sort of condition Bruiser’s carb was in while I waited for the carb kits to arrive.

Obviously, the seat and tank had to come off.

2014-07-31 21.49.322014-07-31 21.50.56

A bit of WD40 to clean things up a bit and get the throttle cables out…

2014-07-31 21.51.392014-07-31 22.01.212014-07-31 22.06.53

Looks a bit rusty…

2014-07-31 21.54.16

A fair bit of grease on top of the choke assembly too…

2014-07-31 22.13.32

The air filter needed to come out to remove the airbox.2014-07-31 22.14.012014-07-31 22.14.10

The battery box is bolted to the airbox, so out comes the battery too!

2014-07-31 22.16.00

More WD40 and elbow grease required here…

2014-07-31 22.30.452014-07-31 22.30.512014-07-31 22.34.10

Now that those are out of the way, I  can get to the carburetor. That’s gotta be it under all that grease and grime, right?

2014-07-31 22.36.45

It looks carburetor-shaped …

2014-07-31 22.38.432014-07-31 22.38.58

After a bit of a cleanup with WD40…

2014-07-31 22.50.45 2014-07-31 22.50.59

2014-07-31 22.51.23 2014-07-31 22.51.32

The same process was repeated on Scarlet.

2014-08-02 11.59.272014-08-02 11.59.352014-08-02 12.00.152014-08-02 13.18.542014-08-02 12.52.32 2014-08-02 12.04.36

Once the battery box was out, I decided to attach the “lockable” tool compartment from bruiser’s battery box to give Scarlet a little more style…

2014-08-02 12.58.52

The choke cable wasn’t held on very securely on Scarlet. This bolt should have been a screw about half the length.

2014-08-02 12.29.07

Scarlet’s carb looked better on the outside, however…

2014-08-02 12.32.05 2014-08-02 12.32.15

2014-08-02 12.32.282014-08-02 12.32.56

Bruiser’s carb was put to soak in degreaser.

2014-07-31 23.02.34

I was working on Rosie’s carb at the same time. It was much cleaner to start with!

2014-07-31 23.02.48

I had a look at the choke cables, as I’d had to remove the choke mounting bracket on Scarlet’s old carb.

2014-08-02 12.38.032014-08-02 12.38.09

After being left to soak overnight, the replacement carb was turned up the other way and soaked again.

2014-08-02 11.39.49

After a thorough scrubbing outside with a toothbrush there was indeed a carburetor under there.

While the inside of the carb was unaffected, I won’t be using this type of degreaser on old alloy again in a hurry, as it seems to have stripped the outer coating along with the grease!

2014-08-02 11.40.00 2014-08-02 11.40.13

2014-08-02 11.40.20 2014-08-02 11.40.26

The throttle seemed to be sticking a bit, so I put some rubber grease inside the throttle assembly at the handlebar end.

2014-08-02 14.52.23

Here’s a video of Scarlet idling after the carb replacement:

Full view of Scarlet from her good side.

2014-08-07 21.23.40

Shortly after taking the previous photo, one of the mirrors came off, so they’ve been replaced with the ones originally from Jack.

2014-08-07 21.55.09 2014-08-07 22.28.58

I finally managed to get the right indicators working by swapping the front one with the spare front one I had from Bruiser, so she’s ready for a rego inspection now!

Since Scarlet is working and Rosie is still playing up. Scarlet’s key gets the Harley Quinn keyring for now.

2014-08-07 22.44.50


I’ll see if I can squeeze in a rego inspection tomorrow before heading off to Melbourne for the weekend – wish me luck!

Rosie’s Carburetor Gets An Overhaul (And I Learn What Not To Do Next Time)

Rosie had been backfiring while decelerating, which is one reason I haven’t ridden her much lately. Since I already had a carburetor kit and diaphragm kit for her, I figured it was time to pull apart the carburetor and prepare it for cleaning.

The first step is of course removing the tank, so the fuel tap went to the off position and I set about removing the fuel line.

2014-07-20 20.52.13 2014-07-20 20.52.56

Next up I needed to remove the tank mounting bolts. These were particularly difficult to remove as the ends have stripped threads – they’ll need to be replaced soon, I think.

2014-07-20 20.53.43 2014-07-20 21.29.09

I forgot to take pictures but there are mounting screws for the radiator cover fairings and another fuel hose I had to disconnect to remove the tank fully.

Finally I got to the carburetor!

2014-07-20 21.41.56

There were several hoses I needed to disconnect.

The overflow hose.

2014-07-20 21.44.24 2014-07-20 21.43.55

Extra hose that passes coolant across to the other side – this might be part of the Thermo-Bob kit…

2014-07-20 21.58.08

Disconnected the choke.

2014-07-20 21.57.40

I left the intake hose attached at the top.

2014-07-20 21.57.56


Fully removed and ready to strip down – front and rear views.

2014-07-20 22.05.592014-07-20 22.06.07

Left and right side views.

2014-07-20 22.06.31  2014-07-20 22.05.53

Disassembly stage one – remove the air cutoff valve assembly

2014-07-20 22.11.03


Stage two – remove the hose fittings

2014-07-20 22.14.28


Sage three – remove the diaphragm cover and slide

2014-07-20 22.15.032014-07-20 22.16.49


Stage five – turn the carburetor upside-down, then remove the float chamber and float assembly

2014-07-20 22.26.49 2014-07-20 22.28.44

Stage six – take out all the little fiddly bits! (aka the throttle stop screw assembly,  pilot mixture screw assembly, main jet, jet holder, needle jet and pilot jet)

2014-07-20 22.44.14


Stage 7 – put it all in a box and half-fill with a cleaning product (I used degreaser overnight, which seemed to work well enough.

2014-07-31 21.28.37

Turn it over and soak the other side (or use a bigger container)

2014-07-31 23.02.42


The freshly-cleaned parts.

2014-08-02 11.42.06

Reassembly step one – make sure you already bought replacement part kits.

2014-07-31 21.30.14

Reassembly stage two – put the throttle stop screw, spring and washer back in

2014-08-02 15.30.00

Reassembly stages three though seven – do everything else above in reverse.
Adjust the float height while you’re at it and forget to take photos of any of it.

2014-08-02 16.33.15

2014-08-02 16.33.45

2014-08-02 16.55.04


I then re-attached the choke and wrestled the carburetor back in. This took at least half an hour and I swore at it repeatedly when I realised that the air box rubber was stuck inside the air intake side of the carburetor and eventually pried the rubber in place with a screwdriver. Re-attached all the hoses, put the tank and seat back on, started the bike, waited for her to settle down after fuel went back into the carburetor and adjusted the idle speed.

I then topped up the radiator fluid that spilled everywhere when I disconnected the hoses from the bottom of the carburetor during initial disassembly and again while trying to figure out where they went.

(Yep, I forgot to take photos of all of that, as I was also replacing a CB250RS carburetor at the same time and was too tired and frustrated to remember by that point! Photos of the CB250RS carby work will be in the next update.)

I polished Rosie for a while, then put the rest of the panels back on, which did a fair bit to improve her looks – that can wait for another instalment, but here’s a teaser image of how she looks now:

2014-08-03 14.57.34

I went for a ride, realised that I had left the idle speed way too high and readjusted it to where it should have been in the first place.


CB250RS Updates

Since I hadn’t posted anything about “the triplets” (Bruiser, Eric, & Scarlet) lately, I figured it was it was time for an update.

I’ve been gradually moving the parts in the best condition across to Scarlet while I wait for the carburetor overhaul kits to arrive.

First up, I swapped the side-stand from Bruiser to Scarlet, as Scarlet’s seemed to be bent.

Scarlet is on the left, Bruiser is on the right.

2014-07-26 10.34.26 2014-07-26 10.34.55

Scarlet’s original side stand is on the left, Bruiser’s original one on the right.2014-07-26 10.44.57

After the swap – Scarlet on the left again, Bruiser is on the right. I’m not entirely convinced that it wasn’t better the way they were originally!

2014-07-26 10.52.462014-07-26 10.52.35

I’ve been concentrating on trying get Eric to start, as I wanted to see if his carburetor was any better than Scarlet’s. I swapped the aftermarket ignition switch with the one that was originally on Scarlet, as the aftermarket one has the wrong connector.

2014-07-26 11.06.06 2014-07-26 11.06.19

The original switch doesn’t sit in quite the right place on the wrong instrument cluster.

2014-07-26 11.10.34

At least it can be connected to all the relevant cables though…

2014-07-26 11.10.56

The neutral light still hadn’t come on with the ignition turned on despite the transmission definitely being in neutral, and there didn’t seem to be any spark when trying to kick-start, so I charged the battery four a couple of days, then put it back in.

2014-07-29 19.54.40

Still no neutral light.

2014-07-29 20.04.02

Off comes the instrument cluster

2014-07-29 20.06.56

I figured I should check the bulbs, even though they had worked when the instrument cluster was on Scarlet.

2014-07-29 20.07.31

Cover off, and the bulbs seemed OK.

2014-07-29 20.08.34

I put the cluster back together and moved on, as this seemed to be a wiring fault and beyond my ability to troubleshoot at the time, as I was quite tired that evening.

I noticed the rear brake lever on Scarlet was looking a bit bent out of shape and wasn’t as shiny as the others.

2014-07-29 21.12.13

Bruiser’s looked a bit rusty but certainly a good deal less bent.

2014-07-29 20.31.50

After removal, Bruiser’s brake pedal looked a lot better than Scarlet’s, although for some reason I don’t seem to have taken a comparison picture.

2014-07-29 20.41.04

Scarlet after the swap.

2014-07-29 20.56.23

Bruiser after the swap.

2014-07-29 20.32.47


As it was getting late, I left it there for the night.

I’ll do the same tonight despite having more updates, as I’m falling asleep and have work in the morning!
