Scarlet Starting Video Still Processing

Short and sweet update this week, as although I did manage to get video of Scarlet starting again, I didn’t allow enough time for editing and uploading!

Instead, here’s a pic of Scarlet:

I also ordered some parts a replacement fuel tap and a replacement main jet for the one I took form the spare carb. I’m still waiting on the fuel tap.

The replacement main jet arrived though. It looks pretty much the same as this one, only shiner. I’ll get some pictures of the new one when I have other new parts to show off!

I’ll post another update when the video is edited and uploaded if it’s ready before next week’s regular update!


I Lost A Jet, So My Daughter Can’t Rebuild Scarlet’s Carburetor Yet!

Tonight, I asked my daughter to help me rebuild Scarlet’s carburetor, as her mum needed a much-deserved break. My daughter didn’t seem very impressed by the idea.

I thought maybe it would be a good time to compare the original parts with those in the Keyster XL250 carb kit I bought, to show how different they are.


Here’s the kit contents in a bit more detail.

Here’s the needle jet that was in Scarlet’s carburetor, gradually rotated to show the text stamped on it. If you can’t quite see the numbers, it says 77A.

Here’s the needle in the kit – it says D272. It’s also brass and a lot shorter!

The other jets weren’t much better, but at least I can probably use the float valve.

I was about to take a comparative photo of the main jet with the two replacements in the kit until I realised I was missing the original main jet!

My daughter and I had a look near the shed door and on the floor of the shed and found a lot of other parts for the carburetor, but not the missing jet. I put the other parts in a ziplock bag for safekeeping.

“Silly daddy, you can’t expect me to rebuild a carburetor with the wrong main jet!”

So this week was a fail, as is the carburetor until I either find the missing main jet or find time to check if the spare old carb has a main jet I can use.

Maybe I’ll manage to do that in time for next week’s post!


A Stand For Sylvie With A Very Strong Spring

The springs for Sylvie’s centrestand arrived this week, so with all the pieces together I decided to try fitting the stand.


The stand itself needed a little assembly.


The rubber stopper was the first part I fitted.


Next I located the mounting point under the frame.


The mounting pin was the next part unpacked.


I greased the pin before pushing it through. It needed a little encouragement from my trusty rubber mallet.


Next I prepared the springs for mounting. The smaller spring goes inside the main spring.


Despite my best efforts,I couldn’t get the main spring to stretch enough to finish mounting the stand.


Rather than giving up completely, I decided to simply mount only the smaller spring and leave the stand in place for now. I packed everything else into a box until a friend is able to come over and help me mount the main spring later this week.


Hopefully I’ll have a longer update for you next week!

Sylvie Is Seriously Flooded!

I took Sylvie for her first ride after replacing the missing breather hose joint. It was supposed to just be a quick trip to the nearest shopping centre but I’d had some issues with loss of power and stalling on the way there. I returned to find a steadily growing puddle of fuel under the bike!


Closer inspection revealed that the airbox and air filter were completely full of fuel.


The starter motor  was also not turning over and all the lights were also going out when I tried to start the bike. I stopped taking photos and went into damage control mode at this point. I firstly let my partner know I would be a bit later home than expected, then messaged a good friend and fellow rider, who came by with a spare battery from a different model bike, jumper leads and some fuel.

After disconnecting the recently reattached carb breather hose and cranking the starter a few times with full throttle, I was able to limp the bike back home.

While I haven’t had time to look at it since, I will be stripping and rebuilding the carburetor and running the parts through the ultrasonic cleaner at the earliest opportunity!

In other news, the missing springs from the centrestand should be arriving this week, so I’ll hopefully have a longer post (or possibly posts) over the course of the next week!

Sylvie Has A Screw Loose And Her Predecessors Confound Me

This week, I noticed that one of the screws holding on Sylvie’s chain guard on had disappeared.


After lifting it up, I realised it was only being held on by the front bolt!


Fortunately, I found a temporary replacement.


Ready to ride again!

Getting back to the CB250RS’s, I was still trying to figure out what’s going on with Scarlet’s electrical system. I started by having a look at the wiring inside Eric’s headlight.


While enough seems to be connected  to start the bike and get a neutral light, not much else was working last time I ran him.


I checked my slightly modified wiring on Scarlet…

20170205_163809 20170205_163915

I noticed a blue wire that didn’t seem to be plugged in, but it was only one headlight connection that may have come loose when I removed the headlight from the housing.


I plugged it in anyway.



There was a black connector with two sockets that didn’t seem to have anything connected to it., so I had another look at Eric’s wiring. The same connector had nothing plugged in either!

I decided it was time to consult the wiring diagram in the Haynes manual.

This proved surprisingly unhelpful, so I checked my PDF copy of the Honda workshop manual as I remembered seeing a picture of the cable routing in there.

Unfortunately, this just shows the main connection blocks and is in black and white.


As the weather was rather hot, I gave up for the day.

Checking the Honda manual again, I found several wiring diagrams. After consulting the list of Honda Motorcycle Area Codes at, I found the correct one for the Australian version.


This tells me two things:

  1. I need a physical copy of the official Honda shop manual!
  2. I’ll have to spend more time working this one out –  I suspect maybe the fairly amateur wiring changes I made so long ago to get Scarlet working may have failed.

Maybe it’s time to swap Eric’s motor over to Bruiser and swap the wiring loom over to Scarlet…


Scarlet Gets Some Attention At Last


I haven’t posted  any updates on Scarlet in a while for personal reasons. This doesn’t mean I’ve done nothing with her in the last 12 months, however!

Although I haven’t written about it previously, I have replaced the head gasket, adjusted the valve clearances, replaced the regulator/rectifier with a brand new aftermarket one and replaced the clutch friction plates and finally filled her up with fresh oil..

I also took my usual amount of photos as I went along, so these will be added in future posts.

Last weekend I decided to try starting Scarlet again, since she hasn’t been run for over a year.

This of course meant swapping the known working battery back from Eric again.20170129_093745 20170129_093805 20170129_094200

I had to open the cover to Eric’s tool compartment, as the top of it was  blocking the battery.


Scarlet’s looking great but the battery that was in her didn’t seem to be working.


I pulled the battery out to see if it was the problem.

20170129_094434 20170129_094005

This is not a healthy-looking battery!


Swapped out for the one that I know works well enough to start Eric.

20170129_094852 20170129_094951  20170129_095023

Off with the seat to check wiring connections.

20170129_095423 20170129_095434 20170129_095451

Nothing obviously wrong here, so off came the tank to check further along the wiring loom.


Fuel tap to the OFF position


Disconnect the fuel line…


Pop off the left side cover…


And finally remove the tank!


Here’s the aftermarket regulator/rectifier. I’m not sure if it could be the source of the electrical problems.


Also looks like this clip has seen better days!


I reconnected the original reg/rec temporarily to see if there was any improvement. No change to the lack of neutral light, even after several kicks of the starter.


I figured I may as well at least replace the cable clip, so I grabbed the spare one from Bruiser.


It looked a little thirsty, so a squirt of Inox was applied and the residue wiped off with a rage.

20170129_105651 20170129_105736

I gave her a bit more of a polish with Inox and found the summer heat was getting a little too intense, so I put her back together and called it a day.

20170129_110457 20170129_110802 20170129_110823

I’ll need to spend some time checking over the electrical troubleshooting section and wiring diagram again. I have some ideas on where to start, so will test my theories before next week’s update.

Sylvie Awaits A Wheel, A Possum Hitches A Ride and A Roving Staple Gun Is Replaced

This week’s update was going to detail Sylvie’s rear wheel swap.

Unfortunately the wheel has taken longer to arrive than expected, so by Sunday I was looking for something else to do with Sylvie to bring her closer to being road-ready.

I took the cover off Sylvie’s front wheel while cleaning up the carport and was stared at for a moment by a startled possum who was clinging to the front wheel! The possum immediately jumped away, bounced off the cover over the rear of the FZR400 and hid under a sideboard at the back of the carport. I wish I’d been able to get photos or video, as it was incredibly funny to watch!

This possum was found inside the old wall unit in my carport about a week ago, so it may have decided it lives here – here’s a photo of its last appearance


I decided after looking the seat over and finding a piece of thin black rubber foam while cleaning up that maybe the rubber foam could be used to re-cover the seat and simply be waterproofed afterwards.


Unfortunately I wasn’t able to find my staple gun despite hours of searching through cupboards, the garden shed, the bike shed and the chaos that is my study, so nothing more exciting than starting the bike had happened by Monday evening.

Determined to make some progress and have an update tonight – I have a schedule to keep after all – I went off to the local hardware store to buy a replacement staple gun and a staple remover.

Armed with said implements, I removed Sylvie’s seat and set about removing the torn cover.

I then stapled the foam rubber on and cut it to size as I went.

20161219_220704 20161219_224011

Once I was happy with my handiwork, I took it outside to spray with waterproofer

20161219_224348 20161219_224424 20161219_224708

Just in case it rains, I put it back on Sylvie and covered her up.

20161219_231828 20161219_232231

Not bad for an evening’s work!

Hopefully the wheel will arrive soon. I’ll have some other parts on order tomorrow to keep me busy for the next couple of weeks regardless…
