Nearly there with the RD

Well the end is in sight now, I am waiting on some foot peg rubbers to come tomorrow and that should be it. I got a permit for a week today so I took it for a short test ride and it all seems to do what it is meant to. i am going to take it for a ride tomorrow out to Tyabb to make sure no parts fall off 🙂

It is booked in at the bike shop in Warragul on Wednesday for the Roadworthy and then i will book it in for the registration inspection. Oh and the brakes are great for a drum setup.

Spewing Dragon

I ran in to a bit of a problem, when I took the bike for its first quick run I had oil spewing out of the dragons exhausts, I actually drained out nearly 500ml from the mufflers. It took me a bit of thinking bt I narroed it down to the auto lube pump having corrosion on the cable, so a quick spray of mechanic man in a can (aka WD40) and everything was flowing freely except the oil, this was now limted and didnt flow freely out the exhaust…

Lots of news on the RD

I haven’t posted for a while and have been doing bits and pieces to the RD. Most of the stuff has been the fiddly things I didn’t want to do, but the things I had to do to pass the Roadworthy certificate test.

Replace handlebars I used cut down AG bike bars they suit my more erect (read stuffed back) riding posture, it also has an instrument cluster protection bar that will make a great mount for the digital camera when I go on rides.

Sticky throttle- rubbed down the handlebars as they had some old paint on them that was causing problems, and take the burr of the end from the shortening I had done. Lubed up all the cables with WD40 and now I have a throttle that makes a decided thud as the slides in the carby close, nice and quick.

Replace clutch lever as the old one had been broken in the crash

Replace clutch cable as the old one is stretched

I had the back wheel straightened and a new tube fitted, tire is in RWC

Welded up the headlight shell then rewired the bike in to the back of the shell, up to this point I had just been working out the wiring and had it hooked up temporarily.

I had to rewire most of the cables running to the headlight shell as they had been ripped out during the crash. This was the first hurdle to get it running as we had no ignition as the wires had been ripped out so no spark, we ended up hot wiring the bike to start with.

Fitted the two remaining indicators to the front and am looking around for some chrome indicators, round ones that will suit the bike, this way I have pairs front to rear.

Stripped out the axles and brake pivot points (drum brakes front and rear) and lubricated, the brakes actually release now when you let them go and the wheels turn with a light push instead of busting a spleen trying to push it around with dry axles and brakes locked on.

Had the seat re trimmed in black vinyl with high frequency welded seams, it looks almost factory.

Swapped some rectangular mirrors I had been given by Mick for a pair of round ones that suited the bike better.

Replaced the fuel lines.

Cleaned some over spray off the tank, i used WD40 again, stripped the over spray off but didn’t damage the original paint.

Replaced the plugs.

Replaced battery, this was a no brainer a 30 year old battery left unmaintained, I knew this would need replacing and had one on order before I picked up the bike.

Removed muffler baffle tubes to clean them but they look like they were replaced yesterday.

There was a light on the instruments that came on with the brake lights, I disconnected it as I didn’t want it flashing on and off in winding roads at night especially as it was RED what the hell was that designer thinking, red is bad and how is putting the brakes on bad…

Brought an old style helmet on eBay and got some riding goggles with 3 different colour lenses as well.

Well that is about it for the list of things that have kept me busy, with no undercover area to work in I just work in among the rain and at this stage am looking good to have it on the road for Christmas. Then it is time to start getting her ready to take from Melbourne to Perth Australia one of the longest runs in the world, coast to coast it is about 3600 km’s or about 2240 miles.

This is my first long distance trip so any suggestions from readers is most welcome, just leave it in comments. I plan to do about 500km a day or 5 hours riding but that is just a plan, when I get the time I will put the list of items I am taking with me.

Finally Running

Well I got her to run and finally got around to making a little movie 🙂

Here she is running from cold with half choke which I have to cut straight away as she wanted to stall on choke. At the moment I am running a a heavy 2 stoke mix of about 20-1 in the tank plus what the oiler is throwing in from the autolube system so it is pretty smokey.

It is slowly starting to take shape with only a few things left to do then clean and polish over winter to get it ready to register in november

Theres fire in the dragon

I finally got my head around timing a stroke (The RD250 is 2mm BTDC) and then charged the battery, I didn’t have fuel lines hooked up so I pulled the air cleaner out and gave it a squirt of 20-1 2 stroke mix straight in to the air box, I used the 20-1 ratio as I wanted to make sure that those bearings got a good drink of oil after 30 years.

The first kick wielded nothing, however on the second kick she fired and ran for about 5 seconds, I was wrapped that I got it to fire..

I mucked around a bit and Mick and I sorted out the fuel lines and got some fuel in to the tank, but the left carby wouldn’t take fuel so after dinner I pulled out the carby and dropped off the float bowl with Mick, It was FULL of OIL…..

Hmm maybe somewhere along the track someone hooked up the oil line for the auto lube to the carby, I guess I will never know, I will soak the carby in fuel for a day or two to clear the oil out of the galleries then see what happens…

Here’s a pic of the offending carby, found the pic over at

She has a new home

I went down to Brad’s today just to dig it out of the shed, all went well all though someone has ratted the wiring a bit in the back of the headlight. Another job to add to the list of things to do. At least the damage doesn’t appear anywhere else in the main looms and all the wire is nice and pliable and hasn’t dried and cracked.

Here are a few pics of today’s adventures….

Pretty in pink

I have had my first lesson in resto and I don’t even have the bike yet..I am pretty anal and the bike has a small dent in the front right of the tank, I was going to fix it up but have had three people tell me that as the paint is original and the dent is small I should leave it,so decision made and lesson learnt.. Always ask at least 3 people in to resto of cars bikes etc before I make a change to her..

So no she wont be changing her colors and will have her original bronze paint job left untouched.

How to ‘aquire’ a project bike

It is an interesting tale as to how one comes across a project bike, I wasn’t looking for one I was actually photographing sheds (garages/workshops) for a photo project I am working on. While in the shed the photo you see in the sidebar of this blog is the sight that greeted me about 4pm on the 20th of February 2007.

It was the shed of a friend of mine TL (tyabblemons) and when I saw it the conversation went something like this

ME: Hey TL !

TL: Yeah ?

ME: What size bike is this under here ?

TL: Ummm I think it is a two fifty…

ME: Oh yeah, here it is it says two fifty on the side cover,its a Yamaha.

TL: Yeah a Yamaha

ME: Where did you get it ?

TL: I inherited it.

ME: Do you ride much ?

TL: No I’ve never actually ridden that one.

ME: Well if you ever decide to sell it let me know, I might be interested.

TL: If you want it you can have it….

ME: Okay, Ummm… I wonder if we can fit it on the trailer this time.. HEY MICK… can we fit this bike on trailer with the fish tank ?

(ED. Paraphrased due to memory leak)

We didn’t get it on the trailer but I did get my brother sprocket2cog (S2C) to check it out and he said it looked like a Yamaha RD 250,Mick disagreed as he thought they had squarer tanks, and a sportier look rather then the cafe racer look, as it was when I got home and did the internet research thing it turned out S2C was right it is a Yamaha 1974 RD. Have a look at this site for some photos of a few 74 RD’s. ( a wiki on motorcycles. )

I got to speaking to Mick (from my cartoon strip ) about the history of the bike and the story goes like something like this…

I think…

  1. Bike is brought brand new in 1974 by a gas engineer with love of motor vehicles.
  2. Bike is garaged sometime pre 1979 due to health of owner.
  3. The owner never rides again.
  4. Owners son inherits the bike.
  5. The bike is garaged again by son after a quick attempt to start it with no sucess.
  6. I buy bike of son (tyabblemons.)
  • Originally manufactured and assumed brought circa 1974
  • Garaged pre May 13 1979 (this is when the rego ran out)
  • Assuming 12 month registration periods we can say first licensed May 1974
  • Ridden at most 13 May 1974 to 13 May 1979 5 years
  • I found it 20 Feb 2007

So that means with a quick calculation or to that the bike is 32 years and 9 months old, and outof that time it has been unridden undercover for at least 10148 days or 27 years, 9 months, 10 days. That means at least 85% of its life since it was manufactured has been spent under cover and unridden. So I am wrapped with it,and hope to have it all fixed up and registered by Christmas. So anyone that buys me gifts may I be so forward as to ask for bike bits to restore my bike 🙂 thats if you want to give me a meaningful gift..

This is what the NOLAN “Jet N30 Flashback Plus in flat white” looks like

and a page with things I want or need to do to the bike before it hits the road

All I can say to tyabblemons is “Thank you very much.” It has really gone to a good home and once running will be my daily ride…


Its all happening

Well a quick phone call of about 30secs tonight I arranged the pick up of the ‘LIL Dragon” for tommorow afternoon. I will head up to tyabblemons with Mick tommorow afternoon with the camera.

So expect a full photo diary to accompany this blog from the moment I first saw the bike to the moment I first ride it away from the registration office.. you can see a few pics allready on my photo blog at
