YZ125G Build
« on: July 07, 2017, 04:19:47 PM »
Well, i am just about to test out my OneDrive Microsoft account.  Had it for years and never really used its features.  Its part of my HotMail account. My Photobucket account has gone mad and is asking for big bucks.. wont be using that again..
So here goes.
I raced the YZ125G back in 1980 as a 16 year old.
Here is a Pic of me on the new old girl...



OK, that works good.. free, reliable and easy.  I just uploaded my pics to my OneDrive account, select the pic, click the embed tag.. it generates the code which you copy.  I then put the code between the tags and bobs your uncle.

Cheers,

OK, now that i am off and racing with images, i will start the story..

Was looking for a decent G on Gumtree and Ebay, but nothing going.  (There is one up currently for 2K on Gumtree). I found one on BikeSales  in South Australia.  She looked a bit dirty and rough, but you could see under all that, that it was pretty original.  I called the owner Lez.  He said it was a one owner bike, still on original tyres and piston rings.  Still has all original plastics including a front number plate which is a bit tatty.
I put in an offer, found a courier and bang.. she is on the way to West Australia..

This is the old girl...



I think the matching frame and engine number is pretty cool too...

Since i have my K racers, i have decided to make this G into an original bike.  As near new as possible. I noticed from the pics i had that the sprocket and levers were not original.  I have already sourced an alloy 48t Yamaha nos sprocket and the notched finger style levers.  I wont be able to get the oem number plate, but DC do an exact replica.  The bars, grips etc. are the originals.. it even has the rubber throttle cover.
The front tyre is the original  Bridgestone M21 that came with the bike back in 1980 and is still like new.  The rear is the original M20, but is too worn to keep on.  I am trying to source a Bridgestone M22 which was almost identical but are discontinued as well.  Might have found one but dear as..

Eastcoastvintagemx.com has two G's up on their site at the moment.  Both originals and one was never used.  Both sold.. one went for $6000 US and the other for 5K. I downloaded all their pics so i could use them to reference my build.  Below is a pic of the 6K one...



I would like to bring my G to a similar standard.  Of course it will never be "New", but Lez reckons my G only saw about 10-15 hours use in the last 37 years.  It was never raced, being a farm bike and still has the original stand fitted...



She also has the original seat cover.  Tank is very yellow, but i have some ideas on removing the bromine and fuel stains which involves UV lamps and chemicals..

This G was in an issue of VMX and is close to the condition i would like mine to get to.  Will take a lot of work. I have just bought 3 issues of VMX mag that have G rebuilds in them, to get some more ideas.

What are you waiting for? You are faster than this. Don't think you are... know you are.

Thanks guys, I will try to do her justice. A lot of planning so far. Pipe off to pipe kings.. Frame and parts of to powder coaters, all metal parts of to zinc coaters, tracking down a Bridgestone m22 for rear, found nos 48t sprocket for rear. Hard part will be to make the tank look white again. Can still order heaps of nos gear from partzilla. This bike will be 99% authentic down to the last nut and bolt. Need to find a kayaba air fork warning decal. Will have to use a DC front plate. Original is on, but degraded. Original sear cover will need the Yamaha logo touching up. Will be interesting to open the engine and look at the condition.

Cheers,

get on to café husky, there is a thread on using a hair bleaching product that whitens tanks like a set of pearly's after the colgate ring of confidence ;D

Thanks husky,
I think I am onto it after some exhausting research.  I did some research and realised it can be fuel and bromine leaching. The trick is to use the hair bleaching products, with oxy stain removal products and a uv lamp. I have procured all 3. Also got a hold of a spare tank to practice on. Hope to see the pearlies in the tank and guards..
Cheers,

Thanks husky and itdog..yep, I will be using the peroxide. I read the trick is to add oxy wash to activate it. I also bought a large uv lamp.
That's amazing that you are the new owner of that great g craignduke. You will have to post up some pics. I don't think I will need much stuff to get my one back to showroom as it's mostly unmolested, but just degraded.
You don't happen to have a front number plate or m20/m22 tyre laying about? What about a close up pic of the kayaba fork leg warning decal... Hell.. Just post some nice pics up of the bike.
Cheers,
Alex
