"You're gonna need to tone that paint down before then Dave"

Indeed, otherwise Steve and his colleagues might use it as target practice! 

No don't! 

There's a chance the Google Earth satellite might spot it and maybe we can follow along from the other side of the world! 

Well if they couldn't see the thing, they would hear it for sure. 
while we're on about the colour, it no longer has any of that paint on it. Gone !
I can tell you that the original colour was gold. After that , AT 1 yellow, then AT3  metallic blue, then matt black and then road safety greenish yellow.
I found the recesses for the badges and cleared them out. Tomorrow, i'm making some new brackets to repair the tank, frame and exhaust.
Also, i found that the lower engine mount bolt has been replaced by a suspension linkage bolt of some description, that the front mudguard has cracks on the mounts and needs a bit of beating out here and there.
I also have a very useful Clymer manual with porting maps in the back of it.
Reading between the lines it says that the best barrel to port is the CT3. The bottom end power delivery is much better due to the seven ports and reed valve fitment. 
There's a DT MX 175 head there in the spares box but i sat it on the spare barrel and the contact face is different so i don't think i'll be bothering with that.

Right then, firstly  Yamaheha. You confirmed what i had just seen on a library picture about the exhaust.
there is no place for it to "go" on this frame so good spot.
secondly I'm going to start a new thread about this bike as i have plans for it. They are based on the desert racing and light weight .
So the new thread will be " CT1 Desert bike"
It will evolve over time.
Mods will include 
A tuned CT3 barrel piston and reed valve block.
Flat slide carb
Aluminium rims.
12 V electronic ignition.
HE15 axels .
White DT1/HT1 paint job
Badged tank ( Ahem )
Chain tensioner.
It's already minimalist so ,we will see how it goes
I have actually been in a desert . The Simpson Desert in Australia

Dave, I thought you were gonna roll it in glitter.
If you take it to the desert it'll end up looking like a chicken nugget

Sounds like a great project, mate

Chicken nugget,hahahaha 

Indeed.  Here we are on Salisbury Plain.  A 155mm laser guided artillery shell is flying through the sky, fruitlessly searching for a laser designation to lock its seeker head onto.  Nothing.

Now almost at gimbal lock, the seeker head spies a fluorescent green beam, 10 miles away.  Steering fins deploy, changes made to mid course guidance and seeker is grimly keeping itself locked onto the beam.  60 seconds to impact it computes. Quite a long shot, it brings the secondary guidance battery online.

At 10 metres from impact, the seeker head detects a pair of bloodshot eyes, the size of saucers gazing at it in horror from a mud speckled face.  The seeker locks onto what appears to be a council yellow petrol tank and arms the detonator fuse.

At 5 metres its electronic brain develops sentience and in a nano second makes sense of a posed answer its seeker head read from a laptop while it was being assembled by a technician.  Hmm.. Roll it in glitter.  The mind runs through millions of computations of possible contexts.

At 2 metres, seeker now firmly locked into the centre of a chrome fuel tank cap that is focusing all that yellow into a tight beam and sending it skywards...  Ah how do you polish a turd?  Answer you can't.... But you can always roll it in glitter.

The seeker head braces itself for impact at one meter and the mind electronically closes its eye.  Oh well, it's been a nice life and I did solve the puzzle..




Best get something done with the paint 
 

Thanks for the laughs!

Tinkicker ,that my man is the correct answer !!!
