My New Project

  • Thread starter Thread starter Grant
  • Start date Start date
My non cooler 3C has the original TT100's on it, bike only has 2k original miles on it, they are in perfect condition as the were stored in a perfect environment, they are coming off soon but the few rides I had on them they worked great, I'm still not sure what the replacement will be but new TT100's are on the list.
 
Stripped the wheels and forks/yokes off the donor bike and then removed bearings etc so they are ready for blasting and paint.
Found a couple of broken bolts on the rear wheel that will have to have nuts welded on in order to safely remove them prior to painting.
Ordered new wheel and steering head bearings an new tyres/tubes.
Hopefully the project will soon be a rolling chassis.

Have you checked those thin web wheels for straightness? (or roundness - you know what I mean). They're soft as butter and are easily bent. Hitting a pothole in the road can be enough to knock them out of shape, so it's worth putting a dial gauge on them to check for run-out - both axially and radially. The flip side of that is they're easy to straighten.

What sizes are they? I was surprised to see the drummer triple magazine test that was posted had 4.10 front and rear, it was no wonder they raved about how well it steered. TT100s were always a good tyre, they even had R compound in the early ?80s that I used on the front for my few races in formula european. Robbie Olsen, who worked for the Dunlop importer, used to race on the vivified Japanese K81s just to prove everyone wrong, won virtually everything. There are much more modern constructions and compounds for sure now but many people don?t need them as they don?t ride like they used to anyway.
 
Rear would have been 4.25/85-18, they're still/again available, at least my tyre dealer stocks them.

Quite happy with the modern version of Dunlops K70, very soft with awesome wet grip, but wears quickly.  Matchy with a tad over 30hp wore the rear bald in less than 4000km.  The excellent performance more than makes up for the quick wear imho.  Would expect their other classic tyres to be similar.

  Piet are you saying my early 3C came from the factory with a 4.25/85-18 rear tire?
 
I'm pretty sure they were 4.10 front and rear on the first wire wheel bikes. The 4.25 size upset the handling a little bit if you changed to that size according to reports at the time inducing a weave, if I remember correctly.
The 4.10 looks very skinny though these days.

Yep, all 1200s had laid down shocks.
The upright mounts were still there (they only disappeared around the series 2 revision) but the shorty grabrail uses that mount.
If you want to you can still mount the shocks upright, but why would you?

Why would I put a carpet on the workmate? The wood is soft enough.

Pic of mine its number1005 its all original except for the wheels, seat cover and some rechroming.  Have you checked the number with slaters theres a real chance yours was in the same batch as mine... ? 
Cheers steve

Can you recommend anyone in the UK who will remove a couple of dings  ?
my original thin web wheels had taken a kerb in their stride in the 80's they are usable as they are, but I would prefer to get them back on the bike looking right
Thanks

It's worth a phone call or email..was the bike complete ?
  my understanding from a notes I made is that slaters 1st batch was a run from 1005 to around 1024 and got 17 bikes, where a mix of ts1200 and mirage's, all the same colour
theres a really good chance it was one of that batch and a small chance it was a mirage... but it would have the 4c cam, horns on the frame jota bars and exhaust etc..
To be honest mines been parked up for years, I keep thinking I should part with it but I can't... I've had it over 20 years and the guy I bought it from had not ridden it since the early 80s it's done 21k in its first 5 years..the odd time I've opened it up (getting a full turn on the throttle is an art)... it goes like stink ! I don't know if the jotas are much quicker but its nice combo of easy pulling power low in the revs but it rockets up to 10k revs if you let it..way past the red line.. what a bike
 
It definitely wasn't a Mirage.
Even though it was a wreck it had A11 cams etc on it.
The first 1200s had the decals instead of badges on the tank, shaved primary cover, Ceriani forks and yokes and so on.
The very first green Mirage I saw in the press was the Slater test demo bike and it already had Marzocchi forks, tank badges etc so I would not think (based on this) that 007 was a green Slater Mirage.
But you never know!

Yes yours sounds like its a ts1200 but I don't quite follow the green mirage.. they came 6 months later.. the first batch of mirage's where blue.
 
I have never seen or even heard before you said it that there was a batch of blue Mirages.
The TS Mirage came much later with the silver with red stripes and handlebar fairing.
Before that they were just the 1200T.
