Good shout on the paint, bit, I'll have a go, if I nee some of that paint I'll be in touch, thanks for the offer.
Just picked the wheels and forks up from Graham

its going to look proper mint tho by the time you've had all this blasting and plating done


I think it will be quite away from that, maybe a bit of 'Patina' may not go a miss     8)





here are some close up's


Still a bit of residual rust, but I'll spray over these just to stop it getting worse.

Like I said it's not perfect, but it's a lot better than it was.

I've just got to get this front brake cable outer welded and re-threaded.   :(

As for the forks, I could not get the top cap's off, so I left them with Fastline, it needed heat and liquid nitrogen to get them to release!!!!!

So time to follow cosworths instructions and drop the forks internally

Wow! It's looking great! I'm very jealous, makes me realise how much work is ahead of me on my build.

More blasting   :D

Just need to get the 50mm spacer to drop the forks and then re-build them.

Maybe try 35mm spacer and drop them a bit in the triples.

I say this to only add caution that the fender not hit the headlight under compression if you have a lowered headlight (which you should). Ditching the headlights bracket and adding some $10 fork mounts for the headlights is the way to go.

So by going 35mm on the spacers then adjust in the triples you came get the 50mm you want but go back to 35mm without fork disassembly.

 I'll do that cosworth. I'll get 2 x 35mm and 2 x 50mm ones done. I'll try the 35 ones first.

I may end up dropping the forks through the top tree as I may want to add some clip ins above the top tree. The only problem I can see is that I may have to remove some material from the top tree to fit the clip ins.

Wheels all built, with all the fittings re-plated.

Tyres fitted, but I'm not sure if the back is a little too big or the front needs to be bigger, I know it I will get a better idea when the forks are built and I can assemble the frame with the wheels in place, but I wonder if I made the wrong choice size wise. :-[

and I think I have found the colour it will eventually be, Tech House Grey.

It's a Fiat colour

I have that tire size. MS90 on the rear of a 250 looks like a superbike tire. I just wish there were Michelin Pilot Power race in that size lol.

same an old 130/90-16 just came off mine. it rode fine. I replaced with a 120/90-16 only cause the tire I wanted did not come in that size. I went with a Bridgestone trailwing.
Funny thing is the 120/90 I put on there is actually a little bigger than the 130/90. Each manufacturer can have variances in how they measure and how each tire expands.

got it rolling, well of sorts.

Forks rebuilt using 15wt oil, 2" spacers and 1" off the spring. Seem a little firm but lets see how it rides before any more fiddling.

still wondering what Bars to use  :-\

Piccie shows Renthal ultra low riders, but I have managed to get the bosses machined off another top yolk, so clip-ons may be possible, but I think it may need some rearsets to complete that look. Rear is set to 300mm E2E. The shocks that came off were 320 E2E.

Existing rear mudguard seems to fit perfectly is moved forward as well which is a bonus   :)

I have asked a local engineer for costs to produce some aluminium mudguards similar to the ones on this triumph, so we will see what he comes back with. I think they are more 'scrambler/tracker' than the standard rear guard.

Oh and that Triumph colour I think looks superb
