Tamiya 1:6 Yamaha 1100 Special "The Rebuild"

Super cool!!!

I used to own that bike. It looks real

Simply superb work. Mind bogglingly good.

And a top view showing the carburettors

And the headlight. I haven't added the lamp yet but you can see the headlight tilt adjuster bolt/bracket set up just below the headlight. The wiring sticking up are for the handlebar switches and the accelerator cable

Chrome exhausts. I decided in Chrome instead of gloss black as I wanted to make the black silver theme a bit more prominent 

Close up of the hooters and the instrument cluster

Close up of the front end

And a view from the other side

So made a bit more progress on the bike

Next will be to add rear shocks and the swing arm

Carburettors added now and there are even more pipes to connect later on in the build. It's starting to get entertaining and a little bit fiddly now

Amazing work, very impressive.

WOW, super work.

And where did you get all the teeny acorn nuts and bolt heads?

Suppliers of micro hardware include

One word of caution - because of the micro nature of these items - they are real nuts and bolts and not just heads - these parts are quite pricey but the end result is quite realistic 

Good grief!  Are you kidding???  That's just nuts!  I can't wait to see more.

Just outstanding.  Thanks for posting the pics!

Below you can see near the steering head the wiring from the coils, with connectors heading into the harness and ending in the CDI module on the rear fender 

I tried as much as possible to use the correct colour wires and I this case these are the right colours for these components

You will notice that all electrical components are wired as in the real bike and there are quite a few loose ends still to tie up. The carburettors are next including the complex fuel lines from vacumn advance, fuel taps and the carburettors themselves
Still gotta add spark plugs and connect them us, as well as engine and gearbox breathers

Next I put the engine in the frame, connected the wiring where appropriate and am getting ready to add the carburettors and the fuel piping

This is the front of the engine. The cam chain tensioner unit is in the middle and was a bit fiddly to get assembled but looks like a reasonably replica of the real thing. Bear in mind that none of thsee parts are actually glued together the bolts, hold it all together just like the real engine. Every single bolt has been replicated and there are two different size bolts that keep the crankcase halves together, this detail is also replicated 

This is a view of the engine from the other side. The pipe sticking up between intakes 1 and 2 is for the vacuum advance and links to a complex set of pipes that go from the vacuum advance unit linking the carbs and the fuel tank. The wire running below the engine is the five core ignition cable thank goes directly to the CDI unit mounted on the rear mud guard. I made tiny plastic clips that are used to hold the wires in place. At the rear of the engine you can just see the wires for the starter motor, oil pressure unit plus the reduction box and engine breather pipes. The two breather pipes mount onto the air box. I have put short bits of plastic tubing on to the wiring bits just to keep wires together and out of the way while the engine is being built. 

In this view you can also see the hose clamps mounted on the carb intakes

Engine top end nearing completion. The lower sump and oil filter still need to be added, but that's a bit later in the build

In this view you can see the oil pipe between inlets 3 and 4 note the custom banjo bolts and copper washers

Below is a quick snap of the painted frame with the coils, voltage regulator, lighting unit and emergency stop switch fitted to the frame. have tried to match the colours of the wires as close to the waiting diagram as possible but some compromise is required as I simply can't find 0.4mm red/white or blue/ yellow wire but I think the end result is a reasonable simulation of the real bike. All the electrical connectors are scratch built and everything is bolted or screwed together.

Started painting and assembling parts now that most of the dry run and modifications are finished. Below are the ignition coils. The connectors and shrink wrap are still loose as final position will be determined once the coils are mounted to the frame. The end will feed into the wiring harness. The wiring is matched as close as possible to the wiring diagram of the real bike, but with some compromise. I can't for example find red/white striped wire this small so it's just plain single colours
