Hi Rob,

You are doing beautiful job there, great see the progress.

Out of interest what method did you use to get the engine back in the frame? I have this to do soon and rather apprehensive of the job.

Cheers

Kevin

Thanks  !

regarding fitting the engine, I placed the engine on the floor (still in the engine frame as supplied by Nurse Julie) carefully laid it over onto the right side and propped with blocks of wood covered in an old towel. Be careful to avoid damaging the points cover or shaft if  the cover is already removed... Then with the rocker breather cover removed carefully lower the frame onto the engine and fit the two bottom mounting spindles. I had the exhaust stubs removed also, but the sump was fitted... Its a 2-man job to ensure you don't damage the paint on the frame.. I also wrapped the frame tubes with old magazines to protect them.. Its then a 2-man job to lift the frame back upright and onto the stand.... that engine is a heavy lump..

Thanks Rob, good to know. Seems to be the favoured method.

Thank you for the feedback, if I understand correctly I should be able to build up my forks ok with the DS stanchions on my K4 (less complex assembly than K0?) But the K2-6 type are susceptible to clonking when bottoming out.

Nothing ever straight forward in the restoration game!

nice work. is that a convertible under the tarp?

Thank you for the kind feedback.

I am badly afflicted by the restoration bug. Its a TR6 under the cover. Another US import from California and genuinely rust free. The rear of the chassis and under panels still had original factory paint on them, protected by a thick layer of spiders webs!

Dash veneer was also destroyed by the sun. I found the wiring had burnt out due to a bodge to a live feed to the light switch. I assume this is what caused the car to be sold.

Every piece of rubber or plastic was rotted due to ozone or temperature. There were a few dents in the bonnet and the boot lid had been drilled to take luggage rack. But every panel is genuine factory and original to the car, rare for any TR6.

So the TR6 was a nice project and worthy present for my wife finishing her degree as a mature student! The car won best TR6 at the TR register midlands concourse in 2013.

Over the years I have restored in order:

1965 MK1 Morris Cooper S. The only car I regret selling. Bought a basket case TR6 in 1980 with cash.
1971 TR6. Sold in 2000 to buy a basket case E Type. Last seen on antiques roadshow being driven by Michael Aspel I have the video.
1965 Triumph Herald. Sold to an American girl living in Stratford on Avon about 1993. Last seen on The Cars the Star being driven by ex chancellor Sir Geoffrey Howe. I have the video.
1970 Triumph Daytona. Sold at auction about 1993 to pay for a bathroom!
1967 Daimler V8 250. Still owned by my mum.
1967 Triumph Bonneville. Sold to a guy from Sussex.
1986 Daimler Sovereign S3. Originally sold new to the MD of Pirelli UK. I sold it to a guy in Walsall.
1974 Triumph Stag. Stolen from my driveway and never recovered.
1971 V12 E Type. Keeper.
1974 Triumph TR6. Still LHD and owned by my better half.
1991 Kawasaki Zephyr, also a keeper.

The CB750 is my first Honda, and I am really enjoying the challenge of it. The complexity of the engine has surprised me given how old the design is. I assume Honda must have started the CB750 K project around 1966/67. The tooling for the cases and as I mentioned the quality of the machining are impressive given the vintage.

So l love a project, and bikes are more manageable now. Still lots to do on the 750 to keep me busy - for now!

Realised at this stage I had mounted the engine to my engine stand the wrong way round, so turned round whilst still manageable. Cylinders and head reassembled with out any dramas. Which pretty much brings me up to date.

New chain tensioner and blade, cylinders, head, cam and rockers  fitted.

So that was where I was.
Since then good progress on all fronts.

 - Frame blasted and powder coated frame, swing arm brackets etc.
 - Wheels stripped. rims re chrome plated, hubs polished and rebuilt with new stainless steel spokes and fitted with new conti tyres.
 - Headlamp shell painted, all missing parts sourced and new halogen unit fitted.
 - Good used original taillight sourced and fitted to re-chromed bracket.

More to follow -

Thanks for the replies. Central wheels built my wheels but their prices for Conti RB2/K112's is not competitive compared to online dealers.

So looking for fitter that will fit tyres, tubes that I supply.

John, if your supplier will do this I would appreciate their contact details.

Cheers,

Kevin

Thank you all for your welcomes and support.

I am going to enjoy this forum.

Hi Menno

Thank you. My painter is going to hand paint the design. I assume if it's silver it is a very light silver, and for white is it flat white or pearlescent?

In your opinion which looks better, white or silver?

Kind regards

Kevin
