1968 honda S800 coupe garaged since 1972 !!!


 this was a very unexpected find , i was on the m40 going to a at silverstone show last saturday and my wife answered a call on my phone from a gentleman asking if i,d like to buy a honda ! i pulled over at the first sefvice station and called him back. he said he had been looking on the internet and found our group "hondaheritage " got my number and said he was looking for an enthusiast for his friends s800 !!! on the monday i had the pictures and information and a deal was struck !!

the car arrived at 2.30 sunday morning !!!! unloaded and went back to bed

1968 COUPE THE NEW ARRIVAL !
after taking delivery ofthe s800 at 2.30 am this morning finally got to bed at around 4.00am got a few hours sleep then up again to spend the rest of today sorting out what ive got !!
initially the car is quite sound the main points of attention being the drivers door and the tail gate both holed and quite rusty ,both front wings lower 6inches are suspect but apart from that pretty solid ..
the body has rust spots all over but as you can see in one of the pictures ive clean of the dirt off one wing and heavily cut back the paint and rust spots and the metal is solid .
moving on to the numerous boxes of parts i laid it all out and have enough parts to make an engine akk components appear very salvageable !
the engine was stripped in 1972 with the intention of building a fast race / road car but was never started although many parts had been purchased to start the build hence two rather nice cranks and an interesting set of carburettors !!!!

hi
my intentions are to keep it all metal and original
it appears very solid on top with the usual rot in the lower wings
i have a nos tail gate and the drivers door i may replace
the interiour is super ther is a bit of swating and rust on the seams under the carpets but all seems solid
its a 36000 mile one owner car with some interesting history of the owner
engine is completely stripped but allthere and appears sound and usable but maybe a safe bet to rebore and replace pistons & rings etc
bore is standard and very good but standard pistons and rings i would think are unobtainable

You definitely hit the jackpot there, RSC cranks, RSC racing carbs, I bet the cams would be as well, interior looks great even the door seals look good.

Hi,

The race crankshafts you bought seem to be in very good condition. How have they been stored? With store engine oil?

Could you tell us the weight of the race crankshafts (complete with the bearing holders) and the width of the parts that connect 2 crankpin journals?
The width of this part should be around 52mm (this is what I measured years ago on a race crankshaft that was supposed to be a genuine one).

thanks

Just for fun, regarding the S800 race crankshaft, here is some old information I retrieved:

- the genuine race crankshaft would be 6,5 Kg lighter than the standard one
- The width of a part that connects to 2 crankpin journals is 52mm.

- It is possible to estimate the inertia gain we get with a race crankshaft and compute the equivalent mass we would have to remove from the car to get the same acceleration gain. This depends on the gear engaged.
