3C or not 3C

Not trying to re-write history here Lothar/Bob, the reason for Grants post relates to one particular bike and the history of that particular bike. Regards Pat
 
In one of my 1975 UK Motorcyclist Illustrated magazines, there's a great article by Dave Minton about the 3CE, titled The English Way.    I would like to post a copy of the article, but copyright issues seem to prevent this.  In addition to the exhaust changes, SFC yokes, etc, Dave makes mention of stiffer springs in the front and rear Cerianis.  He made no mention of different pistons or cams in the the bike that he tested.
 
Well, interestingly I have been reliably informed my 3C(still checking to see if it also has an E) was originally blue in colour.
Currently it is orange, and the inside of the sidepanels was a deeper bronzey orange, but none of that guarantees anything after 36 years.

My question is: what shade of blue are we talking about?
Is it a dark navy blue, or a purplish blue, or other shade?

It is going to be RAL 2010 any day now, but it would be interesting to me to learn more about the original colour.
 
Grant , if it's the dark navy blue colour I can point you in the direction of an exact match. Police Metropolitan Blue. When I had my 3C the original blue was under the filler cap seat. I took it to pal who paints classic and he came up with Police colour as the perfect match.
Lovely colour for an old bike,  see pic of my old bike after it was painted.

Your old bike's colour was what I had in my mind's eye. I can recall a row of 3Cs in Lloyds of Hamilton in the mid '70s and that colour stood out. I know the 750 had a lighter metallic blue, but I don't recall any triples in that colour, well not until the first 1200s came out.
 
The 3Cs were available in that colour, in fact one of the press test machines was in the pale metallic blue. My good mate James McBride used to have one.  
Here he is fixing it, something he had to do quite often on that bike!

I was standing next to the cameraman when that shot was taken.
James went off to his tent to get changed in order to sort the loose/trapped bolt from the sprocket carrier that got jammed in the swingarm, and by the time he had returned we had dismantled the wheel, called Gijs Van Dijk and the part was on it's way to the rally site.

That was an attempt by James to keep My SFC 750 he insisted we swap bikes on the back roads in Holland when we got back to the rally carpark the bolt came loose and jammed, his intention was to wipe me out and keep my bike,i still have the bolt :D :D :D :D :D :D
 
When I bought my 3C from slaters in 75 there was a selection of 3C's in various colours but the metallic light blue looked great. I might do my next one in that colour.
 
Some years ago I had an SF2 painted by Noel Jackson (some will know him).  I chose a Ford metallic blue, just because I liked it, and he nearly wet himself because he had ordered a Jota from the factory in pretty much that colour many years ago.  Not sure which year, but it must have been around '78 or '79.
 
So , Is the Jota essentially a 3C Bitza upgraded and built by Slaters initially and then adopted by the factory.
What I'm saying is, is the 3C in fact THE original and untainted Laverda Triple  ;)

Yep, I agree.

And then we have th "3CE Jota" at the bottom of this page on the MV Augusta forum

http://www.mvagusta.net/forum/showthread.php?t=34173&page=2

Looks like quite a few out of place bits.

Ahh, seeing the avatar, this looks like Jotajoe's bike, but from later description certainly does not sound as though it is in original form.

Aha , I've been rumbled ! That was my old Jota. I bought her from a guy in Swindon as she is there

I kept the tank and side panels and exhaust and built a Jota as I have posted on here...The engine from this particular bike is now owned by a forum member here.

Joe ,
Obviously the 3C is the original triple , after all it pre dated the Jota by  5 or 6 years, but the Jota isn't a bitza by any means, it's simply a 3C equipped with some factory endurance race parts and an exhaust developed by the UK importer.  Roger's develoment on the original 3C had been done using factory parts, the factory had already been modifying bikes with these parts for their own racing progamme. What Roger did was to experiment with some exhaust configurations in conjunction with these parts. The parts became available because the factory had been using them with some success for their own activities.
Bob
Here's a nice pic of one of Slaters early wire wheeled 3C racers. The pilot is PK Davies*.
PS All this information has been printed in numerous books over the years, there's no ambiguity about the Jota and its origins...except perhaps on this forum! :D :D :D

Cracking photo Bob....reckon it could well be PK as he wasn't a big guy and had that neat "take no prisoners" riding style  8)

i often wondered if the use of the SFC yokes was to restore the original geometry after cutting and rewelding the top tube.
slater admitted to cutting the top tube on the proddy racers. i've heard others say the change of yokes improved high speed handling.
without any tracks nearby i find i exceed my abilities long before the bikes on public roads so it has never been an issue i've needed to address

one of these days i'll get around to measuring the trail on a 3C with each set of yokes
maybe when i get around to assembling my 3C  ;)

Scott, I think it could well have been, or it might have helped give a bit of clearance for the centre pipe under braking .

Scott,

Can't really see how they could improve high speed handling.  The 750SFC yokes effectively decrease trail, thus letting the bike being able to turn in quicker, should make it quite a bit looser on the straights and in fast sweepers.  Maybe it's the additional 17.83mm wheelbase...... :D

Meanwhile, back at the ranch...

The 3C clocks have come back already from the refurbisher.
Well smart they are too.
Here are before and after shots.
