Great report Bruno, thank you.

How tall are you Bruno? And how was the comfort of the Seeley riding position compared to the featherbed? I’m just trying to understand how much a Seeley might suit me, especially after that fantastic write up!

Yves, your bike sounds truly fabulous. And it makes me feel very guilty for not getting my 920 progressed more quickly !

But as Bruno said, you have an evil streak, that is one mean thing to do to a friend !!

Nigel, I am 1m78 or about 5'11".
The Seeley felt just fine for me. Yves has installed his rear sets about 2" aft and lower from the swing arm pivot. The attitude of his bike seems to be a tad lower on the rear compared to my Featherbed, but mine is notoriously stiff, a bit like riding astride an elizabethan church bench. As I wrote above, I felt instantly at home on his bike, even if we didn't use a twisty road for this test.
I wouldn't mind building a Maney/Jim Schmidt bike in a Seeley Mk2 if I had the €€€...

+1 ... I just stopped for a bite to eat and read this while I waited. I'm on my pedal bike today- beautiful weather here in Houston (perfect for the MS150 charity bicycle rides first day) I started training too late and was not ready so it's just a short 20 mile ride for me today. I wish I was riding that Seeley though. Lovely write up Jag.

An impressive woman indeed sir. But not only that, all those years she has put up living with an obsessive Norton Nutter as well !

Not only with an Norton Nutter, before I spend 20 years of my life in the Jet Ski racing and she was always on my side, in good and bad days
Here sickness make progresses in the bad way the last years but she keep smiling...She was and still is the most beautyfull girl of the city, so you can imagine how strong she must be now, she as only friends.

Hi Cjandme
Thanks to do that for the MS patients, hope that one day they will find the solution

Yves' rocketship 920cc Seeley in front (obviously!) of my Featherbed Commando.

Hi there,
Here are the good and bad news from my 920 big valves engine:
The good one: the engine is going fast, very fast, the last weeks I was working on the carbs settings and I must be close to the ideal setting but I must go back to the dyno with the gas analizer to be 100 % sure, I put the bell mouths back on the carbs with a Pipercross dual socket airfilter, that act as a air box around the bell mouths, with this the engine bread better.
Here are the setting from the Keihin 35 FCR ON MY ENGINE
Main jet: 145
Main air jet: 200
Pilot jet: 58
Pilot gas screw: 1turn out
Pilot air screw: 1.5 turn out
Jet needel: EMR, clip on notch four from the top.
The bad one: I blow the 0.6mm head gasket, not between the bores, but between the RH bore and the head bolt in front of the spark plug, I dont see any reason for that... or better I see a lot of reason for this: to lean buit I dont think so, I did a lot of plug check and never to lean, to mutch advance I have 27 BTDC , maybe I must go to 26 or 24 ? The compression to high ? or the head gasket him self, the gasket was lazer cut here in Belgium, or the quality of the cooper?
Maybe the 0.6 gasket is to thin, so I put a 0.8mm to lower the compression and I did a road test and I realy don't feel any difference in performance.
Anyway I have to find a solution for the head gasket and the solution is in Germany, the factory name is Elring Klinger, the manufacture all kind of head gasket and they will have the solution, there is always a solution!!
Keep you posted
Yves
 
'Sorry to hear about the head gasket, but, for you at least, that shouldn't be anything more than a quick swap before your morning coffee break. I'm curious as to what is different about the Elring Klinger gasket as compared to the copper that you used earlier?

Hi Nathan
Don't be sorry, this is the normal way when you tune a engine, and I don't believe in miracels, I don't believe that anybody can tune a engine W/O some issues in the begining
About Elring Klinger: take a look at there web site and you will see that the have the knowledge and different type of head gasket, I will call them tomorow
Yves
 
Always love your updates Yves. I and I'm sure others here live vicariously through you with all this work on this fabulous Norton!!!
Keep them coming and Thank You.....
 
Yves, sorry to hear about your head gasket issue. This is stance isn’t it? JS goes as thin as 0.003” so your 0.006” gasket should have been fine.

I guess we’ll never know the root cause for certain.

If you do get the boffins to look at a Elring Klinger to look at this then you could become the global distributor for a new age Norton head gasket !

Hi Nigel,
My gasket is 0.6mm and not 0.006"
Yves
 
Sorry Yves, my error!

That’s what happens when I engage in something before having my morning coffee !!

But that correction only increases the mystery, 0.6mm is plenty thick enough for a copper gasket to function properly...
 
Hi Yves

The 1007cc that Minovation ran blew it's gasket. Traced to the company laser cutting them not using the spec that Steve Maney asked for.

I don't trust any cooper gasket anymore, they are more modern technologies for head gaskets, take a look at Elring please
