    Hi Nigel,
    Thanks for the invitation, but I have two problems: my dear Marina is disabled and I can not leave here alone more as one day, the second problem is: if I go on the track, I have no limits and for sure I will put the Seeley on the ground and maybe hurt my self, you imagine if I broke a leg or so, how can I take care for Marina?
    I will speak with Bruno and try to find a solution.
    I am more intrested in a drag event over 1/4 mile, if you can find one I will be glad to come over
    But we will meet us in Belgium at Chimay or Gedinne or not?
    Thanks
    Yves

    I definitely want to attend Chimay one day. No chance this year though as my ‘bike calendar’ is too full already.

    We all have to balance our bike calendars with our family life. And despite how committed we may sometimes appear to our funny old bikes, family must come first. And that includes Marina, who sounds like and unbelievably tolerant and understanding wife Yves!

    Maybe we can have the Trident Hunters Club meet at Chimay next year?

    Yes Nigel, Marina is a fantastic women, 30 years with Multiple sclerose and she NEVER complain!
    Bruno did a test ride from the 920 Seeley to day, he wil do his test report soon
    I was watching him a long the road, and I was impressed my self to see my own bike on the road
    If some member can keep me posted about drag races in the UK, I will be very tankfull

    Well guys, not sure where to start...
    I did try Yves' 920cc Seeley this afternoon. I started very conservatively because I had never ridden a Seeley and I wanted to get the grasp of the bike as a whole, not just its engine.
    What an incredible job Yves has done with this bike! Even though I am about 10cm taller and 25kg lighter than him, it took me just about 4 seconds to feel completely at home on his Seeley. All the controls are exactly where you expect them to be and everything went completely flawlessly during the 30 minutes or so I was on the bike.
    The bike feels very light, and lower than my Slimline Commando. The clutch action is smooth and easy, a gentle push on the gear lever and of I went...slowly at first, as I didn't know what to expect. Even at 1/3 throttle, the engine feels full and lively, the TTI 5 speed gearbox is an absolute revelation, silky smooth, perfect ratios, I am seriously thinking about selling my left kidney to buy one asap.
    The front 4LS 260mm magnesium Fontana brake is nothing short of incredible, progressive, powerful and immensely precise, much better than most modern disk set ups,the rear 2LS 230mm magnesium Fontana is probably a bit too powerful for this very light motorcycle yet perfectly precise and safe to use. Actually on a couple of'occasions I used only the the rear brake without even touching the front to slowdown Yves' rocket before a roundabout and it was not a problem at all, quite incredible in fact!! The Mk3 Seeley steers precisely, goes exactly where you want it to go at any speed, thanks to Ceriani GP forks and Öhlins rear shocks.
    If it was my bike (dream on, Bruno!) I would probably adjust the rear shocks to be a bit harder considering the brute power delivery of Yves' mighty engine.

    Yes, I know, I know, I haven't said anything about the engine yet.
    Well, it starts on the Alton starter button, idles with the precision of an atomic clock, and is suprisingly vibration free, even at low rpm. At first, I wanted to remain very cautious and kept my right hand below half throttle. In those conditions, the engine feels full and responsive under 4500 rpm, not so different (I naively thought) from my own 828cc PW3.
    But after a couple of minutes, Yves, who was standing by on the side of the road, started to make big gestures telling me to give his 'Big Spender' a real go.

    So I did.

    Should you decide to twist your right wrist on Yves bike, here is what happens: with a otherworldly roar from the Maney exhaust, Yves bike suddenly morphs into Maverick's Tomcat on afterburners being launched from its carrier, the front of the bike starts to feel very light, click, second gear front still feels very light at 7000rpm, click, third gear front still feels very light at 7000rpm, click, fourth gear what 7000rpm already?, click fifth gear oh shit this thing is really moving, time to leave Warp 8 acceleration, Scotty Bruno reporting serious facial grinnage inside space helmet as he flies right by Captain Yves Kirk on the deck. Looking on the rearview mirror for Thor's hammer which, I am sure of it, just kicked me on the backside, I see nothing but an empty stretch of road.
    As I am a lifelong epicurian, I decide to go for it again.
    And again.
    And again.
    After all, Yves has asked me to try his bike out and encouraged me in no uncertain terms to 'test-osterone' it.

    So I did.

    The engine pulls like Saturn V from 2500rpm until Mjölnir (the aforementionned Thor's hammer) hits you squarely in the backside from 4500 to 7000rpm. Vibration free, the engine feels free and open, completely quiet mechanically at all revs, torque and power galore. As I write this report, I am trying very hard to find something wrong to Yves' bike and incredible engine.Yet I just can't find anything less than perfect on his bike.
    His 920cc Seeley is the stuff normal people's dreams are made of.

    After some debriefing and (many) compliments, I said goodbye to my friend Yves after thanking him for the privilege bestowed upon me etc., ...one good kick started my PW3 Featherbed Commando and off I went for a happy ride in the Belgian countryside. Or so I thought.

    Bruno was not happy at all by now.
    Quite pissed off even.
    My mighty 828cc PW3 engine now feels like a mere glorified moped after trying out Yves' spaceship.
    Oh, do I hate Yves now.
    One cannot do to a friend what he did to me this afternoon. It's not fair.

    Just not fair.

    I need a drink. Or a few.

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

    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.

    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 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, 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 !
