    Hi There
    It's spring in Belgium: 14 degrees celcius, yesterday I re-torque the head and tchek everithing, so far so good.
    This afternoon time for the second road test, nearly 20 kms, at the end of the trip I give 5000 RPM in 3 and 4 gear, like I say before, the fun start over 4000 RPM, my God...
    just like you put the post combustion on, and the noise from the Maney exhaust: a symphony for a choir of around 70 horses (I don't know just, no time to make the count)
    Still no vibes, no oil leaks or mecanical noises, oil pressure around the 50 PSI, I plan to do some other kms this WE and change the brake-in oil on monday and go for the Redline oil recomanded by Fast Eddy.
    I have to brush my teeth now, a lot of insects are gluwed on it
    Keep you posted
    Yves

    Seems like a waste of protein ...

    The bike sounds awesome Yves, you are making me feel guilty, and envious, not pushing on faster with my 920...!

    Please keep track of rear mileage til bare or cords showing to give us better idea of how spunky your use is. If lasting 3000 miles then either laying over a lot on throttle or not often using what ya got when upright. This can easy mean a new rear once a month as I found out, so keep spares on hand.

    Well, this morning I saw the result of Yves' hard work and efforts from the last 3 months!
    His engine roars and sounds VERY impressive, especially considering it is only on its first breaking in kilometers!!

    Congratulations my friend, you've done it!!

    Hi There
    Here is what I did this WE:
    Yesterday a did a small run, about 15 kms, and to day I have a date with friends from the Brussels Cafe Racer Club, the date was at 10am and it was cold to go to the place: 0 degress Celcius and I have only summer gloves, my friends have to drop hot water on my hands to take them away from the clip-ons, good to see friends back after a few months, so, I rod 30 kms today, the engine start to live now and still strong, at a moment I start in first gear and when ritching 4000 RPM the back weel was spining and set the bike at 45 degrees, I must say that the road was a bit wet....
    I can not believe that the engine is going so good, normally you can expect some problems after big changes like I did, thanks God no troubles so far...
    I wish to thanks again all the members of Access for all the good advice a receive and hope that I am not boring you with my story
    Keep you posted
    Yves

    Hi Hobot, I start to understand your english, you must know that I dont start very often like on a dragster, I go WOT from second gear on and I use a long gearing: 23 x 36,
    with the 850 I did around 4500 kms with a back tyre (Bridgestone Batalax)

    Yves you are beginning to live what so few ever obtain - more controllable power than is safe to let loose on un tamed un-linked hinging risking skinny tire let go obsolete flying carpet dream machine. HOT DAMIT!

    Beeline thrust is one thing but un-tamed isolastics are so easy overwhelmed with the power ya got on tap blasting into turns. The issue is all is fine as long as hard thrust accelerating tension can be sustained but at some point must ease off and that's when the load let off lets iso's go nutzo.

    Realize real turning only begins after 45' leans other wise just slight extra side force of full blast opens nil turn stresses to tame.

    I highly recommend while still stupidly-ignorantly timidly nursing engine, ya let air out front tire till hard to control for that innate sense to bone memory, then air fr back up say 28-ish then lower rear till saying uncle on the effort to control, then lower both to say 18 rr/12 front and mildly zig zag in one lane till sense of front or rear tire wanting to lift off and sense to control the frame whiplash >> before really testing to peak power top out shifts.

    Commando's are more front heavy than moderns so if skilled can out accelerate the wheelie limited elites but must have dragster launch skills not to hook up too much and flip head over heels. Thankgoodbness Commandos usually just spin hesitating thrust joy instead of wheelie and skinny rear helps protect from this as well as burning up clutch plates. Once competent lifting/floating front on smooth non rear spin on shifts regaining cruise speed after sharp brake for blinds will become routine addictive.

    Unless ya can top 10.5 sec 1/4 miles don't feel too smug yet as my P!! did that in early 70's but almost killed me before getting survival wits to feather power. Seriously use caution on any leaning like entering a hyw before handy with steering by rear only freedom tire evaporating road orgasms.

    Also good to work up skill to find best rpm to drop clutch on to just smoke rear in place w/o need of brake like dragster do before launches. If brave enough to do this w/o brakes through all gears feet up w/o moving a bike length then can equal hobot P!! in '72 or even better it before ya die.

    A 120 rear feels like heavy boot to run in on ordinary Cod's but should consider on your Commando as still easy to spin but grips more before it does and tends to encourage flat tracker ease of rear steering w/o instant snatch downs.

    “Boring is with your story” ?!?

    That’s the first silly thing I’ve ever heard you say Yves!

    The only thing that will disappoint us all is if you STOP writing about your progress and enjoyment with your bike!

    Hobot, in your last post you seem to have slightly overlooked the fact that Yves' powerhouse 920cc engine is firmly bolted to a Seeley frame in front of a TTI gearbox, suspended on Öhlins shocks and Ceriani forks, its phenomenal grunt tamed only by huge magnesium Fontana drumbrakes..

    Another view, with my Featherbed 850cc racer in the foreground:

    This is yesterday's 'old pirates pack', Yves is center of the picture on the second row, right behind the Continental GT and I am second on his left, with the thumb up and a stupid grin on my face:

    Yves is the only one without a stupid Grin!

    Why does he look unhappy...

    Perhaps he’s just noticed a spot of dirt on his bike...!?!

    His hands were still frozen so we (almost) had to pour hot water on them to separate them from the clip-ons.
    0°celsius when he left his garage with the Norton and probably about 2°celsius and freezing fog when the picture was taken.
