    Yeah, it hurted me as well wen I was getting those :p3rry

    Mine seats are roughly repeared by the guys who raced the bike in the past. The older (original) seat is just strenghtened with fiberglas/resin. The newer one probably was broken in half, as they inserted a combination of steel/alloy plate and bolted it into the palstic. Strong enough.

    Thanks a lot Blazz. I have some alloy plates and can rivet it to the broken parts, then add some epoxy glass resin - not the baddest idea I think.

    A mate and I made a carbon one. The guy I sold my 660 to (he was/is in Australia) got the mold. It took a while and a carton of Corona's to lay it up, but it turned out really well. DSC00698.JPG

    That thing just looks great lovebus ! A friend of me offered me to do a seat made of carbon also, but it would cost a lot. I will simply fix my spare-spare-seat like the ones posted from Blazz.

    I did my first ride since june today, just 45km but okay... because I´m not feeling pretty good for months now :( Just noticed our good old sandpit is open again, there were some prohibition signs in the past, but they are gone now :thumb

    And my carbon tank protectors came. I will need to do some adjustments and then clear coat and attach them.

    Just a first try

    Preparing to mount them. I will try to detract the start number stickers and put them on again later.

    I had to cut off a lot of the cf tank protectors, because they didn´t fit perfect. But now they are mounted and I did a ride today :) I noticed with DB Killers (or the meshes in the exhaust caps at the moment) the bike just reaches 150km/h instead of 170 with fully open exhausts. It also needs revs to produce power and has way less bottom end :(

    2 component clear coat and final test of correct fit

    And on they go. I used transparent silicone to mount them.

    My indicators also don´t like the new exhaust caps ...

    Thanks Beta ;)

    FCR 41 is on it´s way to me. The later 660 RRs from 2006 and 2007 had this carb as a standard instead of my 39.

    Made a decible measurement yesterday, the way like police would do it.

    Microphone on a stativ at same height as exhaust cap, 50cm away, 45° angle from the outlet.

    With silencers
    Aeqt (average over time): 93dB
    AFmax (peak over time): 98,6dB

    Without silencers
    Aeqt (average over time): 101,5dB
    AFmax (peak over time): 106,16dB

    And 3 revups without silencers [​IMG]
    Aeqt (average over time): 109dB
    AFmax (peak over time): 119,1dB [​IMG]

    Just took my spare engine to measure the valve timings of the original MSP3 camshaft and my Frauenschuh 1.25R camshaft, here are the results. While the MSP3 was on the original point on the timing sprocket, the 1.25R was a bit twistet to "late". A bit to much I think, but I will change it. I´m doing the measurements because I´m trying to increase bottom end torque, which should work with the Frauenschuh camshaft hopefully.

    A lambda probe is on its way to me. Tomorrow I will bring the exhaust manifold to a welder who will weld in the right sleeve.

    On saturday we will head down to Bardonecchia in italy for a week, our plan is to ride the Chaberton, Monte Jafferau, Cholle Rho and Sommeiller :)

    After setting up the carb by using a lambda probe, the bike is running like hell now :D Took me nearly 2 weeks, always trying to improve the setup when coming home from work. Tried various needles OBDTP, OBDVR, OBDTM, OBEKR ... (and even more clip positions) and main jets from 160 to 185 ....

    I now cam out with a 172 main jet and OBDVR needle on 4th clip with a 52 idle jet and the screw 1 turn out.

    AFR measurements are:

    idle 12.5
    1/8 throttle 14-14.5
    1/4 throttle 13.5
    1/2 throttle 12.5 at low rpm, then 13-13.5
    3/4 throttle 13.8-14
    Full throttle 12.5-13


    I can pull a wheely at 85-90km/h now, just by leaning back and twisting the throttle :D

    Nope, still FCR 39. The local dyno said they need the bike for 2 full days ?! I thought what the hell ?! Sure they just want to test ride the bike... have to find another dyno =/

    my 450 SMR turned dirty came w/a 41mm FCR.... i would think a 39mm would be small for the top end on that bike.....

    As I told him I have 39 and 41 to choose from, Josef Frauenschuh himself told me FCR39 is fine for the bike ... I wouldn´t doubt him

    I hope you drop it and then sell it to me for 1000€. The bike, not the stand.
