    Several days ago, I received a suggestion from the other Scarabeo board that seemed to fit the symptoms of my poorly running Beo perfectly. The suggestion was to check the seal at the top of the newly installed slide and diaphragm. I'm happy to report that was the solution to the problem. The diaphragm was wrinkled at the top and the resulting vacuum leak only allowed the slide to open about 50%. Honorable mention to Rocky, you also had the correct answer.

    Are the clutches normally a bit noisy on these bikes? Mine seems to be.

    if this is a 150 no but by all means when srvicing blow out the clutch bell . Yes by other standards a CVT dry clutch is a crackly noisey piece o crap so if we are comparing to a geared M/C .. yes

    Yes I guess if I wouldve known you were running out of throttle IE wide open is NOT.. you can tell carb is not movin air thru it on stand . but you mustve plastic off and run bike on stand and be watching the slide .. kinda scary for some.. The bike can move on stand ..

It didn't work very well so we replaced them with a large oring, not from Aprilia.
    so effectively the washer is making a restrictor to control water Dwell in the Rad. so Air can pass n cool the water, if it moves to fassst thru Rad Heat will not leave the water . Done this in many old cars with modded engines and cooling systems

    A lot of guys overheated their hot rods when I was a kid by taking out the stat and leaving it out thinking that they would get better cooling in the summer. Had to show them to punch out the element leaving just the restictor in place instead on an old stat which would be a better fit in the housing and less work then machining a washer to take its place. Ah, the good old days!

    Final (hopefully) update on the "new, old" Scarabeo. The scooter is running fine after much effort on the part of my scooter shop and a bunch of cash out of my pocket. Thanks to all for your suggestions for the various problems that arose during the process. This board has been invaluable.
