    Swapped out the rear tire, cleaned up the wiring and added the horncast, then added in the new CDI and assembled and installed the cleaned tank.

    Sorry to nitpick—the front wheel is on wrong. The deep side should be on the right and the shallow side on the left, with the valve stem coming out to the left. Here's a photo of the left side for reference:

    Everything else looks fantastic!

    Yeah, I figured, but I am too lazy to dismount it again, and I wanted the tread going in the right direction. Not a big deal as I have new wheels and tires coming because these are ratted out, and the "new" tires are 9 years old.

    But I do appreciate your input!

    Following this thread, regret selling my PX200 some years ago.

    Moved out to the countryside and commuting with it on the highway was not a pleasureable experience.

    I didn't know about that BFA306 motor. That is unreal.

    I saw this cutie in the Frankfurt airport yesterday.

    BTW, used your videos to change the brake, transmission, and FD fluids on our R1200GS which is stored in Germany. They were a great help!

    The BFA is not very cheap. A slightly more economical path is using one of the many quality aftermarket new crankcase sets, a cyclinder of a Simioni paraglider motor and one of the optomised cranks. 36 rwhp out of the box with lots of reliability, plenty more to come with a competent tune and pipe.

    Took the scooter for a ride around the neighborhood. Needed to stop and adjust the brakes as there were basically none. It ran great, and the clutch works fine. The shifter is very stiff and difficult to get to move, but I have new cables for everything. The suspension is surprisingly OK, as is the power despite my 260 pounds.

    The headlight, just glows red on the filament on high and low beam. Must be a wiring issue as the bike is charging at 14.2 volts off idle.

    My big issue right now is the fill plug won't come out, no matter what I use. I may have to weld a nut on it to get it off. Anyone have an idea for a fill plug that uses a hex head instead of a slotted head?

    Anyhow, rust is not as bad as I initially thought. Here are a bunch of photos.

    MAP Gas torch, smoking hot, huge screwdriver and a wrench on it, and it finally broke loose.

    Oil looked good, and was full. I changed it anyhow.

    I also cleaned the shifter box.

    Then installed the intake boot and electrical cover on the CDI.

    Took it for a longer spin, 3 miles, and it ran great. The front brake is still very weak, and it still shifts badly, popping out of second, and very stiff.

    Gear change problems

    1. cable adjustment, at least this is cheap to the point of nothing. Unless...
    2. cables require replacement, not very expensive, but can be a pain. But less than...
    3. cruciform needs replacement, bit more of a job. At least not mind numbingly expensive.

    There may be other things that people into Vespas have been made aware of, but I only rode a mate's for a few months.

    We know you are having great fun doing all this.

    Yeah, I am trying to decide if I should just change the cables, which I already have but was saving for the full rebuild, or just adjust and hope for the best for a few months. The Cruciform will get changed this winter.

    Definitely having fun!

    Often the trick with shifting is that the clutch cable is not fully adjusted. There is a lot of travel in the clutch actuator lever that is just getting the play out of the spring. The trick is to use a third hand tool or two vice grips to get it right. If you actuate the lever by hand, you can really only push it by hand to where the play is out of it, you can't really actuate the clutch by hand and if that amount of play isn't already taken out with the clutch cable, it won't fully release.

    The real trick is to use the third hand or two pairs of vice grips to apply enough pressure on the arm and then tighten the barrel adjuster at that spot.

    This link isn't completely clear, but it helps envision the process: http://vespamaintenance.com/body/clcable/index.html

    As far as the oil goes, it will pretty much always look clean because it is only lubricating the clutch and gearbox, it's isolated from the combustion chamber so it's not like on a four stroke where it gets dirty.

    Received while I was in Tucson.

    These should be much safer than my old rusty rims and ancient tires.

    Not going on until I get ready to paint them, and the rest of the bike.

    On a side note, these rims, tires, tubes, nuts and washers are about 3/4 the cost of just the front tire on my motorcycle, or 1/15th the cost of wheels and tires on my R1200GS.

    This makes it much more fun to buy new, even if it adds to my potential losses when I sell. :-)
