And before I go reassembling the carb, which is the best (correct) throttle slide to use on a P208 with a 24/24 oil injection carb? I know I have these two carbs for sure, but I might have another shape as well?

The #4 slide on the right side has the groove in it, the one on the left has no groove.
Few day old post but, that slide groove is a controlled air leak, leans out mixture in that throttle position range. Raw air is allowed to come in through a different passage, oblong opening on the top of carburetor. On my Stella I went to a flat slide as I'd rather be a little rich than lean. Not to mention I had changed every jet and atomizer anyway. Tuning tool without having to create another atomizer.

No much of an update, but something is better than nothing.

I received a new aluminum plate in the mail for the scooter. I have no idea where the old one went. When I bought the scooter there were four holes drilled for it, but the plate was missing.

Maybe I'll have more updates in another 6 months? At this rate I should be finish sometime in the 25th century...

I did a little bit of switching things up under the floorboards and with the exhaust...

Originally (on page 2) i had a stainless reinforcement plate under the centerstand and a Sito+ exhaust. But that was back when i still had the 200cc engine in the Allstate (there's now a 60mm crank, so a 208cc). I ended up finding my old stainless JL Right hand pipe on my shelf and decided to use it on this project. There were a few snafus though. For one, the JL that that was on my shelf had been modified to be upswept quite a bit, so there's no way that the cowl would fit unless i hacked away at it (the cowl). The other issue was that the centerstand was fouling out against the expansion chamber portion of the pipe...and so was the centerstand return spring...and so was one of the centerstand feet. I ended up buying a fancy looking stainless MRP centerstand reinforcement relocation plate. It made it much easier to package EVERYTHING under there! It still took quite a few hours of cutting and pasting (grinding and welding) the P series centerstand tabs to be in the exact place where i wanted them (because i'm using a P series centerstand). I ended up using a SIP exhaust spring hanger to relocate the centerstand spring so that it doesn't rub against anything. All that fitting took hours and hours and hours to get just right.

hours spent tack welding and then grinding off tack welds before i could find the sweet spot to fit P series centerstand brackets.

The JL Right got some loving as well. SIP sells a weld on O-ring manifold thingy in a stainless version. I ended up taking it over to my friend's house so that he could weld it up with his TIG. I wasn't about to attempt to weld it with my spool gun!


the original piece that slips on over the cylinder exhaust stub got cut off.


the stainless SIP piece that gets welded into place. There's a groove for an O ring, so no exhaust spooge for me!


i lucked out that the SIP piece fit perfectly over my JL.


I had to buy a new silencer (end can) for the pipe. The old one had been cut and turned so it wouldn't fit this scooter.


made an exhaust hanger bracket out of a piece of 3/16" wall square tube 316 stainless alloy. Stainless can be just about impossible to drill unless you have expensive drill bits!

How the JL pipe and centerstand fit (more like didn't fit) when i first mocked everything up.

I'm diggin' it!

I cheat and just use mild steel for my fabrication. I fabbed up my own centerstand relocation plate for my GL, which was a lot of work, but also good welding practice.

Do you know if SIP make that exhaust flange in mild steel, or just stainless?

Yes, they make in both a mild and stainless. You could also just buy the stainless flange and weld it to a mild steel exhaust with a standard welding wire. That would be very simple to do, plus you would still get the benefit of having the upper portion of your exhaust not rusting.

Since i'm converting over to an "oiler" engine, i need to do something about a choke cable. The original location won't work for me because the oil tank reservoir is directly in the way of the back side of the choke pull bracket. After reading multiple postings on the web i decided to go my own route. I used a spot weld cutter to drill out the spot welds in the bracket. I'm not a fan of JB weld, but my plan is to JB Weld the choke bracket in the standard lower location (same place as all the autolube P series). I mixed up a test sample of JB on a couple metal coupons that i stuck together. I'll let it cure up (in this cold weather) for a few days and then see how difficult they are to pry apart. If it's difficult to do, then great. If not, then i'll plan B it.








The premix Allstate bracket is on the top. The P series autolube bracket is on the bottom. Notice the difference angles of the flat backer piece that's welded (or maybe it's brazed) to the tube.

FYI, this is the original location of the choke pull on an autolube P series.

I started on the choke bracket relocation today...until i realized i had no rattle can primer in my shop. So everything is on hold until then. But here are a few pics of what got done.


i put some blue tape on the frame and marked with a pencil where i wanted to put the hole.




That's a 2" diameter stainless steel washer that i bent to match the contour of the frame.






i used a grinder to roughen up the washer. It will make the JB weld adhere much better...in theory.


clamping the bracket to the washer


getting ready to weld the two together...






and with the bracket installed in the frame, this is about how much of the nubbin will protrude from the frame.


I also used a grinder to roughen up the inside of the frame for the JB weld to stick.

And this is more or less what Chris would have to do if he wanted to install a factory oil tank reservoir in his GS. It's definitely not plug and play, but i think it's well within any shade tree mechanic. It isn't difficult, especially when you can look as someone else's pictures. Hopefully the JB Weld will adhere strong enough! I should know later this week...

I prepainted the backside of the choke bracket a few days ago with rustoleum rattle can primer and off the shelf blue paint that somewhat matched the bike of the scooter. No, i didn't spray any of the areas where i slathered on the epoxy. The paint was set up enough this morning so i mixed up a small batch of epoxy. It was about 32 degrees in the shop, so i used a heat gun to warm up the vespa frame and choke bracket. I then smeared the ol JB onto both surfaces, and the pushed the two together until the epoxy oozed out the sides of the washer. I used a really long machine screw and some spacers to very lightly clamp the two together. We'll just have to wait a few days to see if this will work or not.




i smeared the epoxy with my gloved finger in order to smoother it out a bit.


various washers and a spacer tube that is holding the bracket in place


A heat lamp to help the epoxy set up. with a high temperature of 48 degrees and a low of 28, the heat will help the epoxy cure quite a bit quicker.

I think it will hold. Perfect use for JB weld. Beautiful scoot!

Agreed on the beauty.
Something about that era in blue.

If Jb cracks/fails - you could try adding a mesh metal screen around the perimeter - to create sort of a composite. Seems like you already have a lot of surface area on the flat - so suspect it won't be needed. Nice solution to avoid ruining paint...

A little touched up paint that really doesn't match and i'm calling the choke portion of this project done. I think the JB Weld will hold just fine over the long haul. Now i need to turn my attention back to making the front VBA fender fit the disc brake.


up close the paint isn't even close. But stand back 6' and it isn't even noticeable.
