Yeah I'm definitely on sell the P at this point, but the Primi - maybe it waits for spring. I'm still pondering what would replace it, and the most likely answer that's been on my list for a while is a tuned VBB/Allstate on 8's. Not high horsepower, high strung tuned, but more torquey than the P turned out to be, while still running a stock type carb. I'm going to have to study up on the sub-200 block tuning options, but there's been a ton of project threads with them lately, so there is a lot to read!
I fully support the touring-tuned 8" bike plan! Has always been one of my faves combos. Classic style and a little hill-climbing power. Keep it mild and reliable, but tune it to PULL.

OK folks, what kind of "break in" do I need, if any, for new rings and new hone? I need to get out there and set up the jetting, but I'm not sure if I have to baby it for 50 or 100 miles or something first. Mostly I expect that we're talking about setting the main.

It's not really the first start, but I wanted to share. It sounds so different but is idling strong, fingers crossed that setting up the carb doesn't take much. I've gotten better over the years at visually guessing how much slide to use and guessing jetting that will get it going.

Just don't hold it open for too long and for main jet testing this will be less easy.

The first thing you need to do is get a main jet AC BE combo big enough to splutter at WOT

120mj no splutter
124 runs better no splutter
128 runs well no splutter
Uh oh will I need the 120ac?
132... splutter!

Back to 128, there might be a bit of splutter, it's going to be this one or 126.

The rest of the range is decent, maybe the be3 would be better than be5, but it needs some seat time.

It's funny because my throttle markings for the pwk are so wrong, wot on the little carb is about 5/8 on my marking . It's torquey now, but much more like stock. I think it will be well received.

Well that was easy. AC140 MJ128 BE3 all sound like they are correct. Pilot will be either 55/160 or 52/140 and that's that. Quickest custom jetting anyone ever did.

I'll bet it feels slow. Imagine if it was totally stock.

You know it's OK but you notice the hills a lot more. It reminds me of why I started the tuning adventure Razz emoticon . If I swap BE5 for the BE3, do you think the main jet will move much? I'm guessing I'd go up to 132 with BE3 and work down to be sure. But so long as BE5 feels good on one commute, I may just leave it. Pilot is 55/160 and seems good.

I think this was the right move, it will sell now. I've got 2 people asking me to let them know once it is back on the market, one of whom wants to bring a trailer from Long Beach. That's a motivated buyer. 8)

The BE3 will be better. The main jet won't move enough to move from 128. BE5 will make lower rpm feel heavy, will feel ok until you try the BE3, then you will know it was wrong.

AC140 BE3 MJ128 Pilot 55/160 and I assume you have the stock filter on too. This is all good.

Not sure any buyer will believe it is stock after riding it but sure it will sell quickly now.

By slanted roof port you mean the main transfers? I just use a cut down vernier gauge and measure the angled end that opens first.

Back in the 60's when they designed those slanting transfers they thought they were clever. We now know this is garbage but they work and people really like the 200 as a whole.

If you get a chance see how fast it goes on the freeway. You might be surprised.

Yes, the main transfers. So you are in the portion closest to the bore, to capture the opening instant as closely as possible. I thought that's what I had done, but both times my numbers haven't quite made sense. Oh well, we will tackle that in my next project!

Wait a minute, are you saying the transfers aren't parallel to the top of the bore? I didn't try measuring at different points along each transfer (center, right, left). I just re-read your comment and now I'm wondering.

The BE3 was the right move, it feels good.

John, just noticed that your P200E doesn't have autolube. I like that by the way, but that must be quite unusual for a 1980 P series Vespa in the US?

Yeah the previous owner welded up the sight glass before repainting, and tossed all the autolube parts. I'm not fussed about premixing, so I never cared.

It seems the 24.24 would be a nice addition after driving it. I can rev it out to 55MPH in 3rd but 4th won't get near those engine speeds. More fuel!!! 8) I will recommend it to any buyers, along with a guess at main jet for it (probably 135 or 138). 4th is more like 6000 RPM instead of 7000. But it accelerates nicely.

Is ok but I thought you would be getting more in 4th. Even on the 20/20. Did you put the ignition timing back up from 16 degrees? Stock 23 degrees is probably too much but 21 will be ok.

Dellorto make a 126 main? I thought the only ones they offered in that range were 122-125-128-130? I've been using a 128 in my P200 (set at about between 21 and 22 degrees) and it's a tad rich. No issues for the past 10k miles though.

That plug will drop to 122. CHT will be slower to change on the stock cylinder but should still be up at 300F.

Ok then, I've put in 124 for now. The initial trials showed 124 feeling better than 120, so it's likely 124 or 122 is best. Thanks, will report back.

A few years back I bought some jets from SIP for my 24/24. They sent me some aftermarket brands jets. The ID on the jets were no where close to what was stamped on the top of them. One of the jets on my order was something like a 132 and it had the same ID as my existing 128. I ended up throwing away about $30 worth of jets that I just bought.

Craigslist has said that they are doing this now in an effort to cut back on the fake listings meant to rip people off. I think it is a really good change because there always are people looking to steal our money.

It likes 124 much better, there is no flat spot or dull sound when going WOT now and the temps are still very much under control. Now that I've got the idle mix sorted as well, it feels like a properly jetted bike, not just something that's been made safe.
