Modern Vespa

Oh wow.

This will be a challenge, too. The harness you have isn't wired for the four pole ignition switch on the headlight, it doesn't have indicators, and your switches are a different configuration.

What kind of indicators were you planning to use?

I think the closest one made is this German one. But it's a battery model.

It has the indicators on the headset, and the ignition switch.

The handle bar switches are different, though. It has the add-on turn signal on the left side, and yours has the two square switches.

uh oh. I was planning on using those bar end indicators in the diagram you showed. The loom i got was https://www.sip-scootershop.com/en/product/wiring-loom-sip_86135264

but I do have the orig american turn signals and switches

This is the ignition switch I have.

HJO If you are willing to accept a help-visit to take a look at this challenge, I will bring the best guacamole you have tasted this side of the border, my grandma's recipie.....and I would love to take a peek at your Rally, maybe after the heat wave? its 110 here today

Cali is basically the surface of Mars this week lol

I love Santa Rosa.

That's actually where I bought my Rally. It was some dude who was retired and used to own a vespa shop. But he left it outdoors for like 30 years.

The bar ends should be easy. The wires are right there by the switch.

I'm not sure what "Anti-theft device" means. It could be that key switch. But the keys on those don't even have teeth, so maybe not.

I am actually in Petaluma, but Santa Rosa is next door. We do a monthly ride to an english pub, about 10-20 people.
I feel hopeful, gotta work on the patience part lol

Welp threw in the towel on the electrical and brought the yellow wasp to a great Vespa guy in SF. After I get it back the fun will continue!

Is that Second Chance Scooters?

Yup. Joe is helping me out.

I never met him, but I follow in Instagram, and he does beautiful work.

He works on all these amazing bikes, that are local, but you never ever see.

It's this collector market that I didn't even know existed.

He had an amazing GS that was cream. He does great work and we talked for what seems like two hours about Vespa stuff. It was great and he does all his work from a retro fitted van. It's so organized! He used to be the mechanic at b….M…… but started his own thing. Let me know if you want to come with when I pick it up.

Sure! Let me know!

Today I took out the p200 for a test ride after a cruciform replacement. 26 miles to the skatepark in the woods. It rolled like a champ!

My wife would just *love* that..."Honey, I'm going to do a dangerous thing to get to the place where I'll do a differently dangerous thing." She has no concept of fun sometimes

What's even funnier is her reaction when you break down at said skate park and call her for a ride.

Or, in my case, get myself home but then need a ride to the emergency room. She LOVED that one.

I've learned how to suture and have closed myself up on more than one occasion. It's less painful then "the look".

even that has its limits... Ride safe, everyone (gruesome pic warning)

whats better if I had broken down, there is no cell reception there! thus the 20 lb backpack with tools, cables, votive candles lol

I didn't see a cage for the sacrificial chicken, or do you store her in the glovebox?

that bird is buried under the garage! hey sorry about your knee and that I missed that post, looks like it was rough. I am gonna heed your advice and get some armored riding gear. I rode out in a sweatshirt and jeans and rode back in a t shirt and jeans. I ordered a jacket once but it was too big so I returned it and then let it go, but lately it has been on my mind. thanks for the reminder!

Good man!

Yeah, I've always been diligent about wearing a jacket, but generally only added pants if it was cold, rainy, or I was going to be covering a lot of distance. Now, I wear overpants about 90% of the time. I have some mesh/ventilated ones that can be put on and taken off without even taking off my boots.

It feels a little weird in a dorky kind of way at first, but now I'm just another road-grimed astronaut. After all, the pavement doesn't care what you were riding if you go down.

Well I picked it up from second chance scooters yesterday (sorry I didn't call hjo, was just a quick workday pickup)
The electrical is done and he checked my work and found some mistakes that I missed and would have been bad, as it's my first build I wanted a check (for safety etc). Anyway plenty left to do, more to come!! Yay

Awesome! All the lights work?

yup, I have bar end blinkers but when I ordered form SIP I only put 1 as the quantity so f me! I have one blinker working now but all else works. The lights ar 12v so really bright. Gonna do some trim work today and just put in parts orders

Just need to remember to swap the blinker from one side to the other before you turn and you'll be fine!

Successful first ride around the block! Seatless but I did get to use my right blinker! Put the badges on and I know it's the wrong tail light but I like it while I get the right one. Love it so far!

Hey all been cold and rainy so not much garage/shed time for me..can anyone tell if the woodruff key is in? I see a hint of it in the close up pic. It torqued to 45 ft lbs then I took off the nut to check. The flywheel Feels like its in all the way and key seated but I have been second guessing myself....you have to enlarge the pic and I put an arrow pointing to what I think is the woodruff key

When I'm in doubt, I take the flywheel off and check. I reseat the woodruff key, get some light on it and put my beady little eye right up to it and watch the key slide into the notch. I can't see for shit and I can't do it by feel either. It's still better than guessing.

also, before fitting I check that the woodruff key slides smoothly in the keyway of the flywheel, and if it doesn't cleaning it up with a file till it does. reduces the drama...

Now I wish I had a Time Machine haha !

Hey all, been a while since I worked on the Rally, between rain and cold I don't get in there as much. But the upside is I replaced the woodruff key and it fires right up. Downside is gas is shooting out the exhaust, right from inside it. I read lots of posts about it, so I cleaned and rebuilt the carb, replaced all the gaskets changed the float bowl, and needle (and it seems to move up and down freely )but when I put the carb back on and started it, there was still gas coming out the exhaust....think it could be leftover from before?
The carb is a spaco 26/26 and it seems pretty new. It came with my P200 when I bought it.

I know theres a scenario that may require a rebuild, everything is new hardly been ridden around the block....so I hope it aint that.

That screams bad/incorrect float needle, bad float, or bad float needle seat.

Assuming that the first two are good since you just replaced them, try polishing the needle seat with toothpaste by putting a q-tip or bamboo skewer in a drill and polishing it that way.

You can also confirm that the float is leaking by sticking a paper towel down into the mouth of the carb so it's under the fuel stub (the brass bit sticking into the carb mouth) and letting it sit. If it's leaking, the paper towel will have fuel on it.

Thanks Chandlerman, I will give it a shot.

That was it! I had an extra dellorto 24 so I used that float needle seat and it fit great and resolved the problem.

Now I keep flooding.....no more gas coming out the exhaust....I have a sneaky suspicion that it is because i installed an sip fast flow fuel tap. I may just use the stock one I bought in the first place like the one on my tuned p200 which delivers plenty -o- gas.

Could it be the Fast Flow Fuel Tap? maybe its faulty? I have eliminated everything else I can think of and have read about.

No, the fast flow tap only lets more fuel be possible. The float stops it from coming in and flooding. I don't think you are clear there yet, only improved.

This.

The fuel tap flow rate makes no difference with stopping flooding. The needle is not sealing into the float seat properly. Can you share photos of the needle, the float, and the seat?

There are two sizes of needle for si carbs, 4.7 and 5.2mm. Start there. We *just* covered leaky needles over in John's build thread, so he's already cut some trail on this one for you.

Ok here are pics of the needles, seats and floats. And the pin (which I used for both seats) red O is for old N for new. S for spaco d for dellorto

It looks like the top needle is a 5.2 and the bottom is a 4.7.
