Modern Vespa

Well that explains that! Thanks. I know it doesn't mean shit but the fork even has 58 Allstate written on it. I ground in a new one so all is good. Went as light as possible and kept fitting it until the screw finally slid in. That way it's impossible to take out too much.

Yes it has the dreaded JBWeld. I'm going to tackle that when I paint it in the future. Steering stops are good.

I thought this type of fuel line was ethanol resistant. Oh well. I'll grab one soon.

My welder friend had covid so he finally got back to work and tack welded the studs on the seating jawn.

Just waiting on the cables to arrive today then I'm good to button her up. And then chase 100 electrical gremlins cause I'm sure that won't be a smooth painless experience.

Just in time too. Today is frigid. But it's supposed to warm up this weekend into next week so I may get a ride in before the big freeze sets in soon.

For future fork notchings, use a flapper disc with a bullnose on it. It can quickly give you factory like results.

Good idea! Hopefully I'll never need that but one day someone may.

Does anyone have any tips on getting the front brake cable to seat in the lever perch properly?

If you look inside you see there's a stop in there for the cable inner to go through and blocks the outer from being pulled through. However there's also PLENTY of space behind that for the outer to pass. I can't seem to get it to not pass the stop. Which then doesn't allow for the brake to pull properly. Halp!

Here's another maybe better pic. Am I missing something in both of the headsets I have or is this user error? I didn't have an issue at all when I put Bluey together.

Do you have a tophat behind the perch for the cable to sit in? It still goes thought with one?

Does the top hat sit outside of the lever housing? Like so…

put the tophat on the inner and feed it through from the lever side? Tophat should definitely be seated into that slot. On all mine, it has a rounded hole for the top of the tophat and a slot for the cable, so it looks like a keyhole.

Remove the tophat.

Run the cable though it and clamp the other end with a third hand tool or a cable stop.
With a flat blade screwdriver to direct it, pull the ferrule up into the seat with the cable.

Thanks Chandlerman and Ray!

Had a brain fart apparently and never even thought to try that. Got that part sorted then went to town on the f@$@)#g throttle nonsense. I think I got that sorted too.

Time to kick her over after lunch and see what's up

Gr8.

Just to be clear, don't use the tophat.
There's a socket in there that only a ferrule will seat in.

Now ya tell me! Guess that'll get fixed once I brake the cable or something.

I have a top hat on mine. Brakes well. If the top hat fits between where the cable goes through I'd leave it. The diagram shows no top hat but one on the clutch side. It's the opposite on mine, weird.

Moving on to the first start. Did it. Ran for about 30 seconds then died. Won't restart. I have spark and a new fuel line. The fuel line is rubber so I can't see if there's gas in it. How do you all test for flow from the tank?

Going to toss the clear Toyox brand one or whatever it's called and see if the gas gets to the carb later. Wanted to see if anyone had tips on how to check the line prior to that.

It's messy, but if you loosen the screw on the float cover, it'll leak all over the airbox if it has fuel.

I was hoping to avoid mess. So it goes I suppose. I'll try that tonight before I swap the hose.

is that even possible with a vespa?

Absolutely not.
They make my chicken coop seem pristine!

I should correct myself - my GTS doesn't seem to soil the digs. But modern is a different world.

Yahtzee! Pulled the float cover all the way off and zilch gas flowed. Will swap the hose this weekend if I have time. Thanks!

You avoided the mess!

Yeah, that's the irony. If you avoid the mess, you're going to have to make a mess.

Interesting development. Leaving me more confused.

Replaced the gas line with the clear one. Noticed the fuel tap was backwards. Ie Closed was reserve and reserve was closed. So I flipped that back around to the correct way. Before I did that I emptied a small amount of gas from the tap to make sure that wasn't the issue. Gas flowed fine.
Put the clear hose one and attached it all up and put gas in the tank then opened the tap. Nothing. Tried all 3 positions with the gas cap on and off. No flow. Pulled up the tank to try and see if that helped. Nope. Pulled the tank and rested it on top of the cavity and tried the tap again and no gas. Wtf could be causing this?

Vent hole is clear as far as I know since the gas didn't flow when I opened it up so it's not that. But I'm stumped. Brand new line, 24" long like it should be, no kinks, tap works but no fuel flow. Any ideas?

That's bizarre. Only thing I can think of is bring it back to the source. Prop up the tank with some gas in it and check the tap fully opened.

I know, you did this, but fully opened? Watching a stream come out of the tap? Gotta catch it somehow and all, but I can't think of what else it could be...

Hmmmmm

I'll run through it again. Can't hurt to at least. It's gotta be the tap somehow. May as well take that out and clean it just to make sure also. Its gonna be in the 70's tomorrow and Tuesday here so I'm hoping to get a ride in then. Fingers crossed.

Update.

Took the tank out and put gas in. Opened the tap. Well didn't have to open it. Gas came right out. Turns out I didn't fix the backwards tap lever thingy. So closed was reserve and out it came. Quickly closed that off so not to make a huge mess and got to testing.

Test One- tank out no hose attached:

Lever in off works as reserve, fuel flows.
Full open is middle and no gas comes out.
Closed is the reverse setting and no gas comes out.

Test Two- open tank cap while working the lever. No change in any position from above.

Test Three- attached hose, tank on top of frame

Lever in off position, gas flows about 10" down the line where it stops.
Full Open middle, no gas flow
Reverse, no gas flow

Test Four- hose attached, tank in frame
same results as Test Three.

I'm stumped. Gonna take apart the tap tomorrow. I got my sons hockey game at 6am tomorrow so I gotta go to bed now.

How bizarre how bizarre

How does the tap work backwards? Like the lever is installed upside down, so that the open position is straight down instead of straight up? (I'm just assuming it works the same as a smallframe one)

Mike,

i suspect you have the disk valve installed backwards. you should rotate it 180 degrees and i reckon this will resolve your VNA fuel petcock issue.

Yeah.
You can see what's happening in your test here. "Closed" is reserve and the rest is off.

So I wanna make sure the blocked off hole is on the right when I reassemble it? Or is that a picture of how is should look already and that's what I wanna match?

Thanks! Dang user error. Although that's better than something being broken. I thought I rotated it but I think I just must have spun the piece that the lever sits in instead of the whole shebang

Just rotate the disk 180, so the channel is positioned as in red when the lever's closed. Currently it's in the yellow position.

Thank you! The visual is a big help. Appreciated!

Well it only kinda helped. Helped me see that no matter what I did, the tap only let gas out on the off setting.

Makes sense since my lights also only work on the off setting. Seems to be a thing over here. Going to try the second tap I have and see if that one is kosher.

Stay tuned

I don't know why I'm struggling so bad with this fucking tap.

I'm about to blast them into the sun. Been at it for over an hour now and still only works when closed. Both of them. So it's user error cause they sure as shit worked before. Maybe I should eat something. Before I set this whole damn scooter and house on fire.

Hang in there! I've been there before trying to figure out just which combination to position the disc, cover plate, and lever at. It was definitely perplexing for me to get them all correctly placed.

Which taps are you using?
Maybe I can take a few more pics. Been meaning to drill-out a stock I have for fast-flow anyway. Also have an SIP v2.

SIP 2.0 if you could that'd be extra helpful. I feel kinda crazy right now.


Edit: GOT IT!!! Good lord that was painful. All kosher on the tap now though. Time to see if it flows through the hose now!
