I have a 177 Pinasco kit on my VBB with a 20:20 Delorto and SIP road 2 - Had my jetting at 112 for the main but found it very rich, lots of white smoke so knocked it down to 100 as it was all I had on me and no smoke - brought a 105 to see how a middle ground size would be as I wonder if the 100 is too lean. Comes this week so will report back

Not the same Kit but here is an install video of a new Cylinder kit on a smaller CC Vespa - - might be of some help

I have used www.vespaman.co.uk/ and he will come to you! Based in SW London but I think he travels all around London. Have you checked your fuel flow? Length of fuel tube might be too long

For what it's worth I still think your clutch is dragging and cut out caused by lack of power from a weak engine. : ) Weak engine to do with maybe a worn stator? Or a flywheel that’s lost it’s magnetism?

Wow some of the replies on here...
In fairness I asked the question a while ago and got little to few responses for a few days so I didn’t return to the forum to check, that plus I have a job and a life offline. If that offends you or if you find it rude then there’s nothing I can do.
I always post on here and ModernVespa as there are different users and I find either forum more helpful sometimes. I didn’t realise it was a crime to post on both.
I haven’t got round to even look at the Vespa to check and try some of the helpful replies. But to those that have tried to help I will be trying today to see if I can fix the problem

So still having engine issues with the latest one being that the engine stalls when I select first gear and that’s when the clutch is pulled in! It doesn’t jump forward just dies as soon as it goes into first!
Vespa VBB 177cc pinasco kitted.
Could it be the clutch cable just needs tightening?

Thought I had fixed it but after a good 10-15 mile run tonight the bike started to lose power again and cut out in the higher gears.
Seemed to run ok on Saturday but tonight not so much and again struggled to tick over on idle without giving it some throttle.
My 55-160 jet came so I’ll try that to see if it helps otherwise I’m out of ideas.

So got my Mechanic to take a look - he is called Vespaman based out of Wimbledon vespaman.co.uk and can't recommend him enough He put on a new 6v stator a while ago as the 12v kit I brought and I made Atoms install was basically garbage - My fault really. So he set the timing and got it working for me when he finished up a few final jobs so I'm under the impression that its all ok. What we did discover though was that the fuel hose was just too long by around 10cm so it was restricting the fuel into the carb a lot which is sort of what I felt all along. Shortened that and cleaned out the jets and it runs as good as ever. He said I could potentially go to a 55/160 as I'm only running a 48/160 at the moment so I've got one of those coming and also down jet to a 105 or 108 but as its running ok at the moment to wait, do some more miles and check the plug regularly etc as I'm still running in the new cylinder and rings.

Took a look at the spark plug and it was coated in oil - taking that as a bad sign

Short lived excitement as tonight I can’t even get the bike to kick start.
Losing my enthusiasm and confidence in it all now

Managed to get it to idle well this evening, mixture of new fuel tube cut to 24 inches, clean out the carb float, jets. Mixture screws etc and fiddled with the choke that kept coming loose!
Then the throttle cable had come loose so tightened that up.
Least I got it to idle so tomorrow night I’ll take it back out for a spin to see how it runs.

How do I flush the carb? Complete noob to a lot of this

Post by antvespa on Jun 24, 2019 18:58:40 GMT
Tried new fuel - It still bogs down at low revs and the engine just dies when idling! Have to twist the throttle a bit to keep it going and this is with the choke out.
Seems fine in 4th now with loads of throttle - when it sounds the healthiest!

I'm hoping so - Did realise I filled it up with fuel that was over a year, I old grabbed the wrong Jerry can so my fault.

This may be a stupid question but could it be old Fuel with potentially too much oil in the mix that are causing issues??

Also the wiring has just been renewed and seems to working well so I don’t think that’s the issue.
Kickstarting seems ok and doesn’t take more than 1-3 kicks at the most to get it going. Compressions wise I’m no expert so I wouldn’t know what is good or bad

Checked the carb today and the jets are as follows 48:160 and 112.
The engine was rebuilt with all new seals bearings, new Marzucchi (spelling) crank and the work was done by Atoms in Maidstone, very reputable garage for Vespas down south.
They never had it running as I was sourcing a clutch when they were working on it and was over a year ago due to a long restoration.
Fuel tank is new as old was unsalvageable and the fuel tap is a new SIP fast flow one.
Today I took it out and it kept stalling at idle - managed to get it home but only keeping the throttle open!
So it seems the opposite of yesterday but it kept hesitating both days as if it wasn’t getting a rough fuel at any point.

Taken out my VBB150 for its first run down after a 3 year restoration (slow I know).
Took it out a few times and seemed ok but today went for a longer drive but only got about 3/4 mile down the road and it cut out in 4th gear! Try to give it more revs but nothing and it just died on me.
Has a Pinasco 177 cylinder head, 20:20 carb and a SIP road 2 Exhaust.
Any ideas? Is it not getting enough fuel or too much when in 4th? I admit I Don't know the jetting just what came with the carb!
Could it be a soft Seize? Didn't feel like the back wheel locked up at any point just the revs dropped and the engine died

Phone Bike sure and they wanted £910 for a 1960 Vespa VBB with no declared mods. I think not
I then called Footman James and got fully comp with a guaranteed valuation for £141 a month - Bargain - 0 no claims and only passed full bike test the day before
Pays to shop around

It has new cams al round.
I think I solved the clutch problem, the previous owner cut a line into the clutch arm so the cable was coming loose when ever the clutch was being pulled in.
I think with the foot brake i might need to sand down the fresh paint a bit more so it pivots on the arms a bit better and is not getting stuck

I have my engine in the frame and just want to get the engine going - right now I'm not fussed about the rest of the electrics. (still, have work and parts to source for the that)
I have coming out of the stator these wires:
Black Grey Green Red Violet
I then have a CDI with the following inputs
- G = Green or Grey - G = Green or Grey - R = Red - V = Violet - B = Black is ground which I know needs to be bolted to engine or body
- Red that goes to the Spark Plug unit
I have actually had this engine sparking and sort of firing but since then have had it de-assembled and can't remember what wires I had going where.

Working through my VBB restoration and getting to the cables.
Problem 1:
Is there any easy way of tightening the cable? I have used a draper cable tool but it just keeps slipping.
I have someone else pulling on the cable to pull it tight and then I tighten the Nipple clamp just before the arm to what I think is tight but when I test the clutch lever it won't pull in the clutch and then it seems slack.
Problem 2:
With the rear brake cable, I also feel like the foot brake doesn't spring back when it's pressed down.
This bike is fighting me at every step haha, I should just take it to a professional but I want to learn how to service this bike myself.
Any tricks or tips

Was the bike running before you painted it? Those wires look to have seen better days, whilst the bike is apart id look to buy a new loom or make one up and change them - I have a 12v conversion but there should be a black wire coming out of the main loom that needs to be grounded.

Do you have a good ground connection?

That actually makes sense Shaunbond - I'll call it the "Italian Cruise Control" feature

Currently working my way through my To-Do list and attaching the throttle cable.
When connected does the throttle grip snap back into place like its on a spring? or do you have to twist it yourself on and off?
Mine feels like there is no tension for it to spring back into place and wasn't sure if this was how they worked on vintage bikes
