Nice work on the banana though. How long is the running in process?

I look every day but there's been nothing of interest to me.
Maybe something older for the next project. Keep it rusty looking (but give it a wash obv) and bang a quicker engine in there:

New coilovers fitted.

Been out on the road with it and it goes really well. Lovely torquey engine, loads of power and no silly on/off power band.
Gearchange still needs slight adjustment



New alloy split rim tubeless wheels have arrived too. Just waiting for the fitting paste to arrive before fitting.

It's not the welder that will put you in hospital. I only get minor burns and electric shocks from mine. Aside from actually setting myself on fire the other week, but I spotted that and put it out before injury occurred.

It's the related tools that will get you. Angle grinders, chop saws, etc. They're the ones that are really out to get you.

Actually that is true. I have seen the accident reports from dockyards building warships. Angle grinders appear time and time again. Welders not so

The picture you posted was of a rim only. I assumed that, in common with bikes, cars and proper motorcycles, you need to lace the rim to the hub via some kind of spokes (i.e. build the wheel). This is a non-trivial skill in most cases hence my question.

From other pictures it looks like, in the case of scooters, you maybe just bolt the rim straight to the hub requiring little/no skill.

Ah I understand. I thought you were being a cnut.

You're right the wheel just bolts to the hub.

What did I say?

"The wheel just bolts to the hub"

Yes. And then the utterbastard lightly rubs on the clutch casing due to the wider lip on the wheel.

It took me 4 hours to find that out which included having to remove the hub and brake pads JUST to get the bloody wheel off because the exhaust is in the way and it's easier than removing the exhaust. You'd think after I'd spent that much on a pair of wheelbarrow sized wheels they'd fit, or if they didn't there'd be reviews warning about this? No bloody way.

I also put the tyre on the wrong way round (it's directional) so I had to take it off again.
4 bloody hours! To achieve zero!


Finally after posting my problem on a Vespa FB page someone had the same wheels and problem. Fortunately he gave me a link to a nine quid 1mm spacer that goes behind the hub and sorts (we'll see) the problem.

Well it's been too straightforward and successful so far, you surely couldn't expect to get all done without some bastard thing being a penis.

I had a feeling that this build had been difficult until I read the whole thread. Apart from threading the gear shaft and having to split and close the casings, and the clutch basket not fitting, it actually hasn't been that much of a nightmare which considering this isn't just some plug and play kit, must mean I'm not bad at this shit.

Now THAT has properly jinxed it.

The fitting paste for the wheels arrived but when I tried to fit the rear wheel it rubbed on the clutch casing because of a slightly deeper rim edge.
Luckily someone on a vespa forum had the same problem and there was a 1mm spacer kit for the rear hub which shifted it just enough for the wheel to fit.

It arrived on Friday and I fitted the wheels yesterday.

ID, it might be the pic, or I'm just looking at the wrong bit, but it looks like he studs/bolts holding the wheel to the hub don't have any threads showing - are they engaging far enough?

It's a combination of both. They are deeper than standard locking nuts and the studs aren't supposed to stick out. They are almost flush but the photo makes it look otherwise. Also some of them have tyre soap in them so look "empty".

Went for a 90 minute ride on Sunday On a plus note the engine is loosening up nicely and it feels really quick with bags of torque right through the range.

On a minus point that gear/clutch problem is still there and I'm fvcked if I've heard of the problem before or know the deffo solution.

Riding along on a 1/4 to 1/2 steady open throttle in 3rd or 4th (but not 1st or 2nd) and it feels like the clutch is dipped for a split second.

There are two opinions:
1. There is a clutch problem
2. There is a gear/selector problem

1 is fairly simple, 2 means splitting the engine.

I don't have a problem doing either but I'd like to know exactly WHAT is causing the problem so that I know I'm going to cure it by doing X. When people don't know exactly it could mean I do both and it's still the same. And to make it more difficult I changed both the gear selector and the clutch so I can't narrow it down that way.
Bollocks.

Do the easier/cheaper one first. Or seek external assistance.

Or pour petrol on it and burn the fcuker.

Certainly sounds like the clutch. If you're going along under the conditions where it sometimes happens and apply a bit more wellie (for example because you have got to a hill) does it start doing it worse?

No and it doesn't do it if you give it a wristfull of power. You can blip it on and off and it's just normal then back off and at a constant quarter throttle but accelerating slightly (if that makes sense) it'll do it.

Heres an audio interpretation: laaaaaaaaaaaaaaa ba!.laaaaaaaaaaaaaa ba! laaaaaaaaaaaaaaaaaaaaa. ba! laaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa ba!


The ba! is when it's like the clutch being dipped really quickly.

What's the chain and sprocket wear like? Just wondering if the chain isn't seating properly on the sprocket, whether it might build up tension and then suddenly release.

Just thinking outside the box.

Oh, I see... well that doesn't sound like the clutch. Are you sure it's the transmission at all? The ba! sounds like it's too short a glitch to call it an actual change in engine speed. I'm wondering if it might be the mixture. You've done some fairly major stuff to the ports and put a different exhaust on, but (without looking back through the thread) I don't remember what you've done to the carb to adapt it to the new conditions. I'm going to guess that wherever you got the details from about how to edit the ports also gave you some recommended jetting specifications, but they're unlikely to be exactly right as given, more likely they're better regarded as a starting point for experimentation.

If you can find somewhere you can ride it along for a mile or so in a continuous state of laaaaaaaaaaaaaaaaaa ba! laaaaaaaaa, then switch the ignition off, pull over and whip the plug out, you can get some idea of how close to correct the mixture is at that point in the operating range.

Also, it's good practice to make sure everything about the ignition system is spot on before investigating something that "ought to be" a mixture problem, because sometimes the symptoms are very similar.

Doesn't do laaaa ba in 1st or 2nd. Worse in 3rd not as bad in 4th so it's gear /clutch /drive shaft /selector related.
Done a plug chop and it's acceptable for the moment.
