Damn you man!
I looked to see how much they are just to tell you it's not worth buying a set for a few holes... and I ended up buying a set because they were much cheaper than I expected. 21pc Draper for £15


:laugh:

We are witnessing the descent of a man on his way to full-on spannering.


Tell me about it.
So far: Socket set, 2 spanner sets, feeler gauges, centre punch, circlip pliers, soft hammer, torque wrench, boxes of nuts, bolts, washers and locking washers, Dremel, new drill, vernier caliper, soldering iron and a bloody hydraulic scooter platform.
And that's without the bearing pullers, clutch puller and various other specialist Vespa tools.


Glad to assist your path to bankruptcy: you've probably almost got enough there to be able to change the clutch on an Audi... :)

Oh don't worry about that clutch, next time it goes 5 litres of Esso should sort it out.

Well shit and fvck.
The front brake was sticking so I decide to strip it and grease the actuator arm.
PING! the tiny brake shoe circlip flew off and was lost. Ok so I stole one off the rear pads but then noticed that the brake cable was fouling in the headset because I'd routed it incorrectly.
Time to totally disassemble the headset:
Headlight out
Speedo Out.
All cables disconnected.
Levers off.
Headset removed.

Then I find I'd assembled the twist tube incorrectly. After much time I got it right then reassembled the whole lot.

Four fvckinghours! With nothing to show for it as the brake STILL stuck on a bit- although not as bad.

Fitted the choke lever

Image

Fitted the CDI unit to the Engine:

Image


Then I thought I deserved a treat and decided to take the orange one for a run.
Lovely day- check
Scooter starts- check
See tiny pool of oil on floor- shit.
Fvckit! Went for a ride and it rode beautifully.


Anyway this has just had a full rebuild so it should be perfect but maybe there's too much oil so it's just spat it out.
Also it's been ridden a couple of times since I had it back and it's been as dry as a granyfanny.
So last night I put a piece of paper under the engine and tightened the sump plug slightly just in case.
This morning there was one tiny drop on the paper. It might be some of the residue still dropping so I wiped underneath and put a clean paper there. Trouble is it looks as though it's coming from the gear selector shaft which is an engine out and split job. Next problem is it's booked to be transported to Italy on Thursday and I have flights and car booked to meet it on the 20th.

CAN I GET A FVCKING BREAK PLEASE?

That'd be like shagging the ugly fat bird at the school disco: easy, unfulfilling and you wouldn't want your mates to see you riding it.


Anyway, the god of tools might have given me a break. After some research it appears it might have been ovefilled with oil plus it should have pissed oil straight away if the gear selector seal was knackered. Yesterday I wiped all of the oil from the engine, tightened the sump plug and released the excess oil from the filler plug. This morning there wasn't a drop on the piece of paper I put underneath.

Fingers crossed.

Took out the orange one for a long ride on Thursday and got it up to 90kph.

Parked it up with a piece of cardboard under the engine and 24 hours later, not a drop of oil.

Loaded it into the van and took it to work ready for collection by the courier.
Opened the van in the afternoon and there was one drop of oil on the floor.
Bastardshit!
Well screw it. Courier is coming today and I've cancelled twice so the orange shit can go to Italy anyway.

Ok back to the red bugger.

I'm waiting for parts so not much to do this week.

Painted the original number plate. Seemed nicer to restore it than put a shiny new one on it

Image
Image

Then drilled a hole in the tool box and fed the regulator wire through and then mounted
it in the engine area. If I'd put it in the tool box area I wouldn't have been able to fit the toolbox insert.


Image


I know it looks wonky but it's lying flat to the body and it's the only way it would fit.

Yet another thrilling episode in the Little Red Bastard Restoration.

Yet again- wrong bloody parts.
I ordered what I thought was the right lock for my seat. It appears that he put a 3rd Gen Primavera seat on it
meaning that the lock was wrong.
I tried taking them both apart to swap the barrells but just ended up with lots of bits that didn't fit.
So I drilled out the bastard.

Image


Then I thought I'd fit the locking post. Nope. Not long enough. Ordered what I hope is one that's long enough.

Image

I then went to fit the closing lever on the side panel but it appears the door needs a lock, which he supplied but without the bloody keys. Back on ebay.

I went to fit the two centre rails on the footboard and found that instead it needed a centre floor mat, which I'd sold last week thinking it was surplus. Back on Ebay.


Ok. Finally something went right. I fitted the stator
Image

Then the sports exhaust which amazingly had all the fittings and actually fitted.

Image

Then the flywheel which had the right nut and washer amazingly

Image

Then the plastic engine cover and flywheel guard

Image

It now looks like an engine and bar lengthening the stator wire it's ready to go into the frame.


So it started badly but improved.

Now I'm not an expert in building two stroke expansion tanks but that looks as if it has been shaped to fit the available space rather than to create power, particularly at the top left of the tank where a wedge is cut out. I'm pretty sure it wouldn't be too difficult to make a much better exhaust than that.

Sik you're right and there are hundreds of pipes out there but it would probably mean re-jetting or a change of carb... and then inlet pipe and then.... maybe a bigger fuel flow tap and ..... before then I would have set fire to the little bastard.

You might well have to piss with the jetting anyway, it's the sort of thing that tends to happen with any significant alteration to a two-stroke exhaust. Can't see you having to change anything more than jets though.

It's wrong in all sorts of ways. The step change in cross sectional area is the worst bit, but the whole shape looks wrong and I don't think it's just the perspective of the photo. And the whole thing is much too small unless the engine revs like a mosquito, which I don't think they do. It looks like much the same kind of deal as you get with chainsaw exhausts, where you just sack the whole idea of exhaust tuning off entirely because there isn't room and all it really does is take the edge off the noise.

That's really the problem - while it would indeed be fairly straightforward (given the relevant data plus Deuts-level metal-bashing skills) to make a better design, with the engine where it is there's nowhere to put it, unless you do something horrible with most of it sticking out.

Centre floor mat fitted. Utter shit of a job as you need 3 hands: 1 to hold the screwdriver, 1 for the screw and one to stretch the mat so the holes line up under the metal strip. Anyway, it's done.

Image

CDI unit wires lengthened and soldered then the engine was fitted.
Easier than I thought it was going to be.

Image

Wheel fitted
Image

Side door lock and panel fitted

Image

And from the other side

Image

It now looks like a scooter.


Now as we know all this stuff going right means there must be some shite due.
I fitted the carb and found that the accelerator cable inner was about 3 cms too short when the outer is placed in a holding slot on the carb.
This is despite ordering a complete set of cables for the little shit.
Another problem is that there's a welded-on blob on the carb end of the cable which slips into a v shaped slot.
This means you can't just pull out the cable and put in a longer one. Instead you have to fit a complete outer cable too which means threading it through the frame. An utter shit now the frame is all together.

I have two options:
1.Cut the end off the cable, dismantle the headset and thread in a longer cable then fit a screw on cable nipple.
2. Some how remove about 4cms of the cable outer at the carb end which will allow the outer end to be nearer the carb and so the inner should reach. But how the shit do you cut an outer cable without cutting through the inner? Because you KNOW that's going to happen and I can't remove the inner as the blob on the end means it won't go back up the inner and out of the way.

Typing this now has made me think of a 3rd way. Cut of the blob on the inner, push it up the outer and out of the way, cut the outer cable, thread the inner back through and attach a screw on nipple.
Yeah, that'll work out just like I typed it.

Anyway after that I have one more wire to lengthen, gear, clutch and rear brake cables to connect, the light switch to wire up, fuel tank to fit and seat post to mount and it should be finished.

One question: I can't do the timing as I don't have a strobe. If I try and start it and it's set wrong (no points btw it's a 12v system) what will happen? will I do any damage or will it just not start/run?

Remember to cut the cable with either REALLY sharp by-pass shears or a Dremel with a cutting disc or it'll fray like a bastard and you'll not thread it anywhere.

Re the timing, yes if it's too advanced it'll pink/knock its nuts off and potentially do some serious damage. But if you're careful you can listen out for it as you keep advancing the timing and then dial it down just a notch as soon as you hear it knock.

Good point but luckily it doesn't have to be threaded anywhere after I've cut it. The end will just slip into a barrel shaped stop.
It's the bit near the green arrow hidden behind the vertical sliver bar.

Image

As for the timing I think I'll take it to be done at Wildcat scooters who did the orange one.
I bet the carb needs setting up and there are bound to be electrical shit that doesn't work so they can do it all at the same time.
With so many setbacks I've had a titfull to be honest.

A pointless day.

Engine out and wire lengthened.
While it's out fitted all new fittings for the cables so they'll be easier to adjust.
Engine back in, wires connected, cables threaded through and just need adjusting

Throttle cable changed. Easier than I thought although I found out the stop lug wasn't stopping the throttle turning all the way around and so pulled the cable out of the mounting. Twice. All sorted now though but the throttle twist is a bit sticky and doesn't return on it's own- another one for the snag list at Wildcat scooters.
Seat post mounted.

Thrilling eh?

Oh for fvcks sake!

As the engine is now back in the frame I thought I'd check if the kickstart would turn it over.

Nope. Jammed.

Massiveswears!


This means engine out and split again. Then all back together again.



There is a 5 litre can of petrol on the floor of the garage.
I'm sorely tempted to add it, and a match, to the little red bastard.

Oh if only the kickstarter had been jammed!

No this is far more serious.

I removed and stripped the engine and discovered that the reason it wouldn't turn over was because the crank was touching the case near the exhaust port. AND there is a lovely gouge in the casing all the way around where the crank rotates. I didn't notice this before as when I built it the crank was in the damaged side of the case, covering the marks. When I split it this time the crank stayed in the good half and the shit was there to see. I've no idea where I go with this now. Worst case scenario is new casings at about £500. Maybe second hand at about £300. Or maybe it can be repaired and the sticky-out bit dremelled. Trouble is I don't know why it happened in the first place.

Here are the gouges. They aren't as bad as they look in the photo though.
Image

You can see where the crank is touching the case at about 2 or 3 o'clock on the photo if that makes sense.
