I can tell the machine shop that is forged piston when boring/honing the cylinder. They should know the correct clearance, or the manufacture should give us a note about that, I believe. I've heard the negative point on forged piston that there would be the hard starting issue. -Palmgo

I think I've uploaded most of my tools here.
http://groups.yahoo.com/group/vespa-sports/photos/album/140581569/pic/list

I've used various adapters, spacers or collars in addition to these. These are
found in my tool box/garage and not even a product but pretty important tools
IMHO.

You will need, additionally, a clutch extractor. Cheap and easy to buy. A gudgeon pin remover/press tool is handy, too. Sometimes difficult to source, strangely enough. A blow lamp for heating up the crankcase for main bearing removal is a must. Drifts for tapping the hot bearings out (thick gloves are handy, too).

A ten ton press for bearing replacement and a boring and honing machine for reboring the cylinder....Only joking!

Small end bush replacement also requires specialist tooling and, as in the last para. , best left to someone who knows what he/she is doing.

Not sure why you want: Blind bearing puller and Bearing separator? Also, the crank seal punch might be nice, but not mandatory.

The steering tools can be found in most bike, as in: ‘push bike’ shops. Bicycle nylon tyre levers are handy, as they don’t scratch the rim paint. A length of M10 studding + two M 10 plain nuts and a bunch of large washers to make up a tool to press in the bearing cups into the chassis

Perhaps, a metre long breaker tommy bar for hub centre nuts? Cheap an’ cheerful versions from the far east are OK.

A spare engine bolt. Handy if fitting an engine into the chassis when single handed (one goes in from either side and the engine bolt knocked through).

A scissor jack to support the engine/chassis, especially if you are working on your own.

Two bricks or a large piece of lumber to put under the stand feet to stop the stand springing up when the back end of the scooter is jacked up. Bricks are nice as the feet can sit in the frogs.

I have a personal preference for the 10mm and 8 mm ratchet ring spanners (sold in Halfords) for the awkward jobs where a socket won’t fit and there’s only a small ‘throw’ to be had. I also am addicted to disposable rubber gloves! And a pack of zip up plastic drugs bags to keep small parts together (you can easily use 50 of these).

Think that’s it?

GS has regular nut on the clutch, 14 mm I think?

However you will need a clutch puller.

Flywheel puller is a helpful thing to have (just a 3 prong puller) and also a clutch compressor.

Also you know my opinion on blind bearings... I was told the only way to remove them is to heat the case 400F in the oven and than just tap it on the table top, bearings should fall out. Bearing puller is likely to destroy them

if using forged piston have to make sure the jetting is spot-on and so are the clearances.

if anyone wonders about the difference, normal pistons are pressure cast, but forged are stamped out by a giant press from a blank at near melting temperature. Both are after machined to shape

Annoying fault....

Assuming the clutch has been properly rebuilt and nothing is missing, there is a chance that the cush drive needs overhauling. They do ‘give up the ghost’ and when they do you lose engine damping and power take up problems can occur. Sadly, this is the last thing to come out of the engine on stripping the lump down. Breaking up of this part – a rare occurrence – can be terminal for an engine. I note that it is also the very last thing that people dream of rebuilding. It’s a cheap and reasonably easy job, so I’ve never understood why it’s not done. External examination of the cush drive rarely shows up any problem inside the retaining plates, by the way.

My very own GS 160 tended to snatch on take off (under load up hill and with a pillion). Rebuilt the clutch paying notice to the steel plate direction and it then ran perfectly. This, as you say, is not your problem. On the whole Vespa clutches are pretty bullet proof and exhibit no faults if correctly built and fitted. If you had a spare clutch, I would try that. Unhelpful comment if you don’t have one, of course!

Finally, how about taking the whole thing to a vintage Vespa specialist work shop? That never fails!

Super-Sporters:

My clutch issues continue after two clutch rebuilds.

First of all, watch the video and listen to the sound from neutral to
1st gear and then note the wheelies the bike pops -- this is the
clutch issue:
http://vesparestoration.blogspot.com/2009/06/another-ride-and-whats-left.html
Those are the two problems.

Here is a brief write up (Paul, there are also 3 other new
recommendations at the bottom of the post):
http://vesparestoration.blogspot.com/2009/10/clutch-issue-continues.html

We identified that one of the spacer cones and the clutch tension
washer were missing. Those are now installed. All parts appear to be
in good working order, except for one of the divets that holds the 1
of the 3 springs in place during compression looks a little worn out.
And the needle bearing appears to have some space between the rollers
as opposed to filled with rollers as most bearings are. The person who rebuilt the engine installed brand new clutch plates (from ScooterWorks) and they do not have scribe marks on them or appear concave.

The clutch is currently open and I plan to photograph and video it
tomorrow in order to show my mentors what we're working with.
Suggestions for what you need to see Tom?

I wish it were something as EASY as the clutch cable not properly
tightened. Wouldn't that make this easy?!

Advice to try on the clutch? I am hoping not to need to split the cases and work on the Christmas Tree or anything internal unless I have exhausted all other options first.

The solution is easy....
Do 2 runs.... 4 sizes first run for the people who want it Stock- 2nd over for a GS and a 2nd over for an SS. Sleave your cylinder to suit if need be,.
The second run could be 4th over for GS and 4th oversize for SS, both are dangerous for original cylinder that should have to be "sleaved and honed" anyways. Either that or take a collective favorable count. Its easy to sell the extras to any vespa shop on either land mass. 6grand is the estimated cost.

I just had Rally piston welded up to make a 200+ cc Hurricane piston, I think there will be less market for that than 2nd over GS or SS piston.

Also what piston are you going to copy? Piaggio I hope.

I'm down for one of each if it helps get things moving. There are few people around here that might jump in, will ask around this week, I recon I can get couple more pre-sold, most likely GS

Hi,

Mark Broadhurst has had forged pistons made for Lambrettas. He says they are made by a company that manufactures pistons for formula one racing car engines and are, therefore, are fitted with Dykes rings. They retail at about �120. The smallest piston size sold is for a 200 cc Lambretta. Mark has a good moan about current piston quality (i.e: not those sold by himself!). He would have it that even Assos pistons � for instance - that are sourced in Italy are actually made in India, but he says the real problem is not so much with the pistons as a casting, but with the rings that are made from a low grade cast iron and tend to break. I do think, however, that the suppliers of our spare parts could be a little less disingenuous about the origin of the items that they sell. This is effectively Mark�s point.

For those not following the plot here. Forged pistons are made from a solid billet of aluminium alloy and pressed into shape rather than being melted and moulded as cast pistons are. The �forging� of the base metal �lines up� the metal at a molecular level and makes the end product far superior to a casting that fails to achieve this desirable characteristic. This is only my understanding and I�m no expert, however! In either case, machining is necessary to complete the end product.

As a side issue, not everything made in India is of poor quality. The problem is sifting the wheat from the chaff. As in: you have no idea if the part you are buying is of good or inferior quality. The home, that is to say � Indian home market is remarkably resilient to inferior quality goods and the national concept of quality control varies according to the whim of the manufacturer, or so it would appear to consumers from countries used to a quality end product? This is a particular issue for the modern Lambretta owner, as many spares for this marque are sourced in India. This factor seems to be creeping into the Vespa side of the camp. The last model PX 125�s are said to be made in India, given Italian electrics and then flogged on as Italian! What other shennanigans are the spares manufacturers up to? We will, in all probability, never know until the part goes POP?

Not terribly helpful, my rant as above, but starting with a few questions at Mark Broadhurst�s door might just supply a decent manufacturer for pistons, that�s all...

We're making the foam inserts for the back now, so if you wait maybe 2 weeks then add a comment when ordering and we'll do the padding for you. The one shown in the photo there, which we were told is original, had foam going over the sides, plus a hard base, plus the end flip tail insert.

Can we split the difference you saved over $250? Or buy me a Guinness some time ;-) (I just had a horrible Guinness out of a can last night. No real Guinness here.)

Hi,

Mark Broadhurst has had forged pistons made for Lambrettas. He says they are made by a company that manufactures pistons for formula one racing car engines and are, therefore, are fitted with Dykes rings. They retail at about £120. The smallest piston size sold is for a 200 cc Lambretta. Mark has a good moan about current piston quality (i.e: not those sold by himself!). He would have it that even Assos pistons – for instance - that are sourced in Italy are actually made in India, but he says the real problem is not so much with the pistons as a casting, but with the rings that are made from a low grade cast iron and tend to break. I do think, however, that the suppliers of our spare parts could be a little less disingenuous about the origin of the items that they sell. This is effectively Mark’s point.

For those not following the plot here. Forged pistons are made from a solid billet of aluminium alloy and pressed into shape rather than being melted and moulded as cast pistons are. The ‘forging’ of the base metal ‘lines up’ the metal at a molecular level and makes the end product far superior to a casting that fails to achieve this desirable characteristic. This is only my understanding and I’m no expert, however! In either case, machining is necessary to complete the end product.

As a side issue, not everything made in India is of poor quality. The problem is sifting the wheat from the chaff. As in: you have no idea if the part you are buying is of good or inferior quality. The home, that is to say – Indian home market is remarkably resilient to inferior quality goods and the national concept of quality control varies according to the whim of the manufacturer, or so it would appear to consumers from countries used to a quality end product? This is a particular issue for the modern Lambretta owner, as many spares for this marque are sourced in India. This factor seems to be creeping into the Vespa side of the camp. The last model PX 125’s are said to be made in India, given Italian electrics and then flogged on as Italian! What other shennanigans are the spares manufacturers up to? We will, in all probability, never know until the part goes POP?

Not terribly helpful, my rant as above, but starting with a few questions at Mark Broadhurst’s door might just supply a decent manufacturer for pistons, that’s all...

Dave

I think we got it started at some point before it came apart.
