Once engine was out frame and stripped I discovered that it was fitted with a standard px 125 or 150 base gasket which didn`t cover the transfer ports at the base of the polini barrel so I guess that is what caused my seize, after the seize I did continue to use the scooter till the end of the previous season with the carb upjetted and rich. This was an engine that I bought from gumtree and just bolted in and it went and had done best part of 1k miles before it seized. there is a considerable difference betwen a standard base gasket and one for a kit!

So last summer with help from this forum I rebuilt my polini kitted px125 engine as it had siezed on me, I also decided while the engine was out to get the frame and body refurbished so it was back to bare metal. The scooter is a early sixties GL using the PX motor and is all back together now and has an MOT. The engine got new bearings and seals and a clean up of the piston and bore to remove the scuff marks and I was looking for tips on running it in what speeds/throttle openings and for how many miles. help and advice appreciated as ever, and thanks guys as without the help I had received on this forum I wouldn`t have managed it. Ian Not sure if i`ve got photobucket to work right! i1084.photobucket.com/albums/j419/ian_martin40ianmartin40/image_zpsm4qyez2o.jpg<a href="http://s1084.photobucket.com/user/ian_martin40ianmartin40/media/IMG_2237_zpsebrtxasw.jpg.html" target="_blank"><img src="http://i1084.photobucket.com/albums/j419/ian_martin40ianmartin40/IMG_2237_zpsebrtxasw.jpg" border="0" alt=" photo IMG_2237_zpsebrtxasw.jpg"/></a>

From my limited electrical knowledge a diode must be fitted the correct way round as it`s job is to allow the current to flow in one direction only, the cathode is the end with the band painted on as in your picture it is silver.

For me the season hasn`t started yet so I would be inclined to open it up and see what you are dealing with, you could be lucky and just bolt it in, replace the missing parts and it may work, it is a question of do you feel lucky? I bought an engine from a seller on gumtree and it did work, not perfect but it did work until it had a big sieze, due to wrong gaskets being used. I know people who have bought from internet sites and been told how great the engine was only to find it needed pretty much everything and they ended up spending a lot of money. it does seem cheap for a 200.

To avoid cheap copies buy from reputable dealer/internet seller, remember the DR180 kits are not overly expensive either for quite a lot more go but I know the cost keeps going up

It will be a drop the front fork out of frame, so there is a fair bit to it as you will have the brake hose to deal with also. To make fork removal easier put scooter on stand and build up height by sitting stand onto concrete blocks or similar to lift it up, then secure rear wheel down which elevates front end giving enough clearance once all disconnected to drop fork out. on older models I can drop fork out with headset still connected but only attached by cables/wiring, it is prone to flopping about and marking the paintwork so helps to support it with bungee from shed roof etc.

Sounds like you are planning a rustoration which keeps the original look and patina but doesn`t allow the condition of the scooter to get any worse, some guys use wax based rust proofer and rub it in like a polish to the rusty areas or other anti corrosion products like ACF50 which once applied again you polish off leaving just a thin coating on the bare metal areas. From the ones that have featured in the scooter magazines the scooter usually gets dismantled, cleaned and treated and then re-assembled using new parts where required so you end up with a fully rebuilt and reliable machine which retains the look it had originally.

I did not think anyone actually did this and they just got paperwork from someone they knew, friendly mechanic etc, there are loads of px 125`s with 180 kits fitted and not declared, I`m not saying it is right but it is common, and what is the HP difference between a px 150 and a 125 anyway? even a px200 is less than 12hp! This is just DVLA and insurance companies making you jump through hoops to make you fit their criteria..... all of a sudden the home mechanic is no longer competent to fit an new piston, barrel and head and you need paperwork etc etc yet this is a job you can do yourself, the big bore kit makers supply all you need and if you buy from a reputable dealer they will also supply the carb jets needed to go with the kit if you tell them what you have and what you want. Rant over!!!!

the genuine ducati cdi units come without the lead and you screw yours in so as long as it is not a pattern version with a moulded on lead it should go back in.

post a picture Unless you are using a very expensive piston, you will probably remove it from con rod to change small end bearing anyway so why re-fit a suspect item? is it a standard item or part of a kit?

the px tuning feature to DIY tune your barrel was in last month scootering magazine, pretty much as above, DR kits are not too expensive either. back issues of scootering are available.

If the oil you drain out is dirty I would just do a couple of oil changes a week or two apart always draining from warm engine and that should clean it up, if the oil is continually dirty you may have other issues. Ian

Hi Guys I am having problems removing the front spring from my 1960`s Vespa GL, it is the old type with separate shock and spring, if I try to remove nut at top there is a plate inside the spring which rotates at the same time, is this the correct starting point? does this job require a full strip if front links etc? The reason for removal is old spring has been painted and looks a bit sh*t and appears to be a bit coil bound. All advice appreciated.

Scootering magazine did an exhaust feature and reckoned the sito exhausts were not a great fit any more and the sip was better performance and not much more expensive than sito+. However my mate bought the sip and loved the performance but did have a few choice words when trying to fit it.

May also be worth checking petrol has not also passed crank seal and contaminated gear oil, that happened to my mates px it was fine after a couple of oil changes.

To my knowledge the GL 150 was a 10 inch wheel model, and the 150 super a 8 inch wheel model

if t5 is your thing then go for it, if you don`t like the look of them then consider making your current px a bit quicker, drill filter, sports exhaust and carb upjet, maybe even a big bore kit, either way you will still be out enjoying a vespa win win situation, if feeling wealthy have both!

Hi Henri cheers for that it sounded too good to be true letting us carry on with good old 2 stroke as we know it. Ian

I had the exact same issue with mytyres when ordering tyres for my car, I even phoned them to confirm they were in stock, ordered them online and instantly received an e-mail saying out of stock, and all sorts of rubbish over the phone "they are being shipped from Germany", "stock take at the warehouse so cannot find them till next week" etc etc Buy from a scooter shop or known good online supplier

as far as I know a 1972 150 super was never anywhere near 14hp, even a px200 doesn`t have 14hp in standard form, there is most likely a 125cc kit you could fit, but most people I know on L plates are running big bore kits for more power and just changing v5 with DVLA to 125cc! not even nearly legal.

A question for henri How does the zero emission 2 stroke work? does it still run a total loss lubrication system? if it is still small and compact and doesn`t weigh much it has to be the way forward for small capacity 2 wheelers

Post by ianmartin40 on Sept 25, 2016 13:05:41 GMT
I bet if they were shifting thousands of them they would work hard to come up with a solution to the emissions problem, I am going to guess one of the reasons for not using other piaggio technologies is the cost involved in changing the vespa to make it fit as most other scooters use the central engine like a lambretta and not slung on the side, although LML managed to fit a 4 stroke engine after making a few major changes to the frame so it is possible. And don`t think for a minute we are safe with our older machines as they could well be outlawed in cities and other places with pollution problems as we are easy to blame as we are using 2 stroke engines which I really like.

As far as I know they are in Kilmarnock And I have only heard good reports about them from local scooterist. Worth a phone call if you have any doubts. Last time i needed engine rebuild stuff i used wasp in Morecambe.

I also have a std px200 which is good to ride, however I also have a classic vespa which is fitted with a kitted px125 motor and it is quicker than my px200 it is probably a bit lower geared but it has loads of torque and revs build very quickly, in the scootering magazine just now there is an advert for a BGM kit which is probably a high end article but they are claiming in excess of 15hp when fitted with a pipe and upjettted carb, that is a huge percentage increase on std motor.
There are plenty of kits to choose from starting with iron barrel ones which are very affordable for bolt on and go! I don't know of many std px 125`s left as most folk have carried out some sort of tuning work, just depends on budget and use.
