Spanish 150 series 2

[kevspeed]

Hi all,just wondering if any of you can give me positive answers to a few questions relating to Spanish Li 150 series 2 models.
1; Do they all have the 'short' series 1 type barrel fitted as standard?
2; Do they also have the 'MA 19mm' carbs fitted as standard?
3; Are the gearboxes the same ratio's as the Italian models,or do they have the same as the later Spanish 150's?
The reasons for the questions are this,out of the 3 other Spanish series 2 models i have worked on in the past,all three had the series 1 type barrel,but all 3 had different carb set ups,one had an SH/18,one had an SH/20,and one had an MA 18mm,and lastly,as ive not yet had the gearbox out of one,im hoping its the Italian ratio's.
The machine im working on at the moment has the series 1 type barrel,and an MA 19mm carb,so im trying to keep the motor (as its the original one) as standard spec as possible!
Thanks in advance..............Kev

Can't answer the question about the barrel as I never used the original engine but my old '62 had MA carb and same gearbox as Italian li150.

My Spanish series 2 "winter model" has the shorter series 1 barrel and an Sh1/18 carb.

Happy days for the gearbox then,just the carb to sort out

Isn't 'standard' a bit of an oxymoron where Spanish Lambrettas are concerned

I know they have made various changes in design and fitment of parts over the years,but when I find a ,series 1' barrel,with a series 3 carb,it does set alarm bells ringing!
I have been so used to Italian models that I expected the Spanish to follow suit,but the mish mash of series 1-2 & 3 parts is quite surprising!!

1. Short barrel was used on all series 2. And early series 3. They changed it to the longer barrel somwhere in the 06**** range of numbers. Al the specials used the longer barrels
2. Early series 2 should have the ma 19 for 150 models never had a really early 125 model, so can't comment. The sh18 came in in1962 and was fitted to both 125 and 150, s. The only 150 have seen with the 20mm carb was the specials but most of them had the 18.
3. All series 2, s had the Italian ratio box and series 3, s up to 05**** number range, Specials had the Spanish gearbox with the large jump from third to 4th engine numbers start in the 30**** range. The 06****, 07**** range of numbers is where I'm not too sure of the gearbox .
A quick guide to date the engine is the first 2 numbers, it is not entirely accurate and only works up 1965
00 1960
01 1961
02 1962
03 1963
04 1964
05 1965

The Spanish series 2 barrels should also have LL cast in to them

Pilot 45, choke 50 and main 107. Not sure about the slide 5914-2 I think.

Strange lot these Spaniards!
Right,next on the list of 'Why change something that works as it is',............Spanish series 2 speedo cable!!!!,thread too big for the Italian cable......WHY??,and any idea where i might get one??

A genuine Spanish early type round series 2 speedo, were made in Spain and are unique to that scoot, I would think that the manufacturer will have made speedos for various motorbikes and used the same mechanism in them all, just changing the outer casing, you will probably find other bikes like montesa and bultaco use the same thread

I used to have some in stock but I think they are all gone now. Strange thing is I got them from one of our Italian suppliers. I will try and get some more next time I go down but it will be November.

The Spanish altered a lot of things some of which were for the better as they were building scooters that innocenti had had in production for over a year, so where problems were arising with Italian scoots the Spanish could rectify the problem before production started
For instance if your scoot is a 1962 or after you will notice that the crank case has the strengthening ribs round the kickstart shaft. They also had access to they latest technologies from innocenti so you see many series 3 parts appearing on the Spanish series 2, s.

Just got hold of an original speedo for a Spanish S2 and have hit the same problem. Does anyone know where I can get a cable (or just the top nut) to fit it? The connection at the back is 12mm across the threads whereas the Italian one currently fitted is only 11mm.

I will also need it refurbishing and assume Jem will be the recommendation
