Lambretta Engine Rebuild Part 1

I will not go into depth telling you how to build a lambretta engine because i no more about vespa engines, so all i did was use (Sticky's Book on Lambrettas) and asked for help from my friends anyway. As i was going to replace the crank it was decided that i would use a GP one as it means i can use a stonger GP flywheel, this was fitted with F.A.G bearings and good quality seals. I have been very lucky with the gear box as it was fitted with an italian ratio one and not the usual spanish one that have a bad third to fourth difference, again new bearings and seals were fitted

More Things Painted

The hub was stripped then blasted before painting then new bearing, seals and shoes were fitted. The brake lever is away with some other parts at the the chrome platers. The tank and other stuff were also blasted before painting

Lambretta Forks And Dampers

Right the plan was easy it was buy a Escort damper kit off ebay and weld on the top brackets, beadblast the lot and paint and put all the bits back together. So i striped the forks and waited for the kit . What a disapointment, when it did arrive the dampers chrome was crap and starting to go rusty, the welding looks bad and worse they had different damping from side to side. Anyway i did use the top brackets and paint them all up. The internals were in very good nick so they were just cleaned up and put back in with new bumper stops and new chrome bolts and cable guide. I have ordered some scootrs s.steel dampers

Sand And Fill

All the body panels have been sand blasted or beed blasted and welded up. The legshealds were in a bit of a state around the bottom edge so i have decided to use a stainless steel trim to add strength plus it also looks nice. I then panel beated all the dents out and skimmed them with filler

About Time

Its been a long time but i have eventually got on with updating this blog. I have been working on it inbetween the other stuff like the frogeye sprite, and the rally frame ( Pixs on my other blog see listing on side bar). I shall now try to catch up. The frame and body parts have all been sand blasted, there was a bit of rot on the hoop of the frame that we brazed up. The ignition key hole was also welded up as i do not like the keys on the side. This scooter may not be to the liking of the puritans as i will be making lots of small modifications

Old Skool Stage 4 175

I have been buying lots of new parts for the engine. The plan is to build the most reliable but a little faster block that i can afford. I did think of buying a new indian 200 engine but as the cheepst one that i could find was £650 and they probably need rebuilding and i'm not a good saver there for i went this way.Engine Spec:

Electronics: BGM 120watt stator with lightened indian shortfin GP flywheel and ducati cdi
Crank: Mazzucchelli GP taper 58mm
Bearins & Seals: Fag+INA with GP flywheel side. Rolf seals and a new mag housing
Gearbox: Italian Li 150
Clutch: ScootRS 46 lightened bell sprocket with surflex plates
Chain & Sprocket: 80 link with ever 15 or 16 front (Not sure yet) and ScootRS chain guides
Cylinder: AF Rayspeed ali stage 4 175 ports polished with asso piston
Carburettor: Dellorto phbh 28mm (not shown)
Exhaust: ScootRS stainless steel
I just have to get a couple of small bits and then i can bulid it!

Casings

The casings have now been cleaned and inspected, one of the barrel stud threads had gone which has been helycoiled. I have also found a snapped stud which holds the mag housing on luckily i managed to get it out without damaging the thread. One of the things i have noticed is that the casings were fitted with Russian bearings, seems a bit odd maybe this is common on Spanish lambrettas, these will all be replaced anyhow along with a new mag housing as there is a crack running around the circlip slot.

Start And Stop

I should have got on with this blog ages ago but with the bad winter and the problems with my p2 its just not happend. O well this is where i am with the lammy
As you can see i have got on stripping her down and have also striped the engine ( sorry some of the pix are off my phone) . The idea that the scooter had only done a 1000k was wrong, more like 10.000k by the state of the engine so i have decided to replace a lot of it, also i have bust the headset trying to free up the gear shaft though this wasn't just my fault as there was already a crack on it

New Arrival

I have now got my spanish beauty, as you can see theres a lot to do but the frame is solid and the speedo reads just under 1000k and it looks like its got its first set of tyres on, the engine does not run as there is no spark but it has good compression. I will not be starting the restoration until the sportique (vbb-vespa.blogspot.com) is done and i have still got some issues with the p2 (vespapirate.blogspot.com). I have got a new toolbox door off ebay as the original one has nearly rusted away, which is weird as the rest of the scooter has only surface rust.

New Project

This will be my new project in time, i'm working on getting this Spanish Serveta li 150 by the end of the year if all go's to plan
