Dirty Scooters - Lambretta Li 150 series 2 restore and 64 GL malossi 221

this blog is a record of my scooter projects. The Dirty Rocket is finished for now, and I am about to begin restoring a '58 Lambretta Li150 series 2. The Dirty rocket started out as an attempt to build my ideal scooter from a rusted bare heap for as little money as possible. (The frame is a '57 VNA) now a 64 GL frame.

- THE DIRTY LIE -



While the bench is still warm from the 'dirty rocket project' I have gone and started another one.
After procuring and attaching EVERY single part of the malossi 221 px engined '63 GL, I have decided to have a crack at an original restore. This time it's a LAMBRETTA.
Yep, I've crossed the floor.
This time the scooter is nearly complete, so each time I need a new part I will at least have the old/worn/broken one to refer to.

More later when I come to grips with what I have done.

The bike will be called the 'Dirty Lie'. Built by dirty derek.... Li model, and the whole process of aquiring parts will involve many a little white lie to my wife. I already said I got it for nothing.

Two horses with one stone

I got a bee in my bonnet and pulled off my sito (2500kms),reshaped the
stub hole and replaced the clamp from an old stock one.
I formed some flashing, smeared it with Dirko (red goo) and banged it on.
It really feels like I am getting more horses in the mid range and the
vibrations are all but gone. (well, relatively anyway).

The malossi stub was in a terrible state, but considering it has been
rubbed approximately....20,571,428 times I think I'm lucky to seal it
at all.

Alltogether a great result. (I never considered the loose stub to be the cause of some of my vibrations).

If you look at the picture I have drawn a green line to indicate where i think the power curve might be now. It's only guess work. It doesn't look much diffrent but averages a horsepower more acrodd th lower and midrange. I haven't tested full throttle yet so I won't get carried away with my green virtual texta.

If I was chasing numbers I would put on the JL pipe I have in the workshop and the curve would resemble the matterhorn. It just seems like a lot of trouble to impress YOU. I had it on the Malossi 210 and it

Taking a peek at the Map - of- Tassie

I'm taking the dirty rocket to Tasmania with the Wife as a pillion as well as all the camping gear.
This trip has symbolically represented the 'goal' of the GL project. A classic scooter with enough grunt to take us both around Tasmania.
I must admit my wife was surprised when i said I had booked the ferry. Even though I have gone on about doing it for a few years, I think she was hoping the dream would fizzle out.
I found this....
Either it will sling across the back of the seat giving my wife lumbar support while the bags hang on the back of the cowls, or I will make a support to put it on the back rack. We'll see when it arrives.

Two fine horses

Quick updates starting today and working back..
Went for a quick blat on the dyno and pulled 2hp more than last time. (pre-28mm carb/reed/ long stroke crank)
I have made a chart showing where the speeds are in different gears.
It shows that, if I get to 8000rpm in 3rd(104 kmh) then shift gears, I will drop to 2000 rpm and 1.75 horsepower. The yellow highlighter shows the climb from hte change to full revs in most gears, showing the need to lose the little dip after 90kmh (4th).

Also..... I had a couple of issues changing gear inermittently. I rebuilt the clutch (cosa) and found a warped top steel plate, damaged tabs on the cork plates and slightly burnt corks. I have yet to settle on what caused this, but it is either failure due to petrol in the oil, naughty riding, or plates put in the wrong order. I used logic to put the plates in last time, and this could have been a bad idea. This time I have gone by the parts picture.
1. slightly thicker plate (small notch on one tab)
2. thick plate with shorter cog tabs.
3. thin
4 thin



Also.. I took the scooter to a music festival (Meredith- drones, dallas crane, Tapes and Tapes, Rose Tattoo, Soundtrack of our lives, New Pornographers, Augie March, etc etc.).
The trip home was in 42 degree heat (109) and there was nothing out of order. Well, the carb did fall off a few times but that was a learning curve on how tight to do up hose clamps in hot weather. The soft rubber simply spat the carb out when done up tight.

A nice cruising speed of 95 was achieved .

Also... the bike ran well three weeks ago at the Mt Beauty 'Mountain Goat rally' . 1000km on a pre-dialled in carb and I was well and truly ready to get it right. Over the windy mountains was great while the top speed was poor on the way home on the wind.
