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.

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.
