wanted - moto giro bike

I just bought a 1957 Gilera 150 Sport, apparently imported from Italy to North America a long time ago and sitting, not running, in collections for decades, first for a long time in Texas, then the last several years hidden away here in Calgary Alberta of all places. I am picking it up tomorrow, will post a few photos when I get it home.

Looks pretty original, at least comparing it to photos I have seen of original bikes. I could really use a manual if anyone knows a source?

No key, so need ignition switch and key. The parts hunt is now starting, I need the basics like speedo cable, brake and clutch and throttle cables, clutch plates, carb rebuild bits, brake shoes, ignition parts, rubber bits, wheel bearings, steering stem bearings, bushes or bearings for the swing arm, chain and sprockets, for simple refresh. Battery and new tires and tubes as well, don't know if the wheels/spokes are useable or not.

No idea as to engine or trans mechnical condition yet. The specifications I found online say 7.2 horsepower and 100 kph top speed from the very stylish looking single...... was minus 27 Celsius when i went to view the bike, in an unheated storage place, rather poorly lit as well. But, where the heck am I likely to find another 1957 Gilera 150 Sport outside of Italy so I have taken the leap. What can possibly go wrong..... ;):eek::ROFLMAO:

I’m green with envy. I reckon the cute girl serving at my local bottleshop would love seeing that pull up. She’s one of those rockabilly types, with the fringe and Tatts.

I digress, fill her up with fuel, throw a lawnmower carb at it, and kick it in the guts. Let’s see what it does.
 
Is that the one that has a 4-stroke engine that looks like a 2-stroke?
A mate of mine had one of those a few years back. I think he said the model was '150 Sport Arcore'.
I saw him on a club ride the other day but didn't ask him about the Gilera, so I dunno if he still has it. Even if he doesn't, he may still have some tech info. I could put you in touch with him if you like. He's an engineer so should be reasonably competent with the technical stuff.
 
more photos. Appreciate the initial advice and info. Any more info and tech resources greatly welcome as well.

Before disassembly, I am going to thaw it out in my heated garage, change the oil, put a new battery in it, hot wire the ignition (no key) and see if it has spark and compression

First question, the speedo meter shows 35495. On these speedos is that an actual 35,495 kms or is that 3,549.5?

That's 39 thousand km.
Ignition key is probably standard like the BMW nail.
Put petrol in it, fresh oil, make a couple of cables and ride it. You may not need a battery.
Why do you want to dismantle such a nice little machine?

this time I agree with you. Fresh oil, a battery, some fuel, hot wire the ignition, and see if it will start, then assess from there.

Definitley new tubes and tires, all cables, maybe brake shoes and wheel bearings. Would be very very cool if then could be run basically "as found". This may be the first old bike I have brought home that I might leave in original patina, although it will be tough to resist polishing those gorgeous engine cases. Not sure what to do with the peculia original " cast" muffler though
 
engine turns over freely, front brake brakes, rear brake does not, clutch lever pull is heavier than a Laverda triple's, seems to shift gears, started my parts search by looking for 2.50 x 19 inch tires, lots for dirt bikes, closest fit for street purpose may be Heidenau K34 in 2.75 x 19 if I can find someone to sell me a pair...... The existing Pirelli tires are so rotten they are disintegrating off the rims just from having been rolled a short distance. Also off to try and find some online Gilera resources, what are the odds there may be something like our Laverda forum for 1950's Gilera.....;)
 
Woo Hoo!
Many classic British bikes run 19" tyres, maybe ask a local Velocette owner where they get tyres from?

What's all that white stuff on the ground and everywhere else? :unsure:

cheers,

Get quality inner tubes as well. I use motocross or enduro tubes now. 3mm rubber.
There's a shop in Italy, but that's a long way from you. Italian Classic Tyres. Excellent service.

Clutch pull likely cable related.
