Gilardoni Cylinder Skirts

Saturday was a long day in the shop. My Za50 is getting a Gilardoni to replace the Metra80, and I realized that the skirts are different sizes. The Gila and Metra have the same bore, but the Gila's aluminum skirt is a full mm wider than the Metra. I put a wrinkle black finish on my Gila to make it look more like the Metra80, as Travis would describe, the best looking cylinder out there. I disassembled the Za50 transmission and bored the case open. Even though there is a very nice mill in our shop, using a 2 in flap wheel in the drill is hard to beat. I realized my starter cable was beginning to fray at the end where it slips into the lever, so I decided to replace it. A quick trip to the local bike store gave me a nice new housing and barrel ended cable, which I hand filed to the correct size to fit into the two piece starting mechanism. Since Jihee was working on blasting her wheels, I thought I would work my Gila a little, and modified the ports to imitate the Metra80 large ports. Surprisingly, the Gila doesn't have nearly enough meat to open up the ports to Metra size, so I did the best I could leaving enough material to make a good seal. Jihee is also not tall enough to use the blast cabinet, so we had to use some phone books to help.
Finally, a little strike from the Mallet makes sure the motor knows who is boss.

you would think that mustache would be sufficient to let the motor know who's boss

So the side transfers are smaller on the Gila than the Metra? Very interesting... And that's a funny picture of Jihee. She's like the Gary Coleman of your shop, 'cept she's Asian and living.

What are you doing for a carb/intake on this setup? I just got my Gila last week and I'm contemplating which route to go.

Where did you find intact phone books? I thought you tore those things up sight out of habit???
