Can anyone tell me from this picture what kind of cylinder I have?

 

ZEL stands for Zodiac Enterprises Limited. ZEL was an agent for Custom Chrome to purchase and manufacture products in Taiwan. The agreement provided that Zodiac supply Custom Chrome with products that met certain specifications designated by the Company and, when necessary, provide the tooling necessary to manufacture such products.

Crude and cheap cylinders. Don't believe they are still being produced though.

 

Crude and cheap?!? Bugger!

The engine is a 1983 FXWG Shovel. It's a stroker. As near as I can figure, it's 1/4". It was actually a runner with less than 2k miles when I got it so I didn't worry too much about the details. The hone pattern is still visible inside the cylinders but I'll probably mic them as they come back from the coater. I'll also check the stroke after setting the jugs.

 

We used to complain about Dixie and Superior parts (which were japanese aftermarket) in the 60s and 70 and they actually turned out to be be good quality aftermarket.

Maybe a case can be made for Tawainese, but if you look at V-Twin parts (aka Tawain Ted), quality control and proper fitment is an issue that still exists.

 

They look good all dressed up with powder coating and a soda-blasted head on top.

 

Very interesting & cool!

 

So, have you figured out the bore and stroke yet? I saw you posted in another thread a +.030" piston which should Put you at 3.528 with the following link you can see what the oem specs for rings and clearances are.

I figured out the bore. Well, kind of. I dropped the jugs off at the local machine shop and asked him to mic the bore. He called me back with 3.657". That's a 3-5/8 plus 0.032" so I concluded that it's a big-bore with 030 over.

I'm not going to try to check the stroke until I torque the cylinders back on. Since I'm not doing anything that will be affected by the stroke, I'll just enjoy the surprise.

 

Nice... If it is indeed stroked your looking at a 94" Shovel. You can get some real good power there....

 

Good information - but are you saying the measurements are off by .002 and you can round off, or do you think the cylinders are worn by .002? Are you going to go to +.040?
