Perth County Moto X Savage Customs Sporty Tank

It's the collab you've been waiting for! PCM and Savage Customs have partnered to bring you this piece of art. Our good pal Jamie, over at Savage Customs, has been mixing up Kandy paints and metal flakes. He's laid down this one-off original paint job on a Sporty-style frisco tank. Bolt this onto your current bike to take it up a notch or use this as your starting point for a new project!

What the hell did Jamie do!? 

He went to town as he always does! The tank is black with panels of deep orange/red Kandy with a textured effect. It has pearly peach designs and is trimmed with silver flake pin stripping. The tank has an official collab badge painted in peach at the back. As always, Jamie has finished it all off with a polish that makes the paint look as deep as the Mariana Trench! 

There is only one of these sweet ladies in existence so don't waste too much time thinking about it!!

About the tank

• Low tunnel tank
• 2.4 Gallon
• Mounts easily with front and rear tabs (custom mounting required)
• Has a 3/8" NPT petcock bung on the left side and two 1/4" NPT petcock bungs at rear
• Uses 1982/later screw-in vented gas cap (not included) 
• We always suggest lining a new tank as cheap insurance. The Kreem Lining Kit works great!
• This Universal Mounting Kit makes it easy to install

To mount the tank, set the tank on your bike, loosely thread the rear tank mount to the stock rear tank mounting hole.  Look at the forward mounting tab, It will be over the hole in your frame that you need to open up to slightly bigger than 3/8". Take the tank off the bike, carefully drill your forward mounting tab hole, and bolt the tank on! 

Tank Specs:

• 16" L, 9.25" W, 8" D
• Capacity - Approx. 2.8 gallons+-

**Note:   To prevent spillage from fuel expansion and vibration, do not overfill, fill within about an inch from the filler neck.  We also recommend using T-tape on all plumbing threads. You need to line these tanks. they will rust eventually and then you will be big sad when the gas starts to ruin your sexual 1800$ paint job from the inside out. **

1/8" NPT Steel Bung

TC Bros. 1/8" NPT (National Pipe Thread) bungs are most commonly used for oil tank fittings or when building custom fuel level sight gauges.

Proudly made in the USA from premium American 1018 cold rolled steel for easy welding.

Note: NPT threads are tapered. They are only designed to be used with corresponding NPT threaded fittings or pipe. The tapered design allows the threads to create a leak-proof seal when tightened. They are not to be used with standard bolts or hardware. These bungs install easily by inserting into a 5/8" diameter hole and welding around the 7/8" diameter flange. See photos for all dimensions.

Sold in pairs.

Narrow Sporty Tank

2.1 Gallon Narrow Sportster Style Gas Tank with "Frisco Style" low tunnel to let the tank sit high on the backbone. For years, people have been modifying OEM Harley Davidson Peanut Sportster tanks by cutting them in half, narrowing the tank by removing a section of the middle, and welding everything back together. This look is great, but accomplishing this modification on an OEM tank is very labor-intensive. Fear not, for we have your solution at a great price! This tank is 100% brand new construction and has the same shape that is achieved when you modify/narrow an OEM Harley Sportster tank, but without all the work!

The cap bung is set up high (for max fuel capacity) and is a standard OEM Harley cam lock. You can find a chrome gas cap here and a black gas cap here. The 1/4" NPT petcock bung has been placed on the side near the rear of the tank for maximum fuel usage as well. This tank is the highest quality TIG-welded construction and is pressure tested at the factory before shipping. Please see the photos for dimensions.

Even though these tanks are pressure tested from the factory. We recommend sealing any custom tank with Tank Sealer before painting. Use the Universal Mounting Kit for easy install

Petcock 1/8" NPT

The Prism Supply Co petcocks are guaranteed for life! If you're having an issue with it you can send it back to them and they will rebuild it for no additional cost!

This unique petcock fits direct to a 1/8 BSP thread on your gas tank. This keeps your gas tank looking very clean. It features a 5/16" diameter hose barb on one end and a fuel filter on the other. We recommend using our 1/4" Fuel Line for a snug, leak-proof fit. Rotating the cylindrical piece with the two grooves is how the fuel is toggled on and off. The fuel line does not rotate while toggling the fuel on/off. No reserve. 

2.2 Gal Chopper Gas Tank

The tank uses a screw-in-style gas cap and has threaded ports for 1/4" petcocks.

Even though these tanks are pressure tested from the factory. It is recommended to seal any custom tank with a Kreem Tank Sealer Kit before painting. Also, assure there is no stress on the tank mounting hardware when the tank is mounted.
