Part: "Pulsar" Series Oversize Piston Kit for Honda CB360 / CL360 Scrambler/ CJ360 Motorcycles - TWO PISTONS ARE IN THE KIT

Why You Need This: Engine rebuilds are par for course when racking up the miles on your Honda CB360 / CL360 / CJ360's engine. Cylinders may have to be bored oversized due to wear and measuring outside the usable service limits. If this type of service is needed, the old pistons, rings, wrist pin and retaining clips need to be replaced with a new parts to match the new oversize cylinder bore.

For years now, original Honda factory oversized pistons have been obsolete for the Honda CB360 / CL360 / CJ360, but this is no reason to loose hope. We have worked long and hard here at Common Motor Collective to bring you a top quality oversized piston kit. The "Pulsar" series pistons are derived from the original ART cast aluminum pistons used new from Honda. However, with the advances in modern manufacturing processes, we have added a number of performance improvements to the original designs.

  • Each "Pulsar" piston is made from pressure cast aluminum and CNC finished machined.
  • Piston skirts feature a MoS2 (molybdenum di-sulfide) dry film lubricant anti-friction coating to applied to the aluminum surface to reduce wear and scuffing.
  • Piston crown and the top ring groove have a high temperature hard anodizaton applied to the surfaces to increase overall piston durability and thermal transfer (important in an air cooled engine) as well as preventing the top ring from micro welding (aka getting "stuck") into the ring groove.

Speaking of rings, the "Pulsar" series pistons include modern piston rings to improve sealing, ease of install and ensure long service life. Each ring set includes:

  • The top ring (silver) is forged steel with a gas nitride coating. This is a hard coating process that permeates all surfaces of the ring, increasing wear resistance and reducing the coefficient of friction on the cylinder walls.
  • Steel phosphate coated 2nd ring (black).
  • A three piece oil ring, which makes easy installation on the piston and into the cylinder assembly (A LOT easier than cast iron one piece oil rings). Top and bottom rails of the oil ring are also gas nitirde coated.

Additionally the "Pulsar" series pistons kits also include correct length writs pins (gudgeon pin) and the proper "C" style retaining clips, for correct fit with minimal pin slop.

"Pulsar" series Pistons are available in the the following oversize options:

  • 0.5 mm Oversize - #4304
  • 1.0 mm Oversize - #4305

This "Pulsar" Series piston kit contain TWO PISTONS, one kit will rebuild one engine

Get the rebuild done right with our gasket kit, cam chain, oil seals and a new cam chain tensioner

Installation Tip: Install piston rings with the marked side facing up toward the crown. On the 3 piece oil rings, the wavy ring goes on first and then is sandwiched by the thin rails on the top and bottom. The "C" style wrist pin clip is installed with the open end opposite from the notch in the side of the piston. Ensure that the clip seats fully in the circumference of the groove as sometimes the end of the clip can catch and not fully engage. Put the clips on the inner side of each piston (side closest to the cam chain) before placing the pistons on the connecting rods. Thus install the wrist pin from the side of each piston facing away from the cam chain. Put some rags in the engine case and cam chain hole so you do not drop the wrist pin clip in the bottom of the engine case! Check small end of the connecting rod inner diameter for wear beyond service limit. Install the pistons with the arrow facing toward the front of the engine. Make sure to lubricate the pistons and cylinders with motor oil before installation.

Cylinders must be bored oversize by an engine machine shop, and it is best to have the new pistons available to the machinist when dropping the cylinders off for work. We recommend a 0.001" to 0.0015" piston to cylinder wall clearance when over boring cylinders. Wash newly machined cylinders with hot water and dish detergent. Wipe the cylinders clean with a white cloth, when the cloth shows no dark residue the cylinders are ready for reassembly.
