Part: Piston Pin with C-Style Clips for Honda CB350 / CL350 Scrambler / SL350 Motorcycles
Why You Need This Part: If your engine is apart for an overhaul take a good look at the piston pins (also known as wrist pins and gudgeon pins) that came out of your pistons. Even if your engine's cylinders measure within factory service limits, and do not need to be bored oversize so you can reuse the old pistons (if those are in good condition of-course) the piston pins more than likely have taken a beating with grooves worn in them from the connecting rod. Unless the surface finish of your wrist pins is perfectly smooth they should be changed out during your rebuild. Our replacement wrist pins are designed for the original cast pistons found in the Honda CB350 / CL350 Scrambler / SL350 engine and will work with NOS Honda and our very own CMC "Pulsar" oversize pistons as well.
We have found that even though many wrist pins on the market do have the same diameter they are too short in length. This will cause the pin to float in the piston, which will lead the retaining clips to hammer loose causing serious engine damage. This will not be a problem with our CMC piston pin, as it will fit perfectly inside your piston without any additional give. The piston pins come with a new pair of "C" style retaining clips, which should be changed out every time they are removed.
Each pin and clip kit is sold individually. One set need per piston, two sets per engine. Make sure to pick up a fresh pair of piston rings and an overhaul gasket kit to finish the rebuild right.
Installation Tip: Install one clip on each piston on the side that faces the cam chain before installing the piston on the connecting rod. Oil the piston and wrist pin well upon assembly. Be very careful not to drop the second clip in the engine during installation. Also make sure that the ends of the clip face 180 degrees away from the notch in the piston.
