Piston Pin Clips

[Samuraiace]

I'm trying to find a local place that might sell the Piston pin clips. Anybody pick these up somwhere other than online? I was hoping to get everything together and not have to wait for shipping.

Have you called your local Yamaha dealer with the part number? Good chance that the 22mm or whatever diameter they are clips are used on a bunch of current models and are readily available.

I figured I'll just add the clips to my mikes list, only problem is I'm not sure about the ones they have listed for my year.The one's I pulled out were the regular c clips but the ones listed for my year are different?? Anything I really have to worry about?

As long as your engine serial number starts with 447 you should be fine (basically if it's 1973 or newer).

Yeah that's what I figured I just thought it kinda weird that they were different. Works for me though, Thanks.

A couple of corrections:

1. Motors from 1978 forward were not numbered with the 447 prefix although (in North America at least) they were 447 series motors.

2. Wrist pins from 70-73 were 22 mm. OD. From 1974 forward 20 mm. pins were used.

3. If you're using OE or OE replacement pistons, any clips from 74 forward will work. If you're using aftermarket performance pistons, be aware that clips must fit the grooves in the pistons. Venolia pistons, for example, are grooved for thicker wire than OE clips use, and installing OE clips in them will cause trouble sooner rather than later.

The MikesXS clips are simply a different style than the originals. On the plus side, that added loop on the end makes them much easier to install compared to the original "C" type.
