Some how the circlip got past the rag...any ideas on how to fish it out? Do I have to split the case?

Try the magnetic pick up tool first.
If that dosn't work tip the motor over and try flushing with diesel and air.

Try putting a little grease on the crank and slowly turn the engine over. Sometimes the clip will stick to the grease. Good luck.

That happened to me when rebuilding a friends quad (yfz) and I got it out by turning the motor upside down and shaking it for about 5 minutes

Same happened to me with a shim. I took the engine out of the frame, and took the ignition cover off to start the disassembly, and I saw the shim laying in the bottom, so I fished it out with a magnet. YAY!

The way I go when rebuilding a motor, wether it be 2-stroke or 4-stroke ( I learned this on a two stroke) is to take a couple rags and shove them into the opening so you KNOW that nothing can get in there.

When I say shove, I dont mean cram rags down to the bottom of the cases, I'm just saying put some rags in the openings.

That's a good point. Removing the flywheel cover does get you a look at the low point of the sump (the sump screen is visible through a port behind the flywheel.)

Another thing along the lines of greasing the crank is to firmly tie a bit of rag to a length of wire, grease it, and pull it through under the crank. If it doesn't surface, check the screen area again.

If you did not actually see where it went, the possibilities are endless. I've seen circlips fly 20 feet easily. I know one guy who fished around in his engine for hours, and finally pulled it out of the frame. The clip was sitting on his glide plate. :moon:

I had this happen to one of my old two strokers. We ended up hanging it from a tree (literally) from the back tire cause we didn't want to unmount the motor. A little shaking and a magnetic pen finally did the trick. I'll have to see if I can find the pic of it. But either way, flipping the bike up on end was what worked for us. Good luck.
