    how do I put my top end back on?

    never tried this.. and it was easy to get off though. Icannot get the rings to fit up into the cylinder.

    Any tips?

    I agree Chris, have little Chris hold the piston and you can mostly compress each ring with your finger and then use a screwdriver to push it the rest of the way.

    i alway get my little brother over here to help me. he is 11 and has rebuilt 2 older sled engines. he knows how to but the cylinders on without breaking rings. i have him hold the cylinder and push it down lightly as a squeeze the rings in with my fingers or a regular but small screw driver as Liquid-Darkness said.
    down to parts because i no longer have a place to ride trikes.

    make sure you remember those little grooves in the piston ring spaces where the ends of the rings go...

    if your messing the ring up get a new one, most times when ive done it if you get the part in where the ring is split you can push the rest in the your finger nail or a screw driver with a old rag over it....just use alot of motor oil

    great idea indeed. cris if you cant get it on worse comes to worse you can send it up to me. ill do it for free just pay shipping both ways. i have no life till i start work again in a couple weeks. so i can get it done in less than a day and have it going back to ya.
    down to parts because i no longer have a place to ride trikes.

    One way I use when I have no help is -

    Take the cylinder and flip it upside down, placed on a table. Leave one clip in the piston and pull out the pin and take it off the rod. Put the piston skirt side up into the cylinder and work the rings in with the fingers. Because the cylinder is flat on the bench, there is no flopping around or crooked BS. Just slip it in far enough to clear the rings and all you need is fingertips for that, I've never used a screwdriver in a hundred top ends. I usually insert the piston about 1/4" less than where the wristpin hole would be covered. Then I flip it over and slip it on then cases and slide in the wrist pin, pop in the clip and your done. Don't forget the base gasket and put a rag in the crank in case the clip goes flying....

    Eh, the clips would be more trouble than the rings for chris. Chris just wait untill Josh or myself can come help you.
