motor apart, putting back together, help.

Post by desmarat »

Okay, so i have to put the motor back together and i am thinking that i will have a hard time fitting the pistons back into the block. The rings are going to need to be compressed or pushed close to fit. Anyone have any ideas on this or ways to make this process easier and/or more efficient? thanks.

There's no much magic here. Most often you can just put the pistons back while holding the rings tight with your finger tips. You can also try some smart hack, for example using thin transparent plastic film that you can wrap tight around the piston, put it in and take it out. There are also tools for that, or you can search for other hacks that might help the job.

You can put the outer two pistons into the bore before they are installed on the rods...just make sure the inner piston pin clips are installed. This way you only have to awkwardly feed the inner piston/ring assy into the bores as you slide the bores down. Once the cyl block is on the inner two you can install 1, 4 poiston pins and outer pin clips

How I do it anyway.

So, i got her back together and rode around for a day. About an hour into the ride i went back to my house and at idle the valve cover gasket blew and sprayed oil all over the garage! any one know where i can get one? The only ones i can find are on ebay and come from the UK. anyone know any good site that sells them for a good price, or anyone have one they want to sell?
