hay thankx guys for your help..i will try and do my best to fix this problem...
sorry aboout the subject change i'm new to the whole forum thing and have no idea how it all works so from now on i will post my questions in a new topic page..
theres no play up and down but there is side to side,this is sopose to move to the sides,but i don't get how the bottom of the piston broke how it did unless it hit something thats why i thuoght the main bearing was no good.it would be great if i just have to put new piston and rings in.....
maybe when it's fix'd we all could go out riding...
agian i thank you all for the info...

ride safe or at least ride hard...
