just went down to local honda dealer and ordered new rings, boys in workshop said " do u have expander rings for it", i said yeah for the bottom ring, he said dont put it back on when you replace the rings, they cause more problems than they are worth. i said whys that, he said excessive rings wear and they can score the * out of you bore.
so now i'm thinking do i put them back on or leave it>??? whats your response,

the black spring like piece between the bottom ring, and the piston. i would put it in, since it expands the ring. its there for a reason.

yeah thanks guys, will do and plus if i didnt what would really be the point of putting bottom rings in, cos they would stick out enough

in this picture is the very innermost ring the expander ring? I've seen one of those w/ every ring set I worked with but never used it.

this issue is least on my mind now!
as i was putting the rings on the piston, and putting the piston on to the crank, i slid the guiden pin into its hole, i had a clothe securing the crankhousing so the little pins would fall down into the crank housing, i did one side fine, wen to do the other, the pin popped out of my pliers and fell through the small gap in the clothe down into the crank housing! i have taken the engine out and tried shaking it out, but i cant hear anything!
what i do? do i need to take the whole crankhousing out? help!!!

u took the whole engine out? as in case out of swingarm?
I had something similar happen when a piece of the stock piston broke off and fell down in there, siezed my crank to only move a certain rotation. I dumped all liquids and flipped it upside down and played with the crank while shaking it and eventually the piece(s) fell out and i had this same crank work for the entire time i rode the spree.
try that and see what happens.

yeah it took the whole engine out, iv been shaken and stuff i really cant get it out, must be all that oil i guess, the boys on another post have told me to spray some carb cleaner in there. so il give that a go.
