Putting in new rings

[101racing]

What do u guys do when u rering the piston. We did scotch brite on 07 ktm 300 cylinder or do you hone with a special stone?

Thanks

I use a 3" ball type hone.

Hope like hell the rings fit!!
My first top end ever .. on my 06 300 really only needed new rings ... unfortunately the rings shipped did not work in the stock piston .. it turned into a little mystery as the part number was correct and the rings inside the package were correct. They just did not like the stock piston ..I had to get a new piston and rings.

Well some people just use scotch bright but really that Nikas lining is supper strong.

To do any realy good just take it to a shop and have them use a diamond hone. It should cost $30 at max then you know the bore is straight and what not.

It's pretty tough. Scotch-Brite ain't gonna touch it. If you have any aluminum on it, from a melt-down, then apply muriatic acid with a Q-tip to remove it. Might have to sand a bit too. When Q-tip is clean you should be set (no more aluminum). Better to get diamond honed, as stated.
