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.

Check and set the ring end gap to spec.

Scotch brite
Did u (gasgas man) get 3 in ball hone for nikasil application and what grit did you use. I dont know if i can get diamond hone or not but i will see what my dad thinks.

101.
The ball hone I used is just a standard 3" version. I don't think they make different grit hones. The idea is just to break the glaze off. Usually, 3 times up and down will do the job. You want a 45 degree cross hatch pattern when you're done. Use WD40 to lube it while honing. |

You wont be able to afford a diamond hone. The 3 ball does nothing on these cylinders because the plating is much too hard. Plus you run the risk of making un-square. Just take it to a machine shop or bike shop.
