    Question That newb with more questions about honing

    Once again its me asking questions lol. One day hopefully after having done all this I will have input for a future newb ha

    Well since the only local shops wanted 50 to 70 dollars to deglaze a piston hole, and I decided I wanted to try this, I got a stone honer and read up on how to do it yourself. What I read said to use a constant stream of oil and solvent while moving up and down rapidly to get a cross pattern of 400 grit scratches. it said to only do this maybe 7 times. Well afterwards I ended up with this (see pics) They are little scratches from the old rings but arent even deep enough to catch a fingernail on. Are these an issue? Should I keep going till they are gone and see if it is still within tolerances with the new rings?

    I think with all the money I put in this thing I coulda bought a running one! Well, at least I know after all this i am definitely keeping it now, one last piston and a carb rebuild!

    Thanks, this forum rocks

    That's not the hone to use. Most would say to use the ball hone if you do it yourself.

    Only thing I can say is, give it a shot and see what happens.

    Worst thing that happens is you get rapid ring/piston wear or low compression.

    PS: you're supposed to chamfer the port openings to prevent the rings from snagging on them.

    Shoulda used a ball style hone. From what I learned they chamfer the ports automatically and give a good cross hatch pattern for good ring break in. I just did a cylinder on my 780 for the first time and had good results. is where I got my hone and oil. Good prices and fast shipping.
