robert.b.west Posted May 3, 2011 Report Share Posted May 3, 2011 Here is a little background first. I went riding over the weekend and rode all day at Silver Lake. After about a 30 min hard ride, wot in 6th. I heard the top end go. This is only my third weekend on this motor. Well after taking out the plugs I must have developed an air leak (one was chocolate the other was white). I have done plug chops on both sides before and jetting seemed good. I took the head off the piston came apart on the intake side. The only thing that looks damaged is the piston and the dome. Ok now to get to my actual question. I have slight wear marks that you cant feel but you cant see the cross hatching from the hone. Should I be running a hone through it. If so which one? I was looking at getting a ball hone from mcmaster or borrowing one from one of the mechanics at work. I can probably post pictures of the cylinders later. I just hope these wear marks are too much and I would need to get it re-plated. Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted May 3, 2011 Report Share Posted May 3, 2011 I know some guys have ran NiCaSil cylinders with the plating MISSING,,about a nickel sized patch. The thing is though,it was BELOW the exhaust port. Now,if you are like me, you just couldn't handle knowing your engine was being ran in that kinda shape...even IF it has been done before,with success. That stuff is TOUGH. That being said,i'd probably call whoever you bought the cyl from and see what they recommend just to be safe. Quote Link to comment Share on other sites More sharing options...
robert.b.west Posted May 3, 2011 Author Report Share Posted May 3, 2011 This is my first time dealing with NiCaSil so I don't really know what it looks like when it is damaged but my guess would be it is not. It just looks like vertical wear marks on the both cylinders. Very light cant even feel them. There is just no hatching in the vertical marks. Not even sure if I should be running with them. I will post pictures and get your guys thoughts. Thanks Quote Link to comment Share on other sites More sharing options...
BANSHEE HP Posted May 3, 2011 Report Share Posted May 3, 2011 you have to use a diamond hone on nikasil cylinders. a ball hone or hone for steel sleeves will damage the nikasil. Quote Link to comment Share on other sites More sharing options...

Thanks, I guess that is why I ask questions. I did not know that. Quote Link to comment Share on other sites More sharing options...
