Motorcycle and ATV Cylinder Hone Instructions – Flex-Hone
Hi, I’m Eric with Rocky Mountain ATV/MC.com And today I’m going to show you how to hone a cylinder using a flex hone. We’re going to need a drill, a flex hone, a cleaning brush and flex hone oil. Rocky Mountain carries flex hones specific for your machine. The Flex Hone tool is perfect for de-burring and de-glazing cylinder walls. Refer to your owner’s manual for recommended honing instructions and intervals. You can use them on both steel and nicasil plated cylinders. On the nicasil you need to make sure and be really careful. The goal is to simply remove the glaze
and the carbon without damaging the plating. To do this make sure you use plenty of Flex Hone Oil and minimal time honing the cylinder. To start with we’re going to apply the flex hone oil to the flex hone. We want to make sure we get plenty on the hone as well as the cylinder. The Flex Hone needs to be rotating when you put it in the cylinder to start with. It’s a slow spin, you only want between five and twelve hundred RPM’s. Don’t use air tools. You want to stroke it quickly. The goal is a 45 degree cross hatch. You only want to do it long enough so
that you’re de-burring the cylinder. Between 5 and 20 seconds is usually enough. Now that we’re done honing we need to clean out the cylinder using hot water and soap. We’re also using the Flex Hone Brush.
This brush looks big but it will actually work on many different sized cylinders. Once we get it all cleaned out and rinsed off we’re are going to dry it. Then we’ll apply a light coat of oil to prevent oxidation. This is what your cylinder should look like. It has a nice 45 degree angle cross hatch to it The cross hatch allows your new rings to seat better. It also helps with oil lubrication
