CYLINDER CLEANUP

<< < (2/3) > >>

monster malibu:
Well I cleaned my cylinder and the aluminum trails are gone, and so is some of the coating. There are actually wear marks in the cylinder were the aluminum trails were, so I need to find a place to have my cylinder recoated. What do you guys recommend? I was thinking about calling LA SLEEVE, or US CHROME. Should I send the new piston with the cylinder when it gets replated?

hughes:

What type of coating should be applied to my cylinder?

Hillclimb#42:
 Electro fuse or its also called Nicacell. Sry, not sure about spelling. Anyone rebuilding motors or re-sleeving will know exactly what you need. They hone the cylinder and then fill the cylinder back to oem spec with the electrofuse coating. You really only need to take the cylinder to them. Top end kit is pretty cheap and several local people will probably be able to help you out. The damage is common to cylinder and will be fine. You want that coating. It is very resistant to wear. The piston being a softer aluminum usually takes more damage than the cylinder. The thing that you may shop for is the turn-around. Some places can get it done weeks before others.
 When that comes back, coat bearings and cylinder in 2-stroke oil before assembly. Take the new piston all the way down to get the jug on it. Don't twist the jug to get it on the piston. It helps to have an extra helper hold jug while youy keep the rings tight. Once the rings are in the cylinder, you can use the kicker to get the piston into it farther and then its time to get it all back together. Its also good idea to torque all motor bolts and re-torque after a good warm-up and cool down cycle. I warm a fresh motor and let it cool a few times, before a break in ride. Then I take it easy for a tank of gas. Let it cool one more time and then give her hell from there on. Good Luck!
