In this video, Jonathan describes how he cleaned a Nikasil plated cylinder. Aluminum cylinders are often coated with a harder material such as Nikasil (Nickel Silicon Carbide). Over time, the softer aluminum of the pistons can rub off onto the cylinder. When rebuilding the top-end, this should be cleaned off. This can be done using hydrochloric acid which reacts with aluminum to produce hydrogen gas and aluminum chloride, which washed off with water. Since Nikasil is resistant to corrosion, it is undamaged and protects the cylinder during this process. Here is the chemical reaction: 2 Al (s) + 6 HCl (aq) → 2 AlCl3 (aq) + 3 H2 (g) Resurgence Small Engine Inc. ATV, Snowmachine, Motorcycle, & Outdoor Power Equipment
Hey there, new to the forum. Did some searching before posting but didn't manage to find anything, so forgive me if it's been covered before. I've got a 1990 Quadrunner LT4WD that I got my hands on last year for super cheap (for a reason). It starts and runs great, but the plug is drowned with oil after about a half hour of use (surprisingly next to no smoke though...weird), so I'm going to look at replacing the piston, rings (one of which came out in two pieces) and the cylinder (very little scoring, but definitely saw some bad detonation at some point and needs replacing). The connecting rod thankfully has zero play in it and is silky smooth, so I'm good with how the bottom end sits at this point. Now, a friend has a 2002 Quadrunner 4WD LT-250F that's out of commission due to basically everything other than engine issues, and has been sitting around for a few years. He says that I can just take what I need if they'll work, so I've been looking at the part numbers before we rip on his motor. I see that the part number for the cylinder is the same (11210-19B10-0F0), but the newer models have either "Model K1" or "Model K2" listed as well. Will they work with the older machines or are there a couple little things that just don't let them jive?
Want to replace the Piston / Cylinder assembly on my grandson's 2007 Panther RX-4 110cc. Was going to purchase entire engine. The piston was just stuck in the cylinder. Piston not burned. Rings just slightly rusted to cylinder. Decision is piston size. Ebay has kit. Either 52mm or 54mm but description says kit will fit most 110 cc engines. Measured my piston and cylinder. Digital caliper measures 52.19mm. I need to purchase the correct kit. Also require gasket kit. Input greatly appreciated. Kids want to ride the atv. rickbmac
