Hi1. I have a 1999 Ski Doo MXZ 600 with Rotax Engine. Piston got wiped out by loss of oil. There is aluminum from the piston smeared on the cylinder wall. Are these Rotax Cylinders Boreable? Will honing remove the aluminum from the wiped piston? Not sure what to do. The cylinder doesn't seem gouged just has aluminum from piston on it. I have a honing tool. Should I try honing and replacement pistons or do I need to send out the cylinders for boring and oversized piston?? Thanks. Ken
I'm pretty sure thats a plated cylinder, so you wouldn't want to hone it, but a machine shop should be able to resleeve it for you. The sleeve should be around $100 or so. Labor could vary depending on where it's done.
I rebuilt a buddies 600 last year and was able to remove the aluminum with Muriatic Acid and a cotton swap. I honed both cylinders, new pistons and rings. Got 115 psi out of the cylinders and did over 2000km on the sled last year. Hope that can work for you.
He's right above. Muratic acid will take the aluminum off the cylinder wall. LIGHTLY hone it afterwards and you're all set.
