Ok I'm all over the place with this post so bare with me. I've looked around this forum and all over so if you know of any articles/forums that could help and haven't really found too much, so please direct me to them if they're around.
I have a 2010 rzr 800. A few months ago I was having a backfiring issue due to rusted and deteriorated exhaust connects, I think in turn that put some wear on my head gasket and caused it to start slightly smoking, but I am also getting some very hot engine exhaust temps, I mean like the exhaust would glow red after maybe 1-2 miles of leisure riding but I didn't ride it much after the heating...Could be from the blown head gasket? Bad rockers? any input is welcome
I am changing the head gasket and since the weather is getting cold I decided to tear the top end down and replace and repair anything that was needed.
Everything came apart great with no major build up on the valves or anything and nothing that looked to have gained any problems from the exhaust heating. As I got down to the cylinder and the pistons I noticed that both of the pistons have significant identical abrasions on the intake sides on them. The cylinder also has the rubbing wear on the inside of it.
I can still see the factory cross hatch marks very slightly through the rubbing in the cylinder though I'll probably send it off to machine and plate while I have the winter months and I'm going to replace the pistons as well.
The crankshaft arms have very little play when centered, but show no resistance when moving the way they should.
My may point of writing this is to see if anyone knows the main cause of the pistons and cylinder wear or know of the reasons the exhaust could have been heating up so much?
I'm not mechanically inclined enough to get down into the bottom end of the motor and mess with it so if it a crankshaft or balancer issue I'll most likely pull the motor and send it away.
Thanks for any input.
