Was told my rings was prolly burnt up, came back from a ride and it's smoking really bad and burnt about 3 quarts of oil in 4 hours. If it is rings does anyone know how much it will cost to get it fixed. Or does it sound like something else is wrong with it?
Well, if using 3qt of oil in 4 hrs, chances are at one time or another it ran low on oil.
So on a 900, in the frame engine rebuilds(top ends) , while possible are not the way to go imo, for many good engine rebuilding practices/reasons that could fill up another thread.
So now you got the engine out, valve train disassembled, head off, cylinder off. And you're just going to change the rings???
Why not go to the next step and split the cases to check on your lower end that might have been(probably) run low on oil?
Also check and measure every engine spec, and R&R as needed.
I could not see doing it any other way myself...
As I tell all my companies service techs, (some more than others)... Always time to do it twice, never time to do it right...
