I sleeved both of my cylinders and am in the process of installing them on the sled. I honed them both to within .0029-.0032" of clearance. They are slide through without the rings, but once I put the rings on the pistons, they are pretty tight. I just found my manual, and it says .0037-.0059". Do I need to hone the cylinders some more or am I safe where I am at?

I'm with Ron. Check ring end gap.

I am just within tolerance for the end gap. The manual says .008" - .033", I am at .009"-.010". I want a tight engine, but not one that cold seizes. Do you guys think I need to open it up with the hone a little bit?

Argh, that's what i thought. I believe my hone is a 280 hone, how long is it gonna take to take another .002" off of it?

Shouldnt take long, but check often. If you have the manual, it says how to check. Hone with oil as well, not dry, and wash well when done

If it were mine i'd get a few more thousands for clearance. If it ever gets hot (lack of snow maybe hard pack conditions), you'll want the clearance so the rings don't bind and catch the port. Know what I mean?? I don't know what the piston clearance should be but I'd file the rings for more clearance.
