Hello,
I have a 1995 xr250r thats getting practically a new top end. new piston and rings, cylinder honed, new valves, valve keepers, cam chain, and like one or two more things, and I don't have any experience with breaking in engines, so I was wondering if I could get your opinions on how I should break it in?

Thanks.

Cylinder honed on a 95?  What is the clearance like with a stock piston which is apparently what you are going to use?  That's an iron sleeve, not a coated one, they wear.  Since you are there now is the time for big bore, you won't regret the bump in power and bottom end. ;)
