There are ring gap alignment pins in the piston ring grooves. The gaps of the rings must align with those pins or the rings can not be compressed enough to slide back into the cylinder bore. Lubricate everything, rings, piston and cylinder with whatever oil you use in your fuel mix before reassembly.

My concern is that if you had broken rings that there is damage to the cylinder walls. It would be rare that the rings would break when the engine is running and there not be damage to the cylinder. Inspect the cylinder walls for gouges. A damaged cylinder will not allow the new rings to seal and you'll be back to square one and will have wasted you money and time buying new piston rings.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
