while riding the bike just stopped, no wierd noises, just stopped running. stroking the kick-start is too easy, like there is no compression. I removed the valve inspection cover and they move as they should. i removed the side cover and noted that all gears are rotating, so the T-chain is ok. i pulled the spark plug and the piston moves up and down smoothly. I ordered a compression tester kit, and a boroscope (to see inside the combustion chamber through the spark plug hole) but they won't be in till the Snap-On tool guy delivers them in a couple of weeks. In the mean time does anyone have any suggestions as to new ideas or directions to pursue in diagnosing this issue? (FYI: the XR250R is a 4-stroke dirtbike)
