I have a CR250R 03 i just changed the rings and
Tim,I would look at three main things first. Compression, spark and fuel. Once in awhile us mechanics can get a "hunch" of what's wrong but overlook some common problems. I would invest in a compression tester and a spark tester. Both are fairly cheap and available at any parts store. Simply unscrew spark plug and srew in compression tester and turn starter over. Observe the reading, do this for all cylinders. Then put plugs back in and install spark tester. Turn starter over and observe spark. If you can get your bike started again, check compresiion and spark when your unit fails. This should put you in the right direction. Hope this helps! I’m happy to assist further over the phone at
