Recently bought a 94 kx250. Have rode it a couple times, so it had been working and running. The sprocket side chain adjuster bolt snapped while riding. The chain came off and bunched up in between the case and sprocket. Thank God for the case saver. It took awhile, but eventually me and a buddy got it loose. Now that the chain is unstuck we cannot shift the bike period and the front sprocket will not turn. Any hints or helpful tips of things to try or look for instead of me paying a tech to look at the thing.
