Are you sure it's 1/4&quot;? I've looked through the parts book and I am having trouble finding anything that uses that size bolt. If it is 5/16, then it sounds exactly like one of the bolts that holds the shift forks onto the shift rails. Take the bolt and put the head in a box end wrench. If it takes a 7/16 wrench, it is a 1/4&quot; bolt. If it takes a 1/2&quot; wrench then it is a 5/16&quot; bolt.

If it is a bolt from a shift fork, then the harm at this point is minimal, until the other bolt comes loose. Then you'll have trouble shifting into a couple of gears. If the bolt is 1/4&quot;, then I haven't figured out where it came from.
