Vintage Dirt Bike Q & A

Put my mt250 engine back together again for the second time. I ended up with a leftover what looks like the end of the clutch lifter rod. Its not the clutch lifter rod as its not broken and it works fine. I couldnt find it anywhere in the parts fiche or shop manual so I have just come to the conclusion thats if it did come from my motor its not going back in as I dont know where it goes. Its about an inch long and the same size around as the clutch lifter rod with one groove cut into it. Anyone know what it is?

Part #3 below looks similar, but all of yours are probably present and accounted for.

Yes it looks about like that but I dont have an mtcylinder its from a cr so I dont think I have those on my cylinder. Are they in the fins to keep vibrations down im not sure what/where they are. I am going to take it to the mechanic I know and see if he recognizes it. Its free so nothing to lose but time.
