Chain Adjusting question, with pic to explain

[2fastandfurious]

I am having trouble with my 250x. It will not hold the tension in the chain. I ride around for a lil' bit and then it slacks up. Not all the way but too loose to ride. I suspect its the 2 allen wrench bolts. Does anybody know what those are called so I can call honda and get new ones? Also what tool do you use for the gray peice to tighten and lossen it?
Thanks!

loosen the allen bolts then i use channel locks and just rotate the axle carrier towards me to tighten it up when it gets tight enough just tighten the allen bolts and ur set

[jerry-89-250R]

the bolts are called axle pinch bolts, the gray thing is your bearing carrier, sounds like the nut's underneath the swingarm are stripped, you might have too use longer bolts "8mm" and put lock washers and nuts, too keep it tight,
