That's a very important thing to point out, DR. You should push forward on the rear wheel to "seat" the snail adjusters tightly against the studs on the swingarm, then tighten the axle nut sufficiently before your son mounts the bike. Then check the chain slack. If the chain is adjusted properly, have your son dismount the motorcycle. Then recheck to see that the snail adjusters are still tightly seated against the studs on the swingarm. Of course, both snail adjusters should be placed on the same setting number. If the snail adjusters are still correct, tighten the rear axle, and lock everything in place.
