Happy Fathers Day!!!!!!Thanx for the compliments gentlemen-Chuckorlando-It's not babble!!! My "different type of buggy" uses similar links as described (mini sprint)
I'm convinced the abuse comes from the constant up/down shifting at the wrong speeds!! when the kid's downshift at WOT to the next lower gear (intentional or not) there's a huge load applied to the swingarm. I've watched the engines torque want to twist/roll-over sideways in the swingarm.
The major issue is driving/jumping beyond the design intent-just pushing it to failure due to excessive abuse, but then that's why we play in these toys! I'll keep improving the structure till I get it right.
kliff- The tensioner is still working like it was intended. My only complaint-there's alot of noise(snapping/slapping) associated with it steadily moving the springs
