Bike damage due to assembly error
It turns out that the failure of the control arm that
supports the rear diff was caused by the shearing of a 14mm bolt
that holds the control arm onto the frame. The bolt failed because
a support bush had been left off when the bike was assembled at the
factory. When the bolt failed the control arm moved outwards and
forward, nocking my foot off the beg. The the diff collapsed
forward letting the drive shaft hit the swing arm. As soon as it
happened I grabbed the clutch and pulled to the side of the track.
I didn’t brake as I was unsure what had happened. I just coasted to
a stop, all the time the drive shaft was destroying itself and the
swing arm. I have included some photos of the damage. As there is
no such thing as spare parts for an MGS01 I was faced with a real
dilemma . I called my dad, who is a great backyard engineer. He
reckoned he could fix it & 2 days later and the bike was back
together. I have run it on the rollers and it all seems fine. I
guess I won’t really know until we get to the
track.
