the crank is fine, just the things attached to it seem to break these days.
things that shear off on my moby:
first it was the av7 cranks, upgraded to the av10
then it was the av7 clutches got a clutch pully, (er3 on the way)
now its the av7 magneto, gonna have to get my cdi working again i guess . naw i'm just gonna replace it with one of the tonnes of av7 mag cover i got round here and hope it lasts anther 4 months
peter er2 down, already!!!! fix b4 sac man, i don't want to see u on a loaner.
