Hi there, im new to this forum but have a passion for these little 400s.
Ive recently bought my 2nd nc23 aero.
The other day she just went bang. Now theres a huge hole in the crank cases, metal flew around the the bottom end... essentially shes gone and needs a new motor .
Couple of questions really.
1 - anyone know where I could find a replacement motor? Im hoping theres some bike breakers other than me on here.
2 - anyone have any idea of the compatibility of say an 88 nc23 internals, if they'll fit into the block?

Im at a bit of a loss as all of my local breakers have never heard of the aero
Guess its my fault for not buying a std 23 or a 29
Any help will be greatly appreciated. Thanks in advance
Joe.
