As per your config, I guess you are referring to the VPN connectivity with Peer IP 166.149.125.81.
If yes than you have missed the other subnets of main site in the ACL outside_cryptomap_1
which have been mapped in the VPN with this Peer.
object-group network DM_INLINE_NETWORK_2
under this statement match the network-object with the subnets at main site that needs communication with the subnet 192.168.90.x/24 at remote site (same as you have done for 192.168.0.0/24 subnet)and vice versa.
