Hi just bought a 2007 c90 Jackal with 6000 miles. Just had it in the shop today for an all around service and everything looks good with the exception of a small axle leak on the right side so new mission is to find out what kind of axle would be on her. I have seen mentioned a mustang rear end but is there a way to confirm and if so how or does anyone know of a place online to find this information? So far I really like the trike and have owned a 2006 c90 2 wheel and it has been a good bike. Any help on the axle would be greatly appreciated, stay safe.
