I just found a buyer, and the problem is this: it seems to not perform well with speeds of 50 or above, though it never had this problem before. Is it the gas, possibly? breaking down in the Hawaiian sun after five months? or the oil? or something with struts/suspension? Mahalo for your time, single lady with no men to help me here

Probably just the tire pressure. a new gas would also help.
