Valvetrain noise on these bikes is noticable- they are not Honda's. Even in the 60-70s they were somewhat noisy. The oil leak shou;ld be an easy fix tho. Like said- warranty 24/unl mi. Ride it ! If it should take a ***** on you - got docs- fix or replace. Gonna be a while - get a loaner till fixxed. Mine has been Honda reliable so far (knock on wood). Good luck & good ridin!!
