So was reading and came across a read that said you could use the Fram CH6009 on a cb500 . Anyone confirm this. Nice they are available local and cheap. I recall some chrime spin on filters I had for a cb750f that were simple spin ons but had problems with horrible leaks so I canned them. Trying to figure out whats causing my trans to almost not shift after its heats up . Shifts perfect and then 30 mins riding .....extremely hard shifting. Switching to 20-50 and rechecking my timing today. May have cooked oil from an hot engine...Shooting it with a temp gun today.
