Nice job. So it's just unscrew and replace ? Looks like it.
Ooh I really like now.
Oh one moment please...while I kick in mr angry negative ********... before someone else does.
Ahh.. cb750 you must live in a bright neck of the crime free woods because a strong grip strolls by and your brand new filter is gone, your oil is on the tarmac, and you're stranded. I hope you have a Nike alarm, or a bike alarm.
Not to mention, a good sized rock and it's right through that tin can bosch instant oil spray painter, and you're stranded on the highway that time.
There is a reason Honda engineers decided in their vast wisdom to encase in strong metal...
( feel the hate, let it flow through you ! )
Gosh I hope no one else posted yet.
ps edit #2: You thought I was done ? Hardly!
Have you done an oil pressure test before and after ? How about a flow test ? Have you checked cooling characterstics ? If you're into early engine damage ignore this.
(hahaha)
Okay now all that is out of the way.
