What I would give for the skills (and equipment!) you are putting to use here. Seriously, great ideas and designs. This is already my favorite project to watch.

Great work indeed...  One concern, how are you going to change the filter without getting oil everywhere?

my guess is removing the two bolts holding it in, but I'll let him speak on that!

i thought about that too, but it just seems like quite an inconvenience, and what if he over tightens the oil filter?  it would be hard to get enough leverage against a free moving adapter.  but his work is quite good, so i'll wait for him to say!

I think he said the lines are flexible, so once the two fasteners are undone, the whole thing can swing and it can be oriented vertical

Hey Hannibal, I have some worthless trivia for you. Something I was watching on History mentioned the P38. The 38 in the P38 designation stood for the number flips on the opener that a soldier would need to make to open a can of C-rats.

Told ya it was worthless ;-)

I already asked him that, he says that yes, the two allen head bolts come out and then with the flexible lines you can swing the hole assembly out from the motor to unscrew the filter.

And if you require a lot of leverage to unscrew your filter you are overtightening it.

true, but sometimes filters have a nice way of getting too tight after heat cycles...  maybe it's due to a cheap rubber sealing o-ring sticking.  either way, he'll have no problems with it, it just like the simplicity of my front mount spin on filter on my 750 :-D

Update- Engineering the front brake setup. I have done many of these, but the stock CB550 legs don't leave too many options.
For safety/rigidity, you need some minimums, and after some extensive mods, I have them.
Plan "A" was caliper mounted aft of the fork tube, but after crunching numbers and a mockup, the jog in the bracket would not be sufficient for safety.
Plan "B" was to run the caliper in front (as is stock) and with this configuration, I have plenty of room.
I did have to machine the forks, as you need certain tolerances for deflection when riding, especially these old forks- the buttons on the carrier need at least .075" clearance etc.
I will take pics when she is done.

When I saw P38 I immediately thought of the twin tail boomed WWII fighter and thought this was going to be one of those cheesy 'theme' builds. I was wrong. There is an envious amount of craftsmanship and engineering going on here. Fantastic stuff.

great work indeed.  hard not to appreciate what you're doing.  i'm very surprised that there are not more questions for you to make us this or that.  surely you have thought about offering some of these items for sale to us 'others'.  whatcha think?

Awesome work!  I am extremely jealous of the tools and machines you have at your disposal.....  Not to mention the skill you have to make the parts you are producing....  Want to make me some motor mounts for my 750????
