550 crankcase oil guide
« on: July 08, 2023, 08:15:03 PM »
Reassembling a motor with New(er-ish) stuff.  And the plastic oil guide screwed onto the lower case half is not new(er-ish)

Still in one piece, but given what happened to an old plastic part before.  I would like to replace it.

Only one hit on ebay.  And of course, weird item N/A in the warehouse.  Where else should I look?

Do you have the part numbers? I don't know the 550 motors to look up the part numbers.

What is the florescent green slime on the front of the cases?

Interesting looking front end on the bike, leading link front end? Racing side hack rig?

Went ahead and mated the cases.  A successful joining it was.

I'd have to dig through the fiche to get the part number again.

The green slime is actually a gear tie (rubber coated wire) - i keep a couple in the tool box cause they really come in handy.  In this instance, i used it to protect the rods from the case half during handling.

Ended up using some 045 tig welding stick to hold the rods up when lowering the top half on.

And yeah, thats my race bike.  With a bastardization of an earles/greaves/LL fork.  Haven't made a hack for the monkey yet.
I'm growing frustrated with trying to get the spring rate and preload dialed in.  First the ryde fx were too much, then the air shocks had no spring to return, now i have one of those blasted cafe racer shocks on there with the air assist opposite.

One of those rfy shocks spontaneously unthreaded itself during my initial installation.  Kinda spooky.

Now that you mention it.  Guess i could've assembled the primary/starter gear through the oil pan cavity.

Oh well.  Everything works so I didn't do it all wrong 🤷‍♂️

Big thing is getting the bearing dowels located and thats way easier in top half.
You just leave the starter gear and cush drivewith primary chain round it lerhed on the gears then fit shaft

Those bearing dowels were a chore.

Now onto even more chores!  Like cam timing and valve lift clearancing!
