Machine Shop Idea: Oil Pump Cover

That looks great so far.    Can't wait to see a finished part.

  It's all good but, isn't Oil Pump Cover rather a misnomer ? Crank end cap maybe?
  Just sayin'

Do you have access to a 3D printer?. My son did all sorts of stuff for me with that equipment.

Hey George, I followed the link, as I scroll down a bit they begin using the term
"Crankcase Cover" for this part,,, item#4 in their diagram.  Yeah ,, I think that name fits a bit better.

Yea but if the name fits then you take all the fun out of it...  If we don't keep things complex then anyone could find it.......

The low-sided '90 I recently bought lost its ignition pick-up plate, trigger and rotor and (of course) their cover (left side).
By mistake I bought the oil pump cap and the big (clutch?) cover for the right side.   My bad (shoulda got a part number from an exploded view before ordering), but unambiguous descriptions would be a "plus".

BTW to add to Randy's observation that covers are not case-savers, the two lower bolts of this cover sheared off and the street ate a bit of case for desert after wiping out the ignition components.  The good news is that crank-end damage was limited to abrasion of the rotor retaining bolt.  A bit more slide would probably have been bad news for the crank end and put this scooter in the "parts bike" zone.

Lesson: case savers are a wise investment.

Anybody got a left cover for sale or trade?

Got the ignition component cover from ebay for $50 after a trip to the local Yam shop confirmed the part number.

Sorry, i missed this, i have some good used covers i sell for 25.00.

That is a very good deal.  Sorry I missed it Randy.  That cover/cap is removed from motors used in the race cars isn't it?

Can you tell me what is "special" about the special fastener shown on the parts exploded view?

On my '90 that fastener sheared/ground off and I'll have to ez-out it. Looking at the relacement hardware I don't see any difference from the other retainers. 

I'm wondering if this a hyper-sensetive spot for the drill dust that will be created in the extraction process.
What's the risk of oil contamination here?

Gracias

[Burns]

EZed it out, no problemo (used left-handed drill bit for the pilot hole);don't see anything special about the fasteners; there's no obvious oil contamination issues.  Picked up the drill dust with a magnet.
over and out.

Hold on a second! I switched my 92 over to blue dots with 14 mm master and with one finger I almost throw myself over the bars. I'm thinking it's almost dangerous how quickly they grab compared to my 89 with stock set up. Am I missing something? Some sort of "magic" Arnie was talking about? I guess this is all about the brakes themselves and not how much clamping force that is required at the lever? Because I don't need much...
      ...and now back to your regular programming.

id say your m/c (as in bore size) is too big, transferring too high volume to the callipers, resulting in movement of the pistons being to fast, smaller m/c = slower calliper pistons = more feel = less dangerous.
but its a balance, you could go for too small m/c and not get enough piston movement and have a constantly long lever, I think there is a ratio for brake cylinders, I don't remember what it is exactly, personally I never had a problem with my original rubber brake hoses, the sponginess gave more feel, brakes are not supposed to be light switches.

well that's my 2 bobs worth, wait a minute, are we in the wrong thread here?
