Modern Vespa

Thanks CM22! I'm having fun with it.

Ran into an issue. I changed the oil before I started and uugh, it was looking fugly - finely ground metal flakes making the oil look metallic.

So this is after running it up the road (3 miles maybe).

I'm going to pull the clutch and see if it has to do with the 23 tooth DRT clutch gear. Hmmmm. Maybe the three speed transmission gears? Hmmm....
Another mystery...

Put a magnet in the oil to check if its steel or ally (alumin ium). This will help with what to do next.

Excellent, thanks Jack. Should've thought of that!

I just went for a ten mile ride and drained the oil. This time checked it with a magnet. No particles on the magnet.

I'm going to pull the clutch and inspect...


Nothing sticking to the magnet

You're looking for al-loo-MINNY-yum, not steel, so it won't be the clutch. And brass is a different sheen in the oil.

Off the top of my head, I'm not sure what that would be, unless something is rubbing on the case, and I'd think that would be pretty obvious as soon as you kicked it over.

Glad you got the side stand. Looks great!

Thanks SoCalGuy - it's a cool stand!

So I think I figured it out! I noticed some rubbage on the clutch cover, and started going back through the history in my mind.

Seven spring clutch - trimmed cover and tab inside engine case.
Clutch still didn't fit - 1mm spacer (thanks Whodatschrome!)
1mm spacer still not enough, bought 5mm spacer
Never removed the oil trough in the cover - I trimmed it up today.
I pulled and inspected the clutch, plate by plate, all good.

So I think I found it - clutch cover rubbage. I dremelled it down a bit and cleaned it up.

Then disaster struck! I dropped the woodruff key into the engine. And in my haste to get it out I 5 minute epoxy glued a magnet to a coat hanger.. .and promptly lost the magnet. F+@K.

So tomorrow I'm going to pull the engine.

I guess it could be worse, my rear shock mount could've snapped in half!


Old Dremel job. Slight rubbage by the end of the channel

That's better

Oh man Scott - I am laughing - near not at.
When it rains it pours.
That sounds so much like me.
"Wait til the fellas see this trick!"

Have to say - the magnet on a stick sounds perfectly brilliant to me!
So unlucky!
At least you didn't turn it over and trash a gear...

And it's easier to sleep once you have diagnosed the actual root of the issue with the aluminum.
So net net - its a win.

Couple of $.02 things:
You can drop the exhaust, shock bolt, lower the engine, remove the two outside cylinder bolts, pull the cylinder out a bit, and split the cases to search for the magnet and Woodruff key -- vs removing the engine.

Your push pin shows signs of a too-tight clutch cable(?)

If you clipped off the tab in the engine, that channel you dremeled is no longer fed by oil, so no need to be conservative there. Your new clutch (probably) uses another method of lubrication -- the BGM does.

Thanks CM22 for the encouragement!

And thanks R8 for the alternative method and info. I think it got grooved when I was running the 1mm clutch cover spacer. I've got a new one coming anyway....

I chose to pull the engine. I can do it in a half hour, taking my time. I've become quite adept at it.

I turned the engine upside down and plop, the woodruff key hits the floor.

And I think I finally saw the magnet with the cable camera, wedged between two gears. I ran out of time but tomorrow maybe I can extract it without splitting the cases. We'll see...


The little f#&ker

Nice work! Just like a pro! I believe in your magnet retrieval powers!

Thanks man! And guess what? Success! I got the magnet out! Wooohooo!!! Your encouragement in my retrieval powers helped

It was not an easy task.

I spied it with the cable camera after about 20 minutes of looking.
It was nestled in between two gears.
So I tried various implements - no go.
I took miniature needle nose pliers and heated them, then bent them in the vise.
Still no go.
So I got another magnet - and pinched it in the needle nose.
Using the camera, and the pliers holding a magnet, and holding my breath, the clock stopped
Until - click - the magnets stuck together and I gently extracted them.

What an awesome feeling!

Next thing was why the 22tooth clutch gear wasn't working. I left out the woodruff key and tried to install just the clutch. And it wouldn't fit. The gears weren't jiving.

So I measured them...son of a biscuit, the 23 tooth gear is a smaller diameter.

I put the 23 tooth gear in the clutch and a new woodruff key, and it slipped together like butter!

After I did a happy dance and called Chris, I put the engine back in quickly and went for a spin. It's nice to cruise around on the Blue Bomber again.

BTW, Chris offered to come over and help me retrieve it right then and there. Now realize, he's 90 minutes away and it was 6pm. Now THAT'S an amazing friend and all around good dude!


Gotcha!

Different diameters between the 22t &23t DRT clutch gears...

That's awesome, Scott!
Thought magnets repel each other.

How did people survive without them?
Neanderthals.
So awesome.
Can only imagine the moment you finally spied it - you said something out loud - because talking to inanimate objects when you finally solve the unsolvable - deserves comment.

Nice pull.

Thanks R8 & CM22.

Yes, words were said - something like "There you are you little bastard - FINALLY". Then I took a deep breath and did a little jig, and gave thanks to the scooter gods and everything in general!

I went for a 25 mile ride today before the rains came in. I did the normal loop around Florence with a stop at the Port, the beach, and the Jetty overlook. Got a bit of break in for the new piston and cylinder!

And it was super windy, which most people don't enjoy, but in the right context, it can be really fun, and I had a blast bouncing around to the wind gusts

When I got home I promptly drained the oil and it's getting better. Not as much al-u-minium goop in the oil.

Speaking of goop in the tranny oil - does anybody have any trick to rinse out the gear box? Like add a bit of gas or kerosene, run it a mile or two, then drain? Maybe that would clean out the stuff in there a bit quicker?


Crappy picture, but the ocean is out there and the sand was blowing sideways on the beach!

Haven't tried this, but google Marvel Mystery oil. I don't think you need to start the engine. Just kick it to swish it around and drain.

This may sound sacrilegious, but if you want to get those aluminum particles out, run a good detergent (yes, detergent) oil for a hundred miles, then go back to good ol ND 30w. Trust me, it'll clean it out, and won't hurt anything.

Thanks R8 & SCG!

I'm gonna give the detergent oil a try! This is a good tip - thanks again!

Stick with an oil such as detergent type mentioned. Those seals in there may not like some chemical types, wouldn't want to ruin your seals.

great seeing it back on the road.
one of my fave scoots on this forum.

Oh man...I think I got some smoke in my eye...

So I deviated from my "drill no holes" policy, and I'm glad I did...


I just doubled my grocery run capability

Flipping your scoot the bird in gloved fingers is best pic ever! Been there, done that

That dang Woodruff key! I've read about him plenty. Have yet to meet him…. Congrats on the creative relocation.

And B62 gets a handsome chrome accessory!🥳🥳🥳

Taco run impending, methinks….

Looks great! Worth the holes, ok?

Could I get a picture of your leg shield spare tire holder? I'm looking to source one like it. Thanks.

Thanks K32! Taco run for sure! Sure thing garn. i got it from ScooterMercato.

With a tire on it

Side view. I made some rubber gaskets out of an old inner tube to protect the paint.

Other side

Gracias!

The improv gasket is the perfect finishing touch. I have a legshield spare holder for my GL (so 10") but never considered installing it because it would scratch the paint.

Yeah, obvious in hindsight, but I still never thought of it.

I've been breaking in this new Pinasco 177 2-port cylinder and piston. It's been acting like an air leak. It takes a bit to get to idle then wants to die.

I finally got serious about it and messed with jetting, then before pressure testing for an air leak (again) I decided to pop in a different 24/24 carb I have in the wings just in case.

Lol and behold, swapping carbs made an amazing difference. But I think the only difference is the slide. The flat bottom slide is the slide that's on the carb now, whereas the bottom notched slide was on the old carb.

I still need to put the notched slide on the installed carb to prove my theory that the slide was the issue. But regardless, it's running fantastic once again.

Now to start the jetting process - plug chops will commence soon


The slide that (I believe) was the main issue...

I've been riding and watching temps. Shooting for keeping it below 300f.

So that means 120/BE4/130 & 45/120 idle. Keeps the temps below 300f and the plug looks pretty good. More riding is needed though so I'll keep y'all informed.

The main thing I wanted to post is that I got a package from GeekLion the other day. These eyelets are fantastic, and are a great addition to B62! He also sent through a big rubber bung cap to go over the exhaust port. Very cool!

Thanks GL! Much appreciated!


The package I received

Just need to cut the eyelet bolts down to size...

And voila, they're in! A cool strap down point.

Hah! Sure the eyelets are nice (Quite nice actually) but we all know that the real reason you posted that pic was to show off your 60/8 Club sticker!😃

Jetting generally sounds great. Under 300F must mean it's quick but quick enough?
You mentioned jetting slight roughness. Probably just the pilot, try a 55/160 and see if the rough point is better or worse. Then this will give a clue as to what jet might be better. Note the change in mixture screw turns.

It's been a while since I posted here but fun stuff has gone on. B62, or the Blue Bomber as Chris calls it, has gone from a townie to being road worthy.

My benchmark for this is Yachats and back, which I did a few weeks back, with a couple of friends, Chris and Geoff.

I've also added Patrick's 3D printed venturi, which is deluxe. I've been riding the snot out of it, and.its running fantastic.

Then Geoff rode it for a bit and said that the shifter box is loose because the gears feel loose to him. Hmmm.

I just figured because it's a three speed and neutral is like its own gear, but nevertheless, I proceeded to see if I could tighten it up.

The gear stack is tight - I put a new spacer in when it was rebuilt, so it's not that.
The cables were tight at the batwing - not that either, so I removed the selector box.
Everything seemed pretty tight, but in order to grease it all up properly, the armature pin needs to be punched out.

That's where the fun began. The little pin wouldn't budge. I ended up drilling and destroying the batwing in the process. Damn it! So a new 3-speed selector box is on its way from The Market.

I probably should've left it alone. Live and learn...


Everything was tight - time to pull it off...

I pounded on that PIN for hours. Stupid me...

This is what happens when you don't drill out the pin straight. Aaarrrggghhh

Jetting history...

FYI, that pin is tapered. You were hitting it from the wrong side…

Aaaaaahhhhjhh!

So these directions are wrong?
https://www.scootermercato.com/Garage/Tech-Tips/Selector-Box-Rebuild

I even tried on the long end of the pin, but by then it was too late...

Never seen one that way in. Every box I did pin was going in from the outside…

Thanks SaFiS. I'll try it out on the new one that I ordered. I shouldn't have gone all nuclear on it in the first place...

Shouldn't have let Geoff ride it
Did he know you modified the rocker at the headset?

"Loose" shifting?
If there's no lateral play against the ratchet screw, remove the spring and stretch out by hand or replace it.

Just checked my stash. All but one are punched in the other direction vs the SM tutorial.

I'm guessing greasing the shaft would be for barn find bikes, NOS etc(?), since on a running bike it sits in oil.

Thanks Ray. You're right about letting him ride it!

Naah, he can ride it anytime, I just don't need to listen to his observations. He did just come off the Stella, which almost shifts itself, it's so smooth...

And thanks for checking your stash. I just got too rambunctious and didn't think for an instant it would be put together opposite that The Market illustrated.

In other words, I checked my brain at the door and get out the hammer!

While b62 is on the table, I might as well give it the full spa treatment while waiting for the new selector box to arrive. Happy Halloween everyone!


Time for a little rub-n-shine....
