My Dream Scoot Vespa ET2 Out of Storage

[pinkscoot]

I have a big enough compressor to use a HPLV gun and It's time I move away from rattle cans.

I'm going to try and power it directly from the battery, that should do it, I just need to find a switch and relay.

I see that. Have you tested it with another 35 watt bulb.
You should be getting about 13 volts there.

Well today after working on the SR50 I decided I wanted to take this scoot to get coffee in the morning. I bought a $800 Harbor Freight light and wire and ran straight from the battery. I used my second switch because I discovered the kill switch does what that switch did. It as pretty easy with everything open. Then I got all of the turn signals going and mounted a plate. I pulled the rear fender off and low and behold there were 2 holes that a plate fit on perfectly. This scoot is just about as naked as you can get a Vespa. No one will confuse this with a Ruckus though.









Opps I forgot Mirrors.

Edit: Now it is really a Rat scooter:

Well we went to get coffee and all went well. I need to do some CVT service and tune in the carb. The headlight draws power off the system and causes the turn signals to not be happy. I also lost the right side, I think a bad switch. Time to replace all of them. When I got there the kill switch wouldn't work so I pulled the spark plug boot off. Here are some pictures:



I put the old S50 seat on it to add to the rat look. The rear tire is almost gone so I'll pull a tire out of my old tire pile to put on it. It was the continental Zippy off the ET4.

The old pull the cap of the plug shock challenge. 😬

I kept my gloves on and didn't touch the scooter. But I did imagine that happening.

So today after riding the Sacarbeo for coffee I got down to working on the back end of the ET2. I want to pull the engine and give it a good cleaning and mount the Gianelli Reverse exhaust on it. First was pulling the old exhaust then the wheel so it could get a new tire. I found this when I went to the wheel:


More PBBlaster and off came the cotter pin and cap. Then I got out the impact gun for the nut. I was expecting It to be frozen and applied PB liberally, hit the trigger and off it came. The wheel slid right off and I was amazed at how clean the splines were. I pulled the old original Pirrelli of and low and behold the rotation was backwards. It came off well and the clean Zippy went on. You change enough tires and it gets pretty easy. It's always easier in the summer when the rubber is soft though.

Old

These Zippy's are nice looking tires.

Then the last thing was the frozen screw o the air box. It sticks out into the wheel area. I put to nuts on and tried screwing it out that way and the thread stripped. I then went at it with vice grips and really didn't have room to work. Tomorrow I'll get a Dremel and cut the damn thing off.

I then thought I'd play with the exhaust and see how it fit.


Like a glove. They say these do okay with 50cc's, I'll see how that goes. I'm not quite ready for the BBK, I can't decide what I want.

What is the wattage on that new light?
I'd keep an eye on the voltage regulator.

Sorted out the bits pinkscoot and boxed pm an address I will send them before the Xmas rush.

So these arrived yesterday, even though they were addressed to Pink Scoot. My UPS guy is probably curious. They are perfect and will dress this rat scoot up a little.

So on the last days of my week off I got this all back together and started tuning it in. While I had the engine out I replaced the oil lines and belt. I can see where the oil is now. I put some more premix in so it is smoking a bit. When the oil gets to the carb I'll dilute it with straight gas. I did find some interesting things while I was cleaning and I'll show them below.

The carb had an 87 jet so I thought I would go to 90. it was pig rich:

I went down to 84 and still rough so I went back to the 87 and it was better. I then raised the needle and it was better. took it for a ride and RPM's were just into the 7500 range. I suspect someone had been in and played because these are stock 76 main. I may try 80 and keep the needle up. I also got the CHT mounted on it so I can keep an eye on things. I'm thinking I may switch to a 19mm Phbg carb just to prepare for the 70cc kit. But let me see where I get with the 12mm I have. The Malossi one looks like it might be a nice way to go, it has a choke kit and plugs to open the air box. It also has the adjustments on the opposite side so that I can more easily tune the carb.

Next I went down to 5.5 grams and it would kiss 8000 rpm. I went to a slightly heavier clutch spring and take off was good but I still only hit 8000 rpm. I'm not quite hitting the pipe. Next tome I'm in I'll try 5 grams. While I was in there I serviced the clutch and it helped the ride. I got Millys parts and will put them on when I get my scooterpartsco order wit switches and other parts.

The exciter plate on the flywheel was a little rusty so it got some cleaning.


The 17 year old grease got replacing and it operates much smoother.

The head had this oil residue on it. It looks like the spark plug was leaking. I cleaned it and will keep an eye on fresh leakage.


I look forward to getting back to this scoot when work dies again.

I've had a couple of weeks off here and have been mucking about with this scoot. Thank you again Milly, I have the plastics you sent on it and its looks far less rat like. The head light works perfectly and I put an ignition switch in so I could put the glove box together. The carb has been giving me fits. Tuning it in has been a pain, I should have gotten the gasket repair kit in the beginning. I did manage to get it to quit leaking and have an okay tune to it. It starts right up and idles. I had put the stock exhaust back on and lowered the needle. I got it right and then went back to the Gianelli. With the Gianelli the the needle needed to come up back up. The plug looks okay but is oily around the base. I think I may not have a tight seal on the plug.


I tried a plug with a new crush washer and it helped. I'm not too worried because my stimulus check is going to get me a 70cc cylinder, just haven't decided which one. I can't decide if it will be this one scooterpartsco.com/vespa/et2/et2-performance/malossi-70cc-cylinder-kit-vespa-piaggio-derbi?zenid=2531ebe4acbc89a01439b946f4767516 or this one scooterpartsco.com/vespa/et2/et2-performance/malossi-70cc-mhr-replica-racing-cylinder-kit-piaggio?zenid=2531ebe4acbc89a01439b946f4767516. The cast iron one is a reasonable price and I know what I'm getting but the MHR Replica is a safe aluminum choice. I would appreciate anyones opinions. That Airsal T-6 at $109 is tempting. I could then spring for this scooterpartsco.com/vespa/et2/et2-performance/malossi-over-range-transmission-for-vespa-et2?zenid=2531ebe4acbc89a01439b946f4767516. Decisions decisions.

Is it still as fast as the night I was there.
You got a good rip out of it that night.
If I could see thru the helmet sure the smile was ear to ear.
Can't wait to see it all together.

Glad you found ur dream.

[pinkscoot]

Thank you David. Yes it still rips nicely.

Well the past few days I got the new carb tuned in. I was pretty disappointed in it. The PHBG's that I have are the racing black ones with the metal cap and metal fuel bowl with the bolt to easily swap main jets. I started it with a 70MJ and 38PJ and the 50 slide and needle it came with. After lots of trial and error I settled on an 80MJ 47PJ and 40 slide with a W9 needle on the 2 notch down. It does well an I was able to get it to 45 indicated. Temps hit 215F at WOT and would drop to about 135 at idle. It does not like to idle below 2200 rpm. I think that the slide needs to drop to 30, the 40 just pulls too much fuel when idling below 2200rpm. With the slide up that little bit its off the idle circuit. When I do get it below 2200 it just slowly stalls out. Nothing saves it. It also dies when giving it throttle. I'm going to take advantage of Treatlands sale and pick up a few more slides.

I swapped the plastic cap and fuel bowl for some spare metal ones. This carb fits better than the stock one because the fuel bowl isn't as deep so it doesn't rub on the rear fender. I was scratching my head about where to mount the enricher lever and decided it will go where the vintage vespas are located. For now I just put it in the opening below the seat. This scoot is as fun to ride as the ET4 but even better because its a loud 2 stroke. It is coming together nicely and looking less like a rat scooter.

[pinkscoot]

I forgot to mention that the 45mph indicated was with the stock CVT. I definitely think this scoot has the overhang kit in its future.

Good to see it coming together.
