assuming his 0.011 is inches, he's at 0.28mm, sounds like a win

always good to specify the units in an international context.
Hope it's not in yards

yeah, the Sprint motor is not an EFL gearbox. It feels a little different when you ride it, but not terribly so.

The project is looking great! It's making me think about getting my GL project moving forward despite the cold in my unheated garage.

I don't know for sure what it means, but i'll take a stab at it. Maybe someone can correct me?...

Originally there was the P200E (E meant electronic ignition). Around 1983ish the PX200E was introduced and marketed as "Lusso" series...which was the same time that the whole transmission was upgraded to what is referred to as an EFL transmission (no idea if it was called EFL back when it was first introduced). So perhaps EFL was Elettronica "?xxxx?" Lusso? Don't know what the F is. Like i said, this is just my guess.

Electric Fuel Gage? This seems the notable feature in all PX models, along with the electric starter.

I would think Piaggio would have used Italian and not the English language though. And I donít think all the PX EFL models were electric start. I would think that whatever is means that it would be common knowledge by now, but maybe not in the US as much though? The only EFL model that was officially imported was the 2005 PX150. So compared to the rest of the world, we have very little experience with that transmission.

I ordered some parts yesterday. Front suspension bearings, a new piston, the correct set of seals and correct engine gasket.
Iím hoping to start putting the motor back together when the parts arrive.
I tried to order the locking washer for the gear selector, but SIP was out of stock. I straightened out the old one and I think itís in decent shape.
Scooter body is still in the body shop, hopefully Iíll get it back soon.

Engine mounting Bush problem
This morning I took out the old engine mounting bushes. I did it wrong, but I got them out.
I started to install the new mounting bushes but they donít seem to fit right. I double checked my SIP order and what they sent sent me is correct for a Sprint Veloce.
I installed the smaller Bush first by putting it in the freezer and heating up the small end of the swing arm. I did the same with the larger Bush but it was a tighter fit, so I used the supplied bolt to pull it into the swing arm. The larger Bush is not completely inside the swing arm, but it wonít go in any further due to the fact that the two bushes have already met in the middle of the swing arm.
Iím not sure what to try next, hereís a couple of pictures of what Iím dealing with.

Is the other side in too far? If not is the new set wider you could compare with your old sleeve. I had trouble with the type you are installing so I used original rubber bushing replacement and reused my tube. Did the same with the Bajaj too and was careful not to damage the sleeve tube on removal as I had done previously I learned that time how to get the end washer off and get it to go back. Good luck I hate this job.

I also used Clauss Studios those fit in nice.

Vpf- if you can shoot a pic of the end so we can see the opening - it looks like the issue may be that the center tube is now pulled in but the outer metal tube that surrounds the large rubber mount - isnít fully pressed in.

Iím other words, itís like itís being turned inside out.

That can happen if there is a lot of crud or even some small hard bits in the engine case where that mount is supposed to seat.

But it may just be snug fit.

Suggest: take large socket - must seat on metal ring surrounding rubber. Flip the socket over if needed to get a good flat surface against the motor mountís outer metal ring. Use a heavy mallet and chase the mount in using the socket as a drift.

If it doesnít go in nicely - remove it and clean up the inner surface of the motor casing, line it a bit, and try again.

Here are a couple more pictures. I was able to easily remove the smaller bush and the tube inside the bush protrudes the same amount (it looks like the correct amount), on both bushes.
I think Iíll pick up some large washers from the hardware store tomorrow and pull the larger Bush the rest of the way in.
I think the tubes are too long,

Rather than using a hammer, double check all your measurements with a tape measure or calipers first before you go any further! Measure the frame width, measure how deep the bushings are supposed to be pressed in, ect. That will give all the exact info that you need to know if what you have is correct or not.

Looks like you will find tube needs to be shortened. Pic showing end is clear - not inside out...

I rechecked the old tube and length is 8.25 inches, measured the new bushes and the total length is exactly the same. The reveal, for lack of a better term, (the part of the metal tube that protrudes from the bush) on the new bushes is .125 inch, on the the old bushes it was .25 inch. So I think Iíll pull the large bush in a bit and reinstall the small bush. They will both stick out the same amount. I guess the frame never actually makes contact with the swing arm anyway, it only touches the ends of the tubes.

I was able to get the swing arm bushes installed. They are not quite flush with the openings in the swing arm, but I guess that is how they were designed.
Also installed the crank bearings, cold crank, warm bearings and they went on easy.

Painted rims
I got around to painting the rims today. I cleaned them up as well as I could and then taped over the lug threads. I used a primer, paint and clear coat.
Iím okay with how they turned out.
I ordered a hot plate from Amazon and Iíll start on rebuilding the motor next.
I painted the steering column too.

Thanks Voodoo, but your front suspension looks fine to me.
On mine, I installed the spring attachment backwards and had to redo that, and then when I put the wheel hub on it was rubbing and I realized I had left out spacer washer. I had to pull the axle and one of the bearings to fix that.
Iím going to clean up the garage and start putting bearings and seals in the motor next.
Still waiting for the body work to get done.

I installed some of the seals and bearings this morning. Iím using a hot plate to heat up the case halves. So far thereís been no issues. The scooterwest video mentions a circlip on the clutch side that acts as a stop for the seal, but this motor doesnít have one, maybe because of the auto lube. I think I got the seal seated properly.
The crank is in the freezer for tomorrow.

Hot plate verses allunimum is a good idea. But I guess it won't do any good now for dropping the bearings in with those nice rubber seals in place?

Iíve been watching a very good video on rebuilding older 125-150 motors. The video was made by scooterwest. They heated the case half on a hot plate with the seal installed. They suggest using tinfoil or something similar to keep direct heat off of the seal. Iíve got both bearings on the crank already, hoping to get it installed on the clutch side tomorrow, after I finish shoveling snow.

I have the factory seal drift and when I did this on my Sprint, I used that as a heat sink, then heated the cases with a heat gun. Worked like a charm.

To the left is my modified selector rod wrench. Also I rebuilt the Cush drive and banged it up some peening over the rivets, but I think it will work fine.

Cases back together
I got the cases back together this morning, also able to install the cylinder and new piston. I have a question about the cylinder head, but Iíll address that in another thread.
Iím soaking the clutch corks and hope to rebuild the clutch tomorrow.
I sure wish I had the scooter body back from the shop!

I got the clutch done, also cleaned up the cylinder, the cylinder head was trashed and Iím waiting on a replacement ( Thanks Tierney!).
Iíve got the carb apart and itís soaking in carb cleaner. Itís a 20/20, which I think is good.
I checked the jets and they are

You must be getting excited, I find these motors so interesting. Some day I'll do some reading just to learn how these 2 stroke motors actually fire.

Oil tank installation
Got some Sprint parts back today. (Scooter body should be ready next week) I installed the new fuel tap and the oil tank onto the (freshly painted!) fuel tank.
The oil tank install is kind of tricky, the regular 17mm socket wonít work because of the cylindrical filter, so I used a deep well socket with a second 12mm socket inserted inside. That kept the 17mm nut in place and allowed the filter to nest into the nut.

Frame
It took A long time, but my Sprint is back from the body shop. I plan to start putting her back together next week. I rebuilt the Veloce motor, and got new tires.

Which seat?
I'm making progress on the old Sprint, rebuilt front suspension, rebuilt the 74 Veloce lump, (seals, bearings, crank, piston) new cables, a crappy paint job. I had fun wrestling with the glovebox side cowl, but it looks okay.
Motor is in, cables hooked up, wiring is done, (fingers crossed)
I bought a long seat a while back, but the old saddle style that came on the scooter is kind of nice too, it needs a little work though.

I like the bench/long seat, personally. Too much looking at bodges with the saddle seats on them, maybe.

Scoot looks good.

Seatís a personal choice. Iíd personally go with the bench. If you go with a saddle, Iíd ditch the ďbuddy seatĒ and put a rack on instead. Just my opinion.

Very nice Falcon! I love the paint color choice. I'm also a bench seat kinda guy, but like the modern plastic base seats because there is no spring tower. I find I sit right in the middle of the seat due to not wanting to ride with my knees in the legshield.
