My initial goal was to keep up with my wife. At the time I was around 300# and my boy would ride with me adding another 50+#. Then we started riding with another couple who have a C3 and a Zuma.
If I had it to do all over again I may have just bought a 150cc but I did have a lot of fun tinkering with it and its still a blast to ride.
From 0 to about 35 its faster then my stock 150. Cruises comfortably at 45 and tops out just a touch over 50.

Just to give you some Ida this is what it took to make my large frame 50cc faster then a C3 with my fat but on it.
Big bore kit what they call 100cc. IMHO best bang for the buck.
Large Valve ported head.
150cc intake and carb.
Custom made exhaust.
Complete transmission upgrade. Sliders, torque and clutch springs, and variateor
Iridium plug
Racing CDI. No noticeable difference.
Last but not least. Many hours of tuning and testing.

New means never put into service. Even if it only had 10 miles it wouldn't be "new"!

Welcome, very cool project! I have seen a double shock set up like you want to do. They had made up custom mounts. I have no Ida if you can bye anything like that or if you have to fab it yourself. I'm kinda thinking the one big shock Ida would be much easier.

Well you can hook positive to negative with one wire then hook the other positive to the load and the other negative to ground. This is a series configuration and will result in 24V witch would probably fry your scooter.

You would want to hook them in parallel like your first drawing. If you hook them in series you will get 24V. BTW the second drawing in NOT series. Its just a no no.

I run my 50cc with just a filter like that. 2 years no problem yet.

I'm probably to far away to help but since I work part time for a scooter dealer I do come across some good deals on scoots. If I can be of any assistance PM me.

There may not be any internal problems. Those mettle shaving are outside of the crank case and may be an indicator of the problem. I would look real close at what was causing those shavings. For example if the ignition pick up coil was hitting the flywheel it would cause a knocking noise and eventually the engine would quit.

Nice work! I wonder if they really need the forced air cooling when the engine is out in the open. You could remove the cooling fan and gain a little HP too.

Always interested in a restoration project. Looks like a cool little bike.

I usually tap on the head with a rubber hammer to break the seal loose.

I'm not a 250 expert but you should be able to remove the valve cover, cam and rocker assembly, then the head boldly and then A will come off and then B.

I'm thinking it should be hooked up to air cleaner housing.

I could be wrong but judging by the size it looks like part of the EGR system. Is it connected to a valve on or near the valve cover?
