took the bike out for a bit today, the speedometer is overly optimistic, lol. It reads about 10mph faster than you are going. I don't have any really long stretches of road to test it out on, but I got it up to 42mph. Acceleration seems a bit slow. Not sure if it is a carb issue, maybe something with the belt or maybe it is just that it is likely heavier than other 150cc bikes. The engine sounds good, no real bad spots, smooth idle, goes through the revs just fine. I will tinker with the carb some more but it might just be that my expectations were a bit high.

Would you be so kind as to share a video of a quick run? That is,if you have the means and are feeling generous.
That thing's pretty neat. If you ever did decide to sell in the future...are you anywhere near zip 16154?

The front frame bent from normal street use. I never had it off road. I have 5,537Km on the scoot but the frame has been bent for some time. It is my opinion as an engineer that any sort of pounding on a trail would literally fold up parts of the front frame. Be careful if you ride it over rough terrain. Failure could be sudden and catastrophic. When the time comes I intend to just part mine out. The frame's weak links, do you feel it's something that could be strengthened reasonably easily with a welder and a bit of steel? I'm simply talking for street use.

The turning radius on these is far wider than you would think. Though most mopeds/scooters don't turn that sharp anyway, and this one was certainly designed as more of a "cruiser" and not something to go ripping through the streets with. I'm not complaining though, since I got it for $150 and so far only put $60 and a couple of hours into it to get it so it can be driven.
I'm sure I will sell it after awhile, I buy stuff like this to tinker on, learn about, enjoy for awhile and then sell to fund the next project. I'm in NC, by the coast...so a bit of a trip from you.

The scoot is a LOT heavier than a normal two wheel scoot. That 'beak' on the front is heavy and should be removed.
I am going to try to straighten the frame where it is bent now and reinforce it. The bent spot is near the rear upper A-arm attachment point. The frame is bending inwards. It has also bent the upper A-arm at the attachment point. I don't think it will ever be strong enough to take a big bump or a jump over anything. Maybe once.... crunch. Other upper suspension and frame points are slightly better but inadequate. The front suspension is also metal-to-metal at all pivot points. The ride is extremely rough. Two shocks in the rear don't help either.

Today I worked on trying to get the fuel tank working. I managed to clear the blockage in the output with PB blast and compressed air. Then I used my test tank to run the bike, while allowing the fuel pump to pump the contents of the tank (plus a half gallon of fresh fuel) into a bottle. As you can see in the pic, what was in the tank was pretty nasty. I think I will have to pull the plastics to remove the tank in order to fully clean it out. While I had some success there, I spent a bunch of time trying to bleed the rear brake now that I have a new master cylinder. I have tried a couple of methods, started with blowing out the line and brake, and while it will push out fluid and it seems like I get all the air bubbles out there is still no pressure. I'm almost wondering if the new master cylinder is defective. If the brake line had a leak, I have surely put enough fluid through it that I would have found a leak by now. So progress is slow but there is some.

Figured out how to drop the fuel tank from under the bike, without having to remove all the plastics on the top! Hopefully after several rinses it will be clean enough to use. I also bought a brake bleeder kit, as I can't seem to get the rear line bled. It is a pretty long line, and there are no leaks, the master cylinder is new and the brake caliper/piston all look good with no leaks, so there is no reason it shouldn't work other than there being air in the line.

I was able to clean the tank out. Sadly, I didn't get everything out so the first run got junk in the carb and it had to be cleaned. Once cleaned I let the pump run the crap that was at the bottom of the tank and after a minute or so the gas cleared up. She pops ever now and then, so I may need to enrich the fuel mixture a bit. I removed the fenders to paint them, but having them off looks kinda nice...might leave them off and just paint the rest black.

That pic from the 24th...who put carrot juice in that thing? It must have a steel tank?
I've had luck with BBs or even gravel (and water) inside of tanks followed by lots of shaking and rinsing to clean them out. Got the gas tank on a 68 Kawasaki c2ss free of rust using BBs. Gravel made the coolant reserve on my Daytona look like a new bottle.
Sounds like you've taken care of it though. I'd still like to see the trike stripped down. Thanks for the update!

The front fenders are the same as a regular two wheel scoot just mounted on brackets. That way they didn't have to come up with new molds, just add weight for the mounting brackets. The front tires will spray water when riding in the wet without fenders.

gave it a quick spray can paint job today, it isn't pretty, but much better than the faded and cracked "grampa tan" color that was on it

Looks good.
You can drop some weight by getting rid of that heavy front bumper.

Awww...run her till she spits you out like bad tobacco. Then part it out.
I am looking to do my Gyro rear drive similar that front, but without steering. The biggest obstacle is speed bumps every 150 meters.

Speed bumps can be 'removed'

man, the rear brake is being a PAIN! I replaced the master cylinder, and then the brake line...still no function. I have both manually bleed, and used a compressor powered brake bleeder, but nothing. Next step I guess is to remove the caliper and take it apart...maybe it got rusty from sitting.
