Leo: What I'd like, in a perfect world, is for the old mouse to top out near  , and cruise near 80. That is probably a tad optimistic, but something to shoot for. In the real world, even the new Kymco 4-valve, fuel-injected 300's are not quite THAT frisky... They'll often top  , but as for CRUISING, probably 75 is realistic... But, a few more useable mph would be welcome. And I know they're hiding in that old girl somewhere! I think they're sleeping in the variator... LOL!

What you would like from your 250cc scooter sounds like about the performance level I had from my 1968 six speed Suzuki 305 Raider. Those smaller two stroke twins would really run. It also sounds only a little bit slower than my current ride, a 2012 Majesty 400. Good luck in your power search. |

I'm glad it is living up to Yamaha's performance claims. The S Max may be well suited to somebody like me that only occasionally takes the freeway. Stay out of the throttle and break it in by the book. Here's the right way. www.mototuneusa.com/break_in_secrets.htmYeh, break it in by the book and you will likely wind up with an oil burning dog. Been there, done that, never did it by the book again. Work that motor, work it hard. Don't flog it, but work it. Full throttle acceleration to cruising speed is a good thing. Full throttle to get up a steep hill is good, a top speed blast for a few seconds is good too. Just don't cruise there at full throttle, and keep up with traffic. |

Hey JR, how about trimming the file size of the animated picture on your post. Three posts and this thread takes quite a while to load, about ten times longer than any other thread on my machine.

Yes! I used one like that as well. It saves a lot of wiring too. The tricky part is the regulator. If you tackle making the regulator part, be sure to use the PNP transistors, not the NPN type. That way the transistor cases and heat sink are electrically negative and don't present electrical isolation issues. Power JFETs have the same issues, but I'm not sure if you want the N channel or P channel ones. I didn't spend much time with them. It was a nice winter learning project for me, and I got a lot of friendly ribbing about it from my friends too when it was done. |

The comfortable, enjoyable speed depends on the scooter. If you are on a 50cc 15 to 30 MPH is comfortable. On my late, lamented TMAX 15 MPH was barely fast enough to keep the clutch fully engaged but 75 MPH was comfortable. My buddy on his Goldwing . . . even he dosen't know how fast the max speed is comfortable, but was a lot faster than my TMAX.

My google-fu is bad. I found 1500 dollars plus a mileage and daily fee of around $40 for a ten foot truck if you go over the time or miles you ordered.

U- Haul is an option  A scooter is a lot more than just a motor and frame. Do you really want to buy a piece of junk and be faced with sorting out wiring faults and fuel delivery faults, and ignition faults, and brake/throttle control faults on some random piece you would buy down there? U-Haul would charge a mint to rent a trailer one way. Bite the bullet and buy a Harbor Freight trailer kit for $300 www.harborfreight.com/1195-lb-capacity-48-inch-x-96-inch-heavy-duty-foldable-utility-trailer-with-12-inch-wheels-90154.html a sheet of 1/2 inch plywood and a few carriage bolts. Haul the whole scooter down and sell the trailer when you get to Florida. You will come out money ahead. Don't think you can't tow with a small car. My friend tows a trailer with his Burgman 400 on it between NE Ohio and central Florida with a several year old Prius, and I have towed similar and larger loads with small four cylinder cars for (mumble) decades. Whatever you decide, good fortune to you. |

I have no idea where you are going to or how far it is from your starting point. There are a zillion Cape What Ever and a lot of Spring Fields spread around the country. That being said, here are some points from my half century of riding.
1. Unless you have changed the gearing on your 50cc scooters, you need to keep the speed in the 30 MPH range for long distance. That motor won't last long cranking 10,000 at 45-50 MPH and you will be beaten to death in the first hour or two of riding.
2. A small tent, a sleeping bag, and a sleeping pad or air mattress and a small duffel bag is not a significant weight and can be bunged on the back of the seat. Think small and minimal for the accessories. Leave the two burner Coleman at home and get a small sterno stove. Cook the beans in the can they came in, and so on.
3. Tools and parts -- stay local and don't go far if you need to haul a service department inventory with you to be comfortable more than a few miles from home. Really. Truly. Been there, done that, and nearly always needed something I didn't have with me.
4. Dump your "friend" with the van and load as if he isn't going to show. Being hours late and not letting you know on a frequent basis is not the behaviour of a friend.
Good luck.

I have had the same faster at part throttle experience on my first Suzuki two stroke twin. After I put bigger jets in it ran even faster at full throttle. I know you said the dealer checked the mixture, but you have said your scooter runs better in extreme hot weather. That tells me you are running lean at WOT. Your density altitude is much higher at 100 degrees F than at 50 degrees F. Who are you going to believe, an instrument at a dealer on maybe a cool day during high pressure weather or your lying eyes?  Try a larger main jet. |

First, my experience. I have made three phase regulators with discrete components for my scooters which worked quite well for many miles. Here is a very basic overview.
Before you regulate the voltage you need to connect each stator wire to its own bridge rectifier.
You connect all the rectifier positive output wires together in one bundle and all the negative output wires together in another bundle.
You connect the negative wire bundle to the frame.
At this point you have unregulated DC current with an open circuit (no load) voltage in the 70 volt range.
You then connect the positive wire bundle to a SHUNT REGULATOR. This type of regulator regulates the load by grounding out excess current to maintain voltage control. All the current has to go somewhere, use another kind of regulator and you are likely to fry the stator. The shunt regulator ground wire is grounded to the frame and the positive wire lead to the battery.
Be sure to mount the rectifiers and regulator to a substantial heat sink.
Now, for the regulator, are you ready for power transistors, resistors, and zener diodes -- maybe an op-amp or two?
Spend time in electrical and electronic self study before you attempt this project or find a buddy who can guide you as you do it. It was a fascinating area of study for me and it took six months and several tries to get my first successful regulator built.

My son was telling a friend about my scooter and the accident and somewhere along the line mentioned I'm 69 and how large, heavy, and fast the TMAX was. His friend's reaction was along the lines of "Wow! How can someone that old hold up a scooter that large at a stop?" |

Depending on your supplier, you may have a decent brand name belt already on them. The three in the crate Chinese scooters I bought came with Gates belts. Check the scooters out out before you buy a bunch of belts.

Today for my TMAX I signed it over to the insurance company and cancelled the license plate.
Thank you all for the good wishes. I appreciate them.

It was totaled last wed. When the scoot and i got rear ended.
I am slowly recovering, but this riding season is over for me

People on motorcycles (non scooters) that feel the urge to over take you no matter if you are doing the speed limit, is like if their reputation where damaged if a scooter is ahead of them  Assuming your scooter is fast enough to truly keep up with traffic which is a different speed from the speed limit . . . A motorcycle rider with the geared transmission can hold a steady speed by listening to the motor but the scooter variator makes this impossible because the motor speed is steady but the ground speed isn't. As a result your speed isn't constant and the constant on and off the throttle for the motorcycle rider becomes annoying after a short while. |
