I have this exact scooter and I did absolutely nothing to it except put her together and ride it. It is all stock from the spark plug to the belt. I change the oil with Yamalube 10W40. There's a Yamaha dealer just down the road so that's what I use. The only advice I can give is break it in according to the book. If you try to get too much out of her before she's fully broke in (about a thousand miles) the float bowl will run dry on you and she'll die. I drove 2,400 miles in the year since I've had mine and I can run at wide open throttle now all day and she runs like a champ. And it's still all stock. I haven't even changed the spark plug yet. But I'm going to do that soon as it's warming up again.

The guys on this site know a lot more about scooters than do I, and they're going to tell you to do this and do that. I listened, thought it over, then decided against doing any mods and I'm glad I did. She runs just fine right out of the box. I figure if the Chinese can put a Space Station into orbit, they can certainly make a scooter. No offense fellas.

I still think you were turning it the wrong way. Hehe. Just messing with ya!

I've been wrenching on things for 40 years and to this day I have to stop and think which way to turn a nut or bolt when it's upside-down. I have twirl my finger in the air to decide which way to turn an upside-down bolt to loosen it. I know right! So I'm not trying to be a smart arse when I ask, "are you turning the cap the right direction?"

When the weather is nice, a round trip to work and back is 20 miles. It's just been too darn cold for this old(er) guy and Betsy Mae for that matter. I won't start her under 40 degrees. In another month I'll be on her every day again!

How about making it into a three wheeler?

What I've read in your initial post, and saw in the video, your right blinker appears to work correctly, except for the front lamp doesn't light. For that I would suspect the lamp itself or the lamp socket. Perhaps even a wire attached to the lamp socket.

If that's what the problem is then one side of this system is working, and presumably, wired correctly. The other side of the system should be wired identical to the working side, but those wires will go into the plug in, probably, different holes and more than likely, right next to the working side.

I never like to trust wiring diagrams that aren't specifically tailored for a specific machine. Generic diagrams are just that. Generic. Who knows how or why a manufacturer wired the way they did and to what. If at all possible you should keep the wiring the way it came on the bike.

Access the wires on the back side of the lamp sockets, note their colors, follow them into whatever wiring harness they go into, find them again on the other side of the harness, then see what block they go into. The other side of the bike should be identical. Note any similarities or discrepancies and go from there. That's the monkey I would chase anyway. For what it's worth.

Well, since you included me, I'll throw in my two cent questions.

Has this problem always been a problem since you've owned the bike or did it just now start happening? If it just started happening then you can rule out the repaired and/or missing and burnt wires. If it's always been like that then that wiring may be part of the problem.

And, have you confirmed that the turn signal lamps and sockets are good? When my cars' turn signal lamp burns out the flasher doesn't flash the lights and maybe scooter systems work similarly?

Since both sides of the bike's turn signals should be wired the same, then I would check both right and left wiring from the lamps backwards and see if they are wired exactly the same. You might find that whomever messed with that wiring at one time caused this problem?
