It was faster on the road with turns because I caught a little tailwind.
I switched to the stock 105 main which is larger than the Keihin 105 and smaller than the Keihin 110. Moved the needle clip up. Adjusted the mixture and float. Still have a bog if I try to go WOT fast from idle or just above. If I get it revved up just a little or rev it up just a little slower it's fine. I'm thinking it need a larger pilot, but none of the jets I have here fit. The jets I have worked on 2 other 150 carbs, just not this one.

Brent your blowing my freeking mind with all the numbers and math!
I dont know why your scooter is so slow. I just had a customer with my bbk, the leovince exhaust, naraku variator, 1500 pill springs, 1000 torque spring, 7.5G sliders, 95 main jet, perf coil, and IX plug and the thing is a little monster. Just going around the block it did 50 on the speedo (more like 45 ish) with my fat ass on it and it hasent even broke in the kevlar belt yet. Im very suspect of the gearing in your scooter.

I've been wondering myself. It's not for lack of effort. I can't seem to find a pilot jet. I've looke dat jetrus, motorcyclecarbs, and some scooter places and GY6 jets are supposed to be THIS. Mine's not. I forgot to take a pic, and I've had the carb on and off enough for now. Here's a basic idea of what this one is like...

How about a rebuildable carburetor with jets you can actually find? Ive got a box full of them.
Let me just say this. After hanging with you and kliff for the last month or so I have thrown just about everything I thought I knew about these little motors out the window. You be breaking new ground JIMMMaaaa!

I don't know what I'm gonna do with this thing. After getting the carb straight, other than the pilot jet, I stuck all the panels on. Of course, as soon as I get the panels on it starts idling funny. I thought maybe I pinched something or disconnected soemthing. Nope. I bumped the idle up through the access panel under the seat just to make sure it wouldn;t cut out if it got worse. I tried clutch springs and torque springs and they hurt performance. I was getting a little pissed and discouraged when my father showed up. I told him about it, then said, "$%#& it. Hop on there. We're riding somewhere."
We rode about 5-6 miles at around 34MPH into a headwind. We got to a stop sign and he asked if it was alright to ride farther. I said, "I don't care, go wherever you want. I'll follow you." He headed out and went down a twisty road. This road has a couple of bad turns, one of which is a very sharp 90. He was cruising at about 34-35MPH coming up to this 20MPH turn. I'm just hoping he has sense enough to slow down, because it's beyond his skill to do that speed on that turn. I watched him cut across the yellow line, then panic and try to slow down. Well, we all know that you don't change your mind in the miuddle of a turn, you have to commit to it at that point. He straightened up and ran off of the road through a ditch that is barely a ditch (luckily) and crashed in a soy bean field. I pulled over and went over to him. He was on his knees by the time I got to him. I said, "Are you alright?" No answer. "Are you OK?" Then I heard a strained, "Get me up." I pretty much had to pick him up off of the ground. I said, "you knocked the wind out of yourself" and he told me his ribs hurt. I asked if he needed me to call help and he said, "no." I asked if he wanted me to get someone to pick him up or did he want me to go get the truck and pick up him and the scoot. He said, "No, I'm fine"... still barely able to talk. He proceeded to tell me he would ride the scooter back. I explained that the last thing he needs to do is crash again because he's hurting etc.. He refused repeatedly.
He ended up riding home, very slowly on the rest of the twisty road. He got up to about 40MPH at one point on a straight road with a tailwind, so I figured he must have started feeling better. We got to the house and I noticed him struggling in the stones, where it takes more effort to control the scoot. I went over and he was making noises like he was hurting.
He ended up going to get x-rays. He's got fractured ribs and contusions. Now that he's had plenty of time to stiffen up, he can barely move and says it hurts to move, talk, eat, or even breathe. He's on pain killers and won't be able to work tomorrow and maybe not by Monday. Whenever he can go back, he's supposed to be on very light duty.
He was worried about hurting the scooter and kept apologizing. I said, "I was about ready to push it into traffic, so whatever.... it wouldn't have hurt my feelings if that turd caught fire and exploded." lol As long as he's alright, I don't care. I haven't really looked at it. All I know at the moment is that it broke the mirror, the speedometer is gone, and the exhaust is leaking now. I'm sure I'll fine more than that. I told him the scooter might have to go. He said, "No, I'm gonna keep riding."

I'm sorry your Dad got hurt. He's a real trooper. And you gotta admire him for wanting to climb back on. Cracked ribs are pretty painful. Hopefully he'll be much better in a few weeks.

Yeah, he's a tough dude. He used to box and kick box and teach martial arts and boxing, so he's had cracked ribs before. Not that that makes it hurt any less unfortunately.

The Sunl might actually get sold. I'm not 100% sure. Originally, I told him the scooter needed to go. It's too slow for me to want it and I'm really starting to wonder if he should be on 2 wheels after seeing what happened last night. He is adamant that he will ride again and that he'll be fine. He says he saw the truck back behind s and he didn't wanna slow them down. I said screw them. They'd be fine and the coulda passed if they wanted to. The he hints that he wants to be able to go faster so he doesn't feel like he's in the way. In a nutshell, I told him this... "Well, that's the wrong attitude for anyone riding a scooter or driving a car for that matter. I can drive 60MPH and some fool will get on my rear like he's ready to push me. People are just ignorant. You have to ride however you are comfortable. Keep an eye on your surroundings, but don't do things that scare you just to please someone else. I'd like you to stick around for awhile, and you aren't going to if you do stuff like that."
Now it sounds like he isn't very comfortable with the braking either. I don't blame him. I think I could stop from 60MPH as fast as he could stop from 30-35MPH. The suspension setup is just poor IMO. I personally believe it is still alright for 30-35MPH with a decent rider, but if someone that does stuff like my father did gets on there it could use more stopping power. The real problem is the rider though, I do understand that there was no need for him to be in that situation... so don't think I'm blaming the scooter. Just trying to figure out how to get him as safe as possible if he does ride again. I've already informed him that if he expects to ride with me again he's gonna be spending more time practicing. I'm not really sure how else to make him think and react when he rides. I'd hope all the pain he's in right now would help him reaslise he doesn't wanna screw up again.
So do I really wanna do a pricey disc brake conversion and lots more engine work or an engine swap to a scooter that's tiny with a suspension that's lacking and little 10" wheels? I'm thinking NO. I'd be better off to sell it and buy a brand new scooter from one of the sites that offer them in the $500-$600 range shipped like American Mopeds. Or maybe I should sell it and put the money into my original Triton. I'm pretty sure that would be fast enough for him. I know it's got good brakes an I know it handles well. I've also followed him while he rode my Triton before and he did great on it. He's had the one I ride now up to nearly 60MPH and taken it down back roads with no problems other than forgetting his turn signals and stuff when he first started out. For that reason, I know he's capable of riding just fine.
So if I sold the Sunl, I know it's not worth much. Maybe I can get 3-400 out of it if I replace the speedometer and put mirrors on it. If I'm only getting that price, I'm taking off the exhaust, swapping in the stock cam, putting the 72cc head on, using the stock carb/intake, and going back to the stock variator. It will probably still go the same speed. If I don't end up with another 4 stroke, at least that stuff might sell for some extra cash. I don't really know what I'm doing right now. Just thinking out loud. If you guys have any thoughts or suggestions, shoot.

I could use help on some decisions probably. Here's what it needs and what I'd need to figure out if I go with the Triton...
I need to get the cases cut to accept the 45mm crankshaft. Then I need to figure out what sort of BBK it's gonna use. I'm kinda torn between going with a 54mm big bore kit for max displacement or a 47mm big bore kit for a couple of reasons. A 47mm kit would put it close to square. There are alos 47mm kits out there with decent ports for reasonable prices. The big big bore kits that I see offered seem to have pretty standard ports. Also, if I go with a 54mm kit it means more case cutting. I'd have to use a modded stock exhaust for a while. Not so sure I'd trust a little carb on this kind of setup, so I'd wanna get a bigger carb/intake. I've used some parts off of it to keep my other Triton going, so I'd need some odds and ends. It won't be cheap, but it might cost less than a new scoot and it would surely be better and faster than any scoot I'd get for $500-600 shipped.

You wont be happy with that 5-600 scoot,it'll be a dog and the process will start all over again.Any places you can go to test drive a low end scoot?If you could find a 2stroke for that price,maybe so,but then it'd need a cyl kit and pipe.... I have an autotech355 48mm cyl kit,the port mapping is an exact copy of an 'Athena' cyl kit.It runs well except if the dumb rider has a lean spot and holes the piston!Here is where I got the mapping stuff from www.scooterinvasion.net/forum/viewtopic.php?t=488
