First of all, I am new here and have read some of the posts already about similar issues but none of them describe my situation exactly so I am just going to ask and see what happens.
Bought this LX50 today. Seemingly great condition, 772 miles and is a 2008. The girl I bought it from had taken it to a shop where I eventually picked it up. Just had an oil change, new air filter, cleaned out the fuel lines as it has been sitting a while. Fresh 91 octane which is the highest we can get here. I called the shop where it was and asked the guys opinion of the scooter and he said that he wanted to buy it from either of us so I figured I am in good shape.
Picked up the scooter today to drive back to Boulder. I noticed when I first drove away that it bogged a bit at full throttle. I didn't think much of it as it was about 30 degrees out and not warmed up. The mechanic told me that it would likely not go much faster than 30mph. So I drove away on a slight downhill and got to about 32 mph. The top speed of my ride. The speed slowly starts to get lower and if I go anywhere near full throttle, it bogs and begins to slow even more. I could coax it to hold about 26 mph. Again, didn't think much of it as there was a headwind, cold, etc. I stop at a gas station to top it off about 12 miles in and it will not start after that. I sit there and try for the next 10 minutes or so and nothing. I call the mechanic seeing if there is anything he would recommend and sure enough, as soon as he answers the phone, it fires right up like there was no issue. I continue my drive home, only another 1.5 miles or so home, and it dies on the way into the garage.
I begin my dive into the internet and see that this scooter is capable of 35-40 mph and notice that my 26 is a fair bit off that. I waited about 30 minutes and go down to check vacuum lines, as I have read about, they seem fine and it fires right up. Roll it outside and go full throttle immediately and from 0-12mph with no issue then wont go much more than that and I can feel it bog down. I take it out and can slowly apply the throttle and get it up to about 22mph but that is it.
Please help a Vespa noob out
