well, I don't know if I should be ashamed but I have a 2005 Primo Seville. I got it for free so I couldn't resist plus it looks pretty damn good. Originaly I am from eastern europe but have been in the states since 99. I was told that my scooter has the same engine like the yamahas but I am not so sure. The max speed after the brake-in period that I've done is 46mph. It's a 49cc btw. It runs pretty good but there is something in perticular that bugs the crap out of me. Around 32mph it kind of bogs down for a while until it reaches 35mph when it starts to pull hard again. At 46mph it runs out of breath. I guess the first mod that I would like to try is a new carb. Now, do I need a 22,24,26mm or whatever. After I get it how do I know if the jets are the best for my needs/performance. How do I set those up? Actually I tried a K&N style filter and the result was really bad-the bogging down got even worse around 30mph and the top speed dropped a little. I didn't have any velocity stacks or anything though plus the filter was shapped like a cylinder and not like a cone(for some reason I have the feeling that this matters). Besides this "mod" the only other thing that I've done to it is strip it down and repaint it in a killer blue

Another thing I would really like to do is convert my rear brake from drum to disk. I am sorry for all these newb questions but you guys don't really have a sticky explaining what parts do what. I hope that this tread may become one in the future. These are some questions for a start:
1. Two stroke engine exhaust pipe-how does it work and why the funny shape? Silencers and their pros and cons?Different types and their differences?
2. Engine kits-70cc,100cc.....
3. Carburators-different sizes?Adjustments?Jets-kinds and when to use?
4. Drivetrain-belts,clutches,variators-everything about them...
5. Whatever I am missing goes in here.
As a member of many online forums I am really pleased to see how this one looks. However, I can feel that it's still in a very early stage of development. With some stickies like the ones above, it will help new people understand the scooter mania and get more involved because honestly guys, when I go through your topics I have no clue what you're talking about 80% of the time and as you probably know there is not a lot of information out there. Well, that's all I have to say. I hope I didn't put all to sleep and that togather we'll biuld the BEST scooter site on the net...
