I've never had one, but I have nothing against an Express, or any other noped. Hell, I even own a SCOOTER. An Express is not likely to become a collectors item any time soon. As for modding it, there are pros and cons. I have a stock Puch, which I believe IS becoming a collectors item, I have a stock Tomos, a slightly modded Tomos, and a fully kitted Tomos. The stock Tomos is an '03, has 16,000 miles on it, has been used mostly for all day and all weekend trips, and has been absolutely trouble free, and probably has a lot more miles left in it before it needs any major repairs. The slightly modded Tomos is an '08 Sprint, with only a Biturbo, Unifilter, rejetted carb, and 22 tooth rear sprocket. It does around 42-45 mph, and I mostly use it to run around town, because it will keep up with cars. I figure it will last maybe 10,000-12,000 miles of stop and go use before the bottom end and transmission fail. The kitted Tomos is an '01 that I bought with a little over 1000 miles on it, and was kind of beat up, ( mostly plastic parts ) but mechanically fine. It has a 70cc Airsal kit, 15.15 Dellorto, Unifilter, Tecno Estoril, and a 27 tooth front sprocket. It does about 50. I just bought/built it as a project, and something to play with, with my GWB money. I don't expect it to be reliable at all, and certainly would never leave town with it. BUT, I do have a cheap source for Tomos engine/transmission parts, some used, some new, that probably very few if anybody here knows about. So I can keep it going without going bankrupt, and it's not like I need it for transportation. And that is what it comes down to. If the Express is you main source of transportation, I wouldn't mod it to far. You can't have fast and reliable at the same time. Peace, Jerry.
