> Then, in Sweden, the speed limit for mopeds is 30 km/h (about
18,5 mph I think) and when mopeds are imported they slow the
mopeds down. Because most mopeds are made to go faster. And
when you make them go faster again, its called "trimma" in
swedish, dont know what it is in english (again) its illegal, but
what the heck :) > I need some tips on how to do that, make it
go faster.. I dont really know how to do, and my friends know
how to do it on YamahaFS1 and such mopeds, but noone knows how to
do with Puch mopeds..

I learned swedish puch engines have a smaller inlet. Make it bigger and it will already go faster. You might want to check out the carb. If it is a 10 mm, try to get a 12, or better yet a 15 mm bing. I'm currently working on a 4 gear Monza engine for a normal puch (MV 50). With a 55 cc engine bigger, inlet, bigger exhaustportal, highpressure head, performance exhaust and 15 mm bing it'll top near 80 kph.
For basic tuning, what your friends know about the yamaha FS1
will work just as well for a puch Monza. 80 might be a bit fast
for a country where legal speed is 30, but getting it to go 60 is
no problem at all (as in work, not legallity).
