Ok! I think i'll just leave it. might eventually do rings and a cylinder hone, but for now its gonna stay as is. I did order a compression tester anyway. just curious. its not an super expensive tool or anything and will maybe be useful in the future.
I've been thinking about it and it seems like since it went right around 25-30 bone stock, this leak probably isn't a problem since the wiki says the 103 u3 (my model) has a top speed around 30ish mph. with the new reeds, derestricted intake and exhaust, bigger carb, and exhaust port lip gone i'd like to see 35-40 mph but we shall see. if any body has any tips for my stockish setup Let Me Know! Thanks!
