Hi all! I have a 2011 Tomos nitro 50cc currently with a 80cc bbk. And i was wondering what is the biggest cc size engine i could drop in this without any modding of the frame, basically just a drop in. And has anyone tried the 100cc longcase complete motor from scrappy dogs? if so how fast did you go and what bike did you have. cause i might get that. My goal is a cruise speed of 50 but not to have it wot so maybe a max of 60.
