Dumb Question
 

Heres a dumb question...first off let me.state my dumbness in saying.that i knew my rear tire seemed low but when i went to put air in it it was at about 4psi...and the front disnt even read. So needless to say i put air in them..now the scoot hauls pretty quick. My question is how can i tell or where is it stamped as to what size engine.is in this thing. Im curious if one of the two previous owners had put a big bore kit or what. Im pretty sure the carb is the stock 50 tho not sure how to tell on that one as well

Your engine type size should be stamped on the case near the kickstand. But the only way you can tell if someone put a BBC in it is to open it up yourself and look. Probably not worth it just for curiosity. Properly inflated tires is one of the cheapest performance upgrades ever.

Yeah i noticed lol i can hit 40 on flat now...rpm hits 9k but i hit 40 lol
