firstly, It's old as hell, chinese bikes don't last long from brand new so it's gonna be riddled with weaknesses and problems just waiting to happen
look at that airfilter, crap, can't be good for the engine
what's with those those tires?
front brake disk is ridiculously big for the bike
it's only a 110, unless you're 8 you probably won't be satisfyed with the power
lastly, it's old as hell, when u can get a brand new bike for around the same price why put yourself through all the trouble of replacing old worn out parts and possibly the whole engine very soon?
are you dead set on getting a 10"/10" 110? if not you should get a brand new 125 - 160 for a little bit more and save yourself a whole lot of trouble
