Hey guys....a got just a standard 70cc pitbike a while back now and just wondering what big bore kits I could get for it....cause i've seen the 138cc kits goin round but arent to sure if that would fit??? All help would be appreicated.
 
sell it, and buy a 125cc etc

turning a 70cc into a 138cc just wont happen, and not worth the $$$,

even if you put a 138cc engine in your bike, is the bike gonna hold up to it???
cause the 70cc bike ive seen in the past was pretty poorly built, and no way woud have it handled 138cc engine,

100% spot on, theres no point stuffing around with the 70cc try listing it on ebay or in the mini classifields section and someone will want to buy it. i would recomend for you to buy either a lifan or jialing engine. you can contact maylands performance or other sponsers they sell good engines.
 
^^^ agreed, if it was a honda 50 yeh work the jeebus out of it, but just buy a bigger donk for it.
