[QUOTE="Pit_Monkey, post: 156067, member: 23335"] i blew the topend on my bike and i called eric the other day and he talked to me about the different options i have and ive decied to to bore out the cylinder and have it replated. however i cant decide wheather i want the 134 or the 144. also i have to decide wheather i want it to be ported for mid to top or bottom to mid. as i discussed with him on the phone i live in ct and ride pits and woods. however i love the topend pull that my bike has to it. my friend has the same bike but has a fatty pipe on his instead of a bills. so his power is shifted down to the bottom instead of remaining on top. when i rode his bike i hated it. it redlined at around 3/4 throttle. but it had massive bottom end pull. so im looking for anyone with a yz 125 that has had the ama bore or the big bore kit done by eric and has had the porting done to the cylinder to reply to me with there thaughts. my only concers with the mid to bottom porting is that ill lose my top en power. any replys are much appriciated. thanks:silly: [/QUOTE]
