Hey guys just wanted to share an opportunity with all my fellow yt60 riders in search of more power. After finally giving up the hunt for a DG or FMF pipe I decided to fabricate my own expansion chamber. 3 prototypes later I have a pipe that makes a rather large bump in torque from 1/4 throttle all the way to the top end of the Rev range. I weigh in at just over 170 and I can sit in the center of the seat and with no assistance from a 1/4 throttle roll the little bike will lift the front tire almost to the 2 o'clock position. I have no Dyno sheets but seat of the pants testing I have noticed a large improvement throughout the Rev range and on the plus side no more carbon blocked canister. If interested please pm me. Pipe costs $80 in 22ga mild steel with no silencer. Silencer can be built for additional cost as well as the pipe can be built out of thicker steel for additional cost.
