i have the pipes /modded airbox lid
wire splices
head conversion
hrc jet kit
tyga reeds / stuffers
NO port work has been done
the guys that prep my race bike are 2 stroke lovers so they do all my dyno work/jetting for free (top blokes) so dont know about the jetting
each part was put on then dynoed to see what gains were made i think the head added about 1/1.5 bhp i do have all the charts some where but cant find em
the bike is doing 61 bhp at the wheel
they are trying to reshape a spare set of throttle slides at the moment to gain some more midrange
