I received a new set of heads for my bike yesterday, probably going to install them this weekend, weather permitting.
2 stroke tuner Roland Cushway machined these heads (2000 TZ125 heads) for my 1995 TZ250. The 2k TZ125cc head has a better combustion area shape and plenty of meat on the head for machining. Lends itself to be reshaped into a copy of the Kit-A leaded 1995 TZ250 heads. Should make for a nice overall improvement on power.
