Crankshaft: No crank mods required.
Crankcase: No crankcase mods required.
Notes: This kit requires you to send us your cylinder, head, and power valves for modification.
The YZ134 is a great kit. More everywhere over the stock engine with tons of over rev.
These used to be AMA legal in the 125 class so we have sold a pile of them over the years.
We use a custom ultra light weight Wiseco piston that is 3 grams lighter than stock. If you have a YZ125, scream all the time, and are leery on the whole big bore thing the YZ134 is for you.
