Bolt, Connecting Rod

The most important mechanical assembly in the engine; if the crank/con-rod/pistons & bearings are worn or damaged then the engine will offer sub-standard levels of the smooth performance one would expect from Yamaha.
Renewing as many parts as possible at the same time, con-rods & bolts, pistons & bearings is almost like an insurance policy, when you know you have covered off every potential weak link in the assembly.
