So all these engines are in the 120+ range are taking out other components on the bikes............ pretty much sums up what I've said. While our sampling here is less than 7 bikes total, the trend starting to show is already pretty clear! It looks like most of the owners posting have all added clutches, transmission components at a minimum to keep them together. Others have added oil coolers, cooling fans, chain drives ect. With that in mind if your plans are to go into this power range be prepared to add a few thousand more dollars to the build above the engine cost at a minimum to add the necessary support items to have them live.
