Agree with the above. A larger exhaust is required to handle the increased air flow the GTurbo produces and avoid excessive EGTs. But keep in mind that higher air flow on the exhaust side also means higher air flow (vacuum pressure) on the intake side. This higher vacuum can cause oil to seep...
Here’s the best way I can put it. Owning an HDJ81 in the US needs to be your serious hobby. Otherwise, you’ll think that keeping it running in top form is too time-consuming, too expensive, or both. You have to enjoy the learning and the doing of the mechanical work yourself. And you have to see...
