I don’t know why it took so long to hit me – but the clone/Lifan engine is really loud. I took my phone app and pulled the stock Club Car next to my cart for some side by side comparisons. At idle the Club Car was 5dB quieter, which is about 50% less in perceived noise levels. As I revved the Club Car to 2000rpm, it gradually got louder. When I did the same with the clone engine, it was a night and day difference. It went from about 85dB to nearly 100dB at 2000 rpm. That just isn’t going to work.
Here is the same idle – 2000rpm on the Club Car:
I started researching how I can make this thing quieter and long story short, I found a brand new Honda GX390 for sale about an hour north of me. I took the drive and sure enough it was brand new. Brought it home and most everything swapped directly over. I did have to modify a few things due to differences between the Lifan 390 and the Honda 390.
When I was removing the governor, I added a cap instead of a plug for a future modification.
Ready for the Honda:
All bolted in place:
I am pleased and relived to report that the Honda is about 1dB quieter at idle and about 1 dB louder at 2000rpm than the Club Car.
