water cooled knucklehead

my water cooled knucklehead is running like a champ, 1 kick cold or hot and doesn't miss a beat, does everything it's supposed to


  1. I saw Jesse's "Blacksmith" show where the Drake motor was featured. During the show the water cooled aspect of the motor was discussed and it was mentioned that the Drake has no water pump - water was circulated via "cavitation (had to look that up!)" if I'm remembering correctly. Was that an issue for you when you built your chop. Did you configure some type of water pump? Just wondering - beautiful bike, good luck with it...


  2. I ran a water pump under the seat that just pushes the water a little bit. so far so good, the whole thing was a learning curve for sure.
