I used to ride a sportster often. We would run 800 or so in the back and the front as full as you could get it + wedge. You know you get it just right if the bow dips just a hair when you stop.
When i had mine i have 4 bags of cement under the back seat(sit bench on top of cement), 350 on each side of motor box, 350 in the bow....
1390 and 3 people int ehboat it was great. That boat was hell
Alright. I've got two 440s and don't know when I can get more sacs, but thanks! We can't really do any lead cause it's my gmas boat. Learned back rolls behind it
