First time out today on my trike, i need to do some adjustments, i sat right back when i measured things and in pactice i seem to sit l;ower thus my knees are too high. I dont think i will lengthen the boom as i found when i brake quick when i got back home that my rear wheel lifts. I think thats probably the reason the previous owner had the seat mount 4 inches back although on the thinner square tube, i can pack it out and put it back and this will shift weight aft. I do have a small viseo of the trike and also one of my small first journey today. Once i finish editing slightly i will post it on this thread.
