Just an update to the uxv 450i, about 200 miles on her now and have switched all lubricants over to full synthetic. Still have not been able to acquire the factory service manual, cyclepedia is supposed to be working on it but have not heard from them yet. Finished the windshield top half today, brackets came in to complete my homemade polycarbonate upper for the cold winter months, it will come off when the weather warms up a bit and just the bottom half will stay on. Also put the finishing touches on the plow mount, will probably have to wait until next winter to see how it works. For what is supposed to be a quick release plow it sure is difficult to attach and remove, damn thing is really heavy, and I do mean really heavy. It is a very nice well made unit by Quad Boss, great design with mid frame mount but is supposed to be quick release and attach but due to the weight it nots very quick for this old body. Mabey with some practice it will become easier. My state requires a small license plate similar to a motorcycle license plate and I was looking for a mounting place....looked at the back of the machine and soon realized the rear cross brace support where the head rest supports cross is a perfect place to mount the plate. Drilled and tapped two threaded holes and the plate fits perfectly and jonny law should have no problem seeing it there. Shifter mechanism is getting better with use or I am getting used to it but it is shifting much easier now. Looking forward to other 450i owners to chime in on what they are finding with their machines.
