Went to install my rebuild carbs in my 1989 Vulcan I had the one boot on the front cylinder. The other boot on the back carburetor with two guys first 10 fingers struggled for over two hours no matter which way from the right side installed could not get it done. We had to remove the boots, then put the carbs in, then reaching get a boot on carefully find the protrusion and line it up to the same on the other carburetor it fought us all the way I don’t know why we were having so much difficulty. We’re not done yet have to put the choke cable in next tighten all the boot clamps double check everything then still have to put the elbows in on the carburetor for rebuilt the air fuel mixture is reset to turns out I won’t be able to get back to you until next weekend. Assuming it’s warm enough in my garage just so mystified as to why I couldn’t get the carbs in with the boots on, I watched a lot of videos and it just doesn’t seem to be one specific way in which to and put them in some video say point them down push them in turn them no matter what couldn’t get it done I’ll report next week of success. We literally manhandled the carburetors didn’t do any damage but we sure as hell scraped up a lot of stuff.
