I just acquired a 98 Sportster 1800 in rough shape...all sorts of animals living in it, uncovered for years. Was going to pull the engines first and comb through them to see if this project was worthy of continuing. I think I have everything off and am trying to slide the engine off the shaft, but i can't get it off...it is moving a half inch or so. I assume i just need to get it up higher and muscle it a bit more, but my back is not happy after 8 hours in the boat yesterday and thought I would ask for any tips or oversights before I go wrestle with it more... thanks in advance for any help advice.
