I have a 2005 VTX 1300, the bike was ran without oil. The first thing we did was put oil in it to see if it would start and it would but we couldn’t rev it over a certain RPM then the bike would shut off and just turn over. Now it won’t even start. I’m not mechanically inclined and have no idea where to go from here. Wondering if I need an engine rebuild or engine replacement and how much it would be. Could I do it myself with YouTube or do I need a shop?
