2 out of the 3 guys have giving you good advice, check compression,plugs, jetting and go from there don't let people that have only been a member since November discourage you. As the advice was given search search and search again do as much reading on the bike as you can and also research the mods you think you want compared to the style of riding you do. Ride it till it blows them spend thousands fixing it lmao have fun and good luck.
