New KLE500 owner

New owner of a 2005 KLE500 with 26.5k on the clock. Not new on forum, I also have a 2003 XR650R and a 2012 XR650L. Wanted something in between for more roads and less dirt. So far impressed with bike but she has some issues and seems to struggle to pick up revs although she does make 160km/h indicated but feels more like a 200 - 300cc in terms of power. Will start to get some work done on her and get small issues worked out because I think she is still 100% stock

Any vendors that can help? I need crash bars, after market handle bars, bash plate, what else you may have

Regards
