stall

hi guys i recently lowered my bike and now it wont start in gear it starts in nuetral but not in first which would be annoying if i ever stall i just have no idea where to start looking im not as mechanically inclined on bikes

I own a 1997 Honda CBR600 and have owned it for a little over a year now. Im not new to riding, but Im not incredibly knowledgeable on the mechanics of my bike unfortunately. Situation is, my bike has been running great since Ive owned it, and the previous owner was an older man who babied it...
