This is strange. Last night I replaced my old chain/sprockets, kept everything to stock specs. I didn't do ANYTHING else. Now the quad won't 'wind out' in any gear. It just revs high in every gear(like its time to shift) and when I shift if immediately does the same thing in the next gear. I had it in 5th and it was doing maybe 15 mph at full throttle. Any help would be fantastic.
