Well...for now slide stock forks up an inch once new seals go in...because seeing what is up with motor more important for now. Carbs were off at purchase time...when battery shows up I will try and fire it up and see what old owner meant by excessive vibration.The zx6 forks are about 1 1/2" shorter than stock, but the upper sits lower so the height difference is less. Overall I did shorten then kickstand about an inch to get enough lean.
