I am new here and have not been on a bike in years. i just got a kdx 200 from my brother and it runs good but is dirty and pretty rough. the biggest problem is it is hard to start when cold. i bought a champion plug tonight hoping it will help. i won't get it out of the shed until it warms up since i do not have a garage. i will compression check it also. any advice for a newbie???????? what can i expect from this bike? i want to use it for trail rides in the mountain and a little fun from time to time.
