I cannot get the fuel screw to respond on my 96 XR200R. The carb is spottless, however when I put a rebuild kit in it I noticed the taperered end of the fuel screw was damaged. The end was slightly mushroomed and had a slight bend to it. How easy is it to damage the body using a bent screw? Is there any way to check if the seating area is damaged? Has anyone seen a damaged one, and what were the symptoms? Is ebay the best bet on sourcing a used kiehin body?
