i had a 91 KDX200 with the usual mods, i crashed it hard, hit someone head on, came up over a hill didn't see them, it destroyed the front end of my bike, forks, front wheel, and cracked the right side engine case and clutch cover case, would've cost more to fix it then what the bike was worth, so i'm in the proccess of selling it for parts and recovering from a broken thumb, the guy i hit broke his right femer, ouch, i probably won't have the head done if you have to run race gas but i might have the cylinder ported
