Hi, My TZR R is eating plugs, 2 today I have checked the settings on the carb 1 1/2 turns out and cleaned up the carb. The plug looks quite oily and after cleaning does not work, the spark from the bike is ok and when the plugs replaced it starts and runs fine for about 2 miles. I'm totally shagged out pushing the bike home, twice in one day Any help would be great. Thanks. Rich.
