Hello All,Has anyone experienced a leaking decompressor. I noticed a brown stain around the decompressor and when I put a spanner on it was just tight and that was all.I removed the decompressor and lapped the valve into the body, blued the set to check that I had a complete lap which there appeared to be and generally cleaned the thing up.I used a new decompressor washer kit when I reinstalled it however the it still leaks. What I am hearing is a faint hiss sound as the enging is running. At this stage the bike has covered less then 1500 miles since new. Any clues??Roger
Leonard - Good suggestion about the spark plug - are the threads the same in the plug/decomp holes?
