[QUOTE="biglou, post: 123753"] [b]An Unconventional Idea Here:[/b] I read this thread earlier and a thought just occured to me. You may be able to pinpoint your leak by spraying a light soap & water solution around the gasket seam and then around the valves. If you can hear a hissing sound you should see bubbles immediately. I know this is totally unrelated, but this is a method of finding leaks in natural gas pipelines and home services (short of using the electronic sniffer). If you have a very slow leak, the bubbles will be very fine, almost fuzzy-looking. Keep in mind you will have to cycle the kick start lever to build pressure within the cylinder. If your leak is bad enough to actually hear it as you have described, I have a feeling you are going to see the problem right away. I don't know if this is a BAD idea, having never done it on a dirtbike, but I would think that if you used the soapy water solution sparingly you shouldn't harm anything. Once you pinpoint your leak, you may want to remove the solution somehow. And, hopefully, if you have to take it in for repair, you will be more knowledgeable about your particular problem when you turn the bike over to the shop. If anyone is certain that this is a very bad idea, please post! I haven't tried this but it seems to me that it should work. Hope this helps. :) [/QUOTE]
