[QUOTE="geremacheks, post: 685498, member: 28410"] Wayne to the rescue: :thumb: Appreciate your post and your pm. I really haven't been around trials bikes much, so when I heard this loud popping and cracking at idle, I was really surprised. I remember reading over and over that trials bikes were quiet and you could ride them just about anywhere without disturbing anyone. Not so with this bike. It's the loudesd bike I have ever had and I'm an old guy and have been riding since I was 18. Anyway, I figured I could make it quiet with a little cleaning and packing, but so far failed. As I mentioned, the baffle is clean, and I did repack as you suggested: stuffed packing into the end cap, and even made the packing longer where it meets the middle silencer. You are sure right about the silencer's odd shape and difficulty to repack it evenly. Too bad that cap doesn't come off the baffle. That would make it easier to fill the silencer cavity up. The middle silencer: now that seems to be the problem, alright. (Where's the expansion chamber?) I like your idea of a mineral turpentine solvent flush. That sure is worth a shot. What's the best way to apply it. Take the whole exhaust system off? Are you pretty sure that the packing in the middle silencer is wire wool? Smart if that how Beta made it since it's so hard to get to the middle silencer. I do feel know that there is a chance of quieting this thing down. I hate loud bikes. Thanks again for your suggestions. [/QUOTE]
