A clean pipe, fresh silencer packing, proper jetting and the correct heat range plug will pretty much eliminate it. If you seal the pipe connection tight all it will do is fill the silencer packing with spooge.

Keep it up on the pipe, low rpm and low premix (30:1) will cause alot of spooging because it doesn't burn off. The silicon is a fix for the spooge but then it clogs the silencer like they said. Jetting correctly for the pipe and elevation is a must too.
If there is that much spooge, then your silencer packing is shot. Make sure you repack it, as Rich points out, for better performance and a quieter bike.
