I am getting a lot of soot coming from my exhaust pipe. I noticed it on my garage floor where I park it. I also notice the soot on the tail pipe. The bike is a 2009 with 21000 Km on it. This has been happening for some time. I mentioned this to the dealer at the 20000 service was told this is normal because of the exhaust pipe configuration. I burn high test gas as recommended. Does this appear on any other Lt's.
