As luck would have it I was going to a BMW dealer with a friend of mine to have his first service done on his new r1250rt. Last weekend I did a little vigorous riding through some twisties keeping the bike at about 6-7k shifting between 3rd and 4th for about 8 miles. When the HD guys finally caught up with me they informed me I was pushing a little blue smoke out my left exhaust pipe. Well today as I was traveling to the dealer my bike turned into a full blown mosquito fogger as I came off the highway to a stop at the end of an exit. Thankfully the dealer was about a mile down the road from there. In any case has anyone had problems with the head gasket on a K1600 model as I have 40K on my bike. The dealer hasn't torn into it as of yet but it's about the only thing I can think of as the motor was still running smooth and didn't seem to drop a cylinder.
