I see that Kisan makes a number of accessories that will fit my bike... anyone use them? Pro's and Con's? Best place to buy them? Also, I remember that there were manufacturers of driving lights that attached to the front fork of BMers.... Anyone using them? Can you give me the names of the ones you know about, along with which ones are the best/worst.... and best place to buy them? Also, does everyone use the BMW oil/filter for maintenance, or are there other quality alternatives? Finally, best place to buy the oils/filters? Thanks so much!!
