dude you have on your hands the two of the best, easiest to maintain and run motorcycles there are... besides flooding is there anything wrong with the 95 K75? how many miles on it? This is BMW that they wish they still made... so dependable... not even really broken in till you get 100,000 miles on it... some have ridden them for over 500,000 miles with minor maintenance. I envy you for your future fun of getting it up and running!
seriously check our www.bmwmoa.org the BMW motorcycle riders of america... dont know how much of the forums you can access without being a member, but there are plenty of old times there who relish talking guys through how to restore their BMW bikes... they are like bimmer fanatics only slightly different.
