When you travel away from home and garage for weeks and months at a time, you had better be prepared for at least the common little failure issues that may arise, and sometimes bigger ones! On trips like this I have had to change a brake drum, swap a magneto, repair broken cables and repair flat tires. Needless to say the bike had considerable "garage preventative" before leaving home. For others I have changed K/S springs (as in more than one) lent the spare clutch pull lever under the K/S cover, inner tubes, tire pump and a myriad of other bits. I have only once had to be picked up from some 400 miles from home (Big end failure) and twice transported to a facility where I could make repairs. Broken (as in snapped in half) cam follower around 1000 miles from home and a G45 bearing retainer stripping the threads from the G2 plate about 600 miles from home. "Oh sir, I see you have your engine apart, could I possibly borrow your G2 plate for a few days."
It's always better and easier to do this at home, but if you are going travelling...............
