Even though riding in the mountains here in Sunny Central Washington is a few months off, it may be time to take a look at what tools you are carrying in your pack and make some adjustments. We just returned from a trip to Sunny Central California to see some friends and do some riding. Overall the weather, riding and friends were great. But, the trip did not come off without a hitch. During our ride in the Mendocino Forest my bike decided to start having emotional issues. Loss of power, backfiring and nothing over 1/4 throttle. The check engine light came on, and started flashing a code. After pulling the tank, seat, etc. on the side of the trail and many colorful words I determined there wasn't anything to be done since it appears that a sensor decided it was time to call it quits. Fortunately, the bike would still start and run (sort of) so I limped the 14 or so miles back to the truck.
The experience got me thinking about what I carry in my pack. Like many people I struggle with the "how much is too much" debate. Over the years I have gone from carrying what seemed like a full tool-box including a lift, to just a small assortment of tools. However, the newer fuel injected bikes have some possible issues that may not have been potential problem on the older bikes. For example, on many modern bikes, if the battery is not connected they will not run properly or at all. In the old days, you really only needed to worry about a loose or broken wire in your ignition system. No so anymore; now you have to worry about your ignition and your fuel delivery systems and possibly the charging system as well.
Don't get me wrong, I am not lamenting about these "new fangled contraptions" . I think fuel injection is great for the most part. But as the technology we ride changes, we have to change our approach to understanding it and being as prepared as possible. So back to the issue of what to carry in your pack. The first step is to determine what tools are needed to remove your seat and tank. On most modern bikes this is pretty simple. On my WR450 it takes an 8 and 10 mm socket. Next, do you have the appropriate spark plug tool? This is one of those things you really should check in the comfort of your garage. Many bikes require an extra thin socket and/or a wobbly extension to get to the spark plug in the first place. So if you have just grabbed a spark plug socket that's not designed for a modern motorcycle there is a good chance it won't work and you don't want to figure that out on the side of the trail. Along with the appropriate spark plug socket and extension you may need some sort of tweezers to fish the plug out of the hole. Again do it in the garage first. Personally I carry a Tusk folding t-handle, 8, 10, 12 and 14 mm sockets, various allen keys (that fit the bolts on my bike), box-end wrenches of the same size, Tusk spark plug socket and extension, a small pair of pliers, a small phillips and a small flat screwdriver as well as a small knife. I also carry some zip-ties, extra spark plug, tire plugs, tube patch kit and small bicycle tire pump. It sounds like allot, but it all fits into a small pouch.
In addition to what I now carry I need to add a jumper wire with alligator clips and some electrical tape. That way if a wire breaks I have a way to by-pass it or make a repair. A simple thing like a ground wire breaking off can put your EFI bike into a panic and cause it to either not run at all or if you are lucky run really poorly, but still get you back to the truck.
A final thought; even though you cannot prevent things from breaking when you are on the trail, you can reduce the chances. Regular maintenance and inspection of your bike is the key to not needing tools. Oil changes and air filter maintenance go a long long way. Regularly inspect wire wiring, battery, brakes, bearings etc. I know, you might have to clean your bike but believe me, there is nothing more frustrating than dealing with a break-down in the middle of no-where, particularly if the problem could have been prevented with a little TLC.
Of course, you do have the option of jacking up the radiator cap and putting a new bike under it, but I am not sure how practical that is.
