Why riding motorcycles with a backpack is a bad idea.

On May 12, 2015  I pulled my wife’s steed out of the garage to make sure it was in good shape for our trip this weekend (European Rider’s Rally).  With general maintenance items checked it was time to leave the stable. I glanced at the clock and realized I, of course, was running a little behind. I should have taken a little time to transfer my laptop and everyday work items into my messenger bag (which fits in Kelly’s f650gs twin side bag with a little coaxing). The backpack does not even come close to fitting in the side cases so I just put it on went on my merry way.

I have always been a little apprehensive about riding with a backpack strapped to my back. In theory if one were to run out of talent on the bike and go down on a tarmac scraping excursion, said backpack has the potential of exacerbating the stunt show (let us go ahead and call this what it is, foreshadowing). Going to work the bike stalled out a few times at stoplights I naturally attributed it to the gas going bad, it’s been sitting all winter. I get to work fine and go about my day. Finally at 1630, (4:30 pm for you non military speaking folk) I jump on my wife’s iron horse to begin the commute home.

No stalling this time, however, the RPMs kept dropping low so I decide to head to the gas station for some fresh fuel. Again nothing spectacular here, I pay without incident, start up the bike and begin the journey home. I turn out of the gas station and start down the road.  There is this fun little turn that I have to make so I prepare the lean.  I look, I press, and “I roll on the throttle”.  When I say “I roll on the throttle,” what I am really saying is the bike threw me to the ground! I think I was doing 40-ish mph. It happened really fast and I hit the ground hard, concrete does not give, period.

I have no idea why the bike went down on me. I think the steed might have seen a snake and threw me off. It was probably a rattler. I honestly do not blame the poor girl, as I share the same fear of snakes. In fact, if you ever want to see a Marine with sheer terror in their eyes bring a snake and place it in front of me. Actually, do not do this, my flight AND fight response will kick in. I’ll flight the living hell out of there when the snake is around, and I cannot be held responsible for what happens (read as fight response will most likely kick in) when I get back.  All you really need to know is, I have this innate ability to sense snakes and I fear them more than anything else in the world. This includes dodging mortar fire, but I digress.

Where were we, oh yes, Kelly’s f650gs saw a snake, or a clown, or heard me make one too many kitchen jokes, and threw me off out of fear/retaliation. While I was sliding in my mesh Kevlar suit, I noticed how blue the sky was, and was thinking to myself,

“Man I’m glad I’m an ATTGATT type of G…”

Audience (in unison)ATTGATT type of what?!

Before I could finish “Guy” I felt a hard tug on my left shoulder, the backpack had hit something and anchored itself. The left strap had a fierce grip on my shoulder, much harder than my mother did when I was goofing off at church. While this slowed my sliding considerably I could feel the pressure building up on my shoulder. As quickly as the whole incident started, it ended. I got up, hit the kill switch on the bike, and had a whole crew of construction guys asking if I was alright. If I was a single lady I would have been flattered, however as a guy my pride was crushed and I was much embarrassed.

Assuring everyone that I was fine I picked the bike up and placed it on the side stand. They kept telling me to sit down, one mentioned I must be in shock, and one pulled out his phone to call 911. The first guy asked me, “How in the hell are you moving?” I told him, “I’m fine; I’m an amateur stunt man.” then I waved my hand like Obi Wan Kenobi and said “He’s fine; there’s no need to get the police involved.” Looking back, they probably thought I had a concussion because of this one instance. After the thousandth reassurance that I was fine, not in shock, no concussion, and completely coherent I grabbed my bag, put it on my shoulders, started the bike and left.

After the adrenaline wore off my shoulder really started hurting and so did my collar bone. The day after the wreck I’m a little sore, no worse off than if a seat belt had been over my shoulder in a car wreck. Thinking back on it if I was going a little faster that bag could have broken my collarbone, separated my shoulder, or even broken some ribs. I have always worn a small camelback without worries but this incident has me wondering if even that is a good idea.

Learn from my mistakes; say no to backpacks while riding.

Let’s do a Positive – Negative Comparison

 


Positive

My gear worked

Wifey asked if I was alright without any mention of the damage done to her bike whatsoever (Keeper!)

Very Little Cosmetic damage to her bike

I learned in a somewhat slow and arguably a slightly controlled environment that a backpack is no bueno (controlled being not highway?)

Negative

I crashed my Wife’s Bike

I crashed my Wife’s Bike

I didn’t crash my bike.. I crashed my Wife’s Bike <sadface>

Shoulder is sore

Kelly’s bike is either really loyal to Kelly or is terrified of snakes and clowns

 

 

I think I’ll stop telling kitchen jokes in earshot just in case

All in all I’m fine. Glad the moto port worked so well. What really happened?  Well I stopped at a gas station so only guess is oil or anti freeze on the tires as I rolled in there.  Other than that, I have no freaking clue.

Feelers for 70’s 75/5 ; 75/6 ; 90/6

Fellow BMW motorcycle pundits,

Since networking with you guys has netted me a lot of cool loot/swag (i.e. Tire changer, Carb Synch tool, flashlights, t shirts, rock straps, etc.)  I figured I would ask y’all to keep an eye out for me.  I want a hack.  I’ve been weighing my options on what to get.  I would like the Ural 2wd but their reliability has always been questioned and that is supposed to be answered in the 2014 models but paying 16 G’s for a brand new motorcycle with sketchy reliability that max speed is 70 mph with a tailwind isn’t high on my priority.

So I’ve been researching and trying to locate a 1970’s era BMW motorcycle to add a hack to.  I’ve been specifically looking at the 75/6 or 90/6 due to the disc brake on the front and the prices are a little lower than the /5 (probably due to that nostalgic article in the MOA magazine).  But if I get a good deal on the 75/5 I’m not opposed to that either.

I am posting this on the forum because all of you are part of my network.  Maybe you know someone who has one in a barn looking for some TLC (As long as there are no throttle bodies to synch I can fix anything). Or perhaps you know someone who restores and sells them (Mike?).  Plus if push comes to shove I have a very reputable repair person down here in the Raleigh Area who I’ve talked to extensively on the bikes, the hacks, and advantages of both the BMW and Ural.

Feel free to hand out my contact info to anyone who has one and is looking to sell or feel free to contact me with the contact info of the individual.

Thanks Everyone.  Can’t wait to catch up at the upcoming rallies.

Caliper Sliding Pins (Brake Maintenance)

Just a heads up.  I now have 54K miles on my motorcycle and the Rear Caliper Has locked up on me.  Why is this?  Sit down and grab a soda, coffee, tea, and I’ll tell you how.

The GS adventure uses what is called a floating caliper design (this is a common design on motorcycles).  The caliper is attached to a bracket and that bracket is attached to the rear axle.  When the rider hits the brakes only one side of the caliper has pistons which push the pads against the rotor. While this is happening the caliper then slides on the pins so the other side is taunt against the rotor.  This push pull action is what allows us to slow down or come to a stop at the light.

So what happens when something goes wrong?

I’m glad you asked.  In my case the pins that the rear caliper slides on have become so corroded that the caliper no longer slides.  When I hit the brakes the piston pushes against the rotor and the caliper doesn’t slide over for the extra surface area.  I have roughly half of the breaking force.  This was caused by water (from river crossings) and Road Salt from winter riding making its way onto the pins.  The elements were able to attack the pins because apparently I had a Teeny weeny hole in the rubber boot, which didn’t become apparent until I sprayed penetrant in there and noticed it was bubbling out in the middle of the boot.

So what is the fix?
