Hotwiring motorcycles

ignition diagram for 2007 yamaha 225xt
Growing up I had a great fascination with computers. I spent most of my time programming, which meant that pretty much every other facet of my life suffered. Anything not tangentially related to programming took a back seat at best. I got by in school with the absolute minimum to get decent grades that would assuage my parents. It is therefore unsurprising that having taken 2 years of electronics as part of a computer science degree, I probably couldn’t unhook a car battery without seriously injuring myself and the car in the process. That is… until a lack of basic electronics kept me from properly enjoying a vacation. How hard could it be to hot wire a motorcycle? In the movies, thugs do it in 15 seconds flat, after having sprinted half way across town while dodging cars and cops.

I did what every computer savvy person would do. I spent a few hours googling everything from “Yamaha electrical diagram” and “how to hot wire a motorcycle”, to “how to steal a motorcycle”. Luckily I found the entire electrical diagram for one of the bikes. Unfortunately, I still couldn’t tell the difference between a resistor and a transistor. But I’d be damned if I couldn’t figure it out.

While Alejo slept, I came up to speed on ignition systems, starters, and spark plugs. Thankfully it wasn’t hard to figure out. All I needed was a short cable to bypass the key locking mechanism. When Alejo woke up, I brought him along for a short trek around town, asking for a “short wire to hot wire OUR motorcycles”. In retrospect, that probably wasn’t the best opener. No matter how we spun it, no one believed two homeless looking guys had brought two motorcycles across the state while leaving the keys behind. The local mechanic suspiciously agreed to give us a few short wires, with no advice or help whatsoever.

After only a morning of fiddling around (I never said I was a good thief!), I was able to find the right set of cables to bypass. Short cable in place, and voila– lights on, and the bike starts cranking. Unfortunately, Yano’s bike (which always gets experimented on first) takes a while to crank. While I’m cranking, I’m doing the dance of joy, which got quickly interrupted by Alejo screaming over the noise “hey smartass, if you ever get the bike to turn over, how the hell are you going to fill it up with gas without a key?”. Uhhhh… hmmm… “And if you manage to fuck up the ignition, I’ll kill you when the keys do arrive. I only get one week of vacation, unlike you nerds which work from home and seem to be in a permanent holiday every day.” Fair enough… I put the bike back together, and we drove around the park in the 4×4 pickup.

At this point I must add that Big Bend National Park is absolutely breathtaking, and is sadly one of the least visited parks in the US park system. The restaurant has been revamped to cater to a more gastronomically demanding crowd, and they’ve done away with the traditional hamburgers and chilli that plague campgrounds the world over. The food, though pricey for a state park ($10-$18/plate), is wonderfully succulent. The entrees are varied and are hands down better than most restaurants. There’s everything from fillet mignon, and smoked salmon, to grilled portabella mushrooms and peppers for the vegetarian crowd. The home-made soups are delicious, and the desserts leave you feeling as decadent as you’re used to.

So all in all, bikes or not, we’ve been having a blast. The views are spectacular and the food is great. Below is a link to the pictures so far, which may spoil the rest of the story, but are well worth seeing. We’re both pleasantly surprised. Big Bend has not left us wanting.

And as you can see, we eventually get our keys!
