I’m home from work sick. It’s probably Covid, but only because I’m not sure it’s possible to be sick with anything besides Covid anymore. Bad cold = Covid. Raging diarrhea = Covid. Brain tumor = Covid. Anyway, I’m so bored that I thought I’d write a lengthy post detailing how I ended up with two Ducati Monsters in my garage.
A little background: I bought in to the lies my mother told me about motorcycles. They’re dangerous. They’ll kill you. Only stupid people ride them. So I rode mountain bikes instead. At the end of 2014, I got a job with @Corban_White and he made me ride his dirt bike. Turns out all the things my mother told me are true, but she left out the part about how much fun they are. By 2017 I had my own YZ250. Did a bunch of riding in Moab and other fun places. Then I broke my collarbone at the dunes, got some fancy titanium bits installed and sold the bike. Shortly, after that @Corban_White found me a deal on a Husaberg FE450 that I couldn’t pass up and I was riding again. Even on the street, because the ‘Berg was plated. Been riding ever since. Illegally too, because I didn’t want to get my motorcycle endorsement on a 450.
Fast forward to March of 2022 when I found a KSL ad for a $500 2002 Ducati Monster 620. Been up two days. No pics and no favorites because he listed it in the Collectibles section (thank you, baby boomers for not fully understanding the interwebs). I got him to send me a couple pics and it’s a total basket case, but he had started reassembling it. Fresh powder coat on the frame and swingarm and he swears everything is there except the gas tank. So I grab a couple buddies and go pick it up on St. Patty’s Day. I mean, it’s a $500 Ducati! How could I retain my humanity and not buy it?
Well… as you’ve probably guessed by now there were more parts missing than just the fuel tank and it’s been one heck of an instructionless Lego set… and it’s still not running. But this brings us to the second Monster.
I spent a couple years of indentured servitude for the local church in Berlin, Germany. Germany is close to Italy, so there were a lot of Ducati’s running around. I kind of fell in love with them. Specifically, the 02 to 08 years of the Monster made me tingle on the inside. You know the feeling. That’s why I had to buy the basket case. It was the “one.”
Word got out among my friends that I’d purchased a Ducati. A friend of a friend says he wants to sell his Monster and asks if I want another. His just happens to be an 07 Monster S4Rs. If you don’t know what an S4Rs is, I will tell you. It’s the most baddest Monster ever made. (Technically the Monster 1200R has a few more horses, but it doesn’t have the “look” that I love). It’s what you end up with when you bolt all the nice parts from the Superbike onto that sexy Monster frame. 130 HP liquid cooled 998cc Testastretta motor. Öhlins suspension all the way around. Massive Brembo radial brakes. Lots of carbon. Forged Marchesini wheels also from the Superbike. It will do 155 MPH before it looses out to its total lack of aerodynamics. The same year of Superbike, with a nearly identical motor, will do over 170 thanks to the fairing and some different tuning.
Anyway, it’s the king of the Monsters and I quickly discover that it’s the “one” way more than my $500 620 is the “one.” So, I bought it too. I got a really good deal on it because it ran like crap. Wouldn’t idle, stumbled with any throttle input below 5k RPM. Huge PITA to ride because it stalled all the time. Once you got it above 5000 revs, it pulled like a freight train. It was truly terrifying. Perfect for a beginner bike, right?
Me being me, I can’t pay money to people who actually know what they’re doing to have the bike fixed…. that’s just silly. So I bought a black box and adapter cables from a guy in London and downloaded some kinda sketchy software from a guy in Germany to teach my laptop to speak Italian.
I knew the bike was running rich. It had fouled a lot of expensive spark plugs in very few miles. I knew it had a Tuneboy tune on it as well. My IAWDiag (sketchy software) program allowed me to reset my TPS and also discover that the fuel trim was at +110. Fuel trim can be adjusted from -128 to +128 with 0 supposedly being factory default. So my fuel trim was almost maxed out! I dropped it down to +10 and what do you know? The bike idled! And actually had decent low speed manners!
Each point of fuel trim (or CO trim as some call it) equals so many pico seconds of injector pulse width. I basically lowered the entire fuel map across the whole RPM range. So now low speed drivability is amazing, but that terrifying pull from 5k to redline is very muted. Felt like my 450. Sadness. I started adding fuel trim back in, but only made it to +20 before stalling became an issue again. The software I have doesn’t allow me to edit the actual fuel map, which clearly needs to happen, but at least it’s rideable now. Eventually, I’ll have to pay actual money to have it dyno tuned and a new fuel map made, since the Tuneboy map seems to be password protected (according to MotoStation).
