I had done the Dynojet kit to the BSR before a Seattle to Sunnyside trip, otherwise the bike was stock. Seatlle to Sunnside is 180 miles one way. Odometer was at 750+ miles and it had its first oil change with Suzuki 10-40 dino at 500 miles. Time to finish the break-in was my thinking. We got on I-90 east and headed over Snoqualmie Pass (3,100 feet). My buddy was on his XR650L, perhaps comparable to a DRZ650. We stopped in Ellensberg to buy fuel, but before we tanked up, we did a few drag races. Bikes were dead even on several impromptu 1/8 mile drags. After fuel, we headed south along Manashtash Ridge, FS roads to Yakima, and onto Sunnyside. Seattle to Ellensburg is 110 miles, and we did the posted speed limit to get there. Leaving Sunnyside, we took the 'new' main freeway, which has a pretty decent grade to it. Time to test the DRZ! I slowly upped the pace until my buddy couldn't keep up. Speed was 70+, and true to Cameron's axiom; 'the only way an air cooled bike can shed more heat is to get hotter' rang true. The Honda lost efficiency, while the thermostat on the DRZ needed only to open a little further to maintain the pace. We made it from Sunnyside to Cle Ellum and refueled. This time I was going to really leave that Honda in the weeds! I was WFO whenever traffic permitted, but traffic was such that he never got that far behind. The mileage from Cle Ellum to the top of the pass is 48 miles, with an 800 foot elevation gain. At the top of the pass my bike started losing power. I had to switch the tank over to RES, so I had burned 2 gallons of gas going 48 miles, or 24MPG!!!!
He no longer has that big, heavy slow Honda. He now has a 2009 WR450. Naturally, my DRZ is much further along in the mod department too, which is good. A stock DRZ will never keep up with a WR450. I must be working my DRZ much harder than you could ever work a stock one, and it is no worse for the wear. It runs like a top!
