fi on bikes

[rigtech514]

I want to put a 2006 DRZ front fork / Rim / Discs on the front of my 2005 KLR 650. I find that I'm riding a bit fast on very rough roads in Nevada, about 200 miles of dirt in a day fully loaded down for many days in a row. The stock front fork is just so weak for the riding were doing....Has anyone done this to thier bike? I know sagebruch Machine makes the crowns to fit this fork to a KLR 650...not sure where to get the sagebrush machine crowns...help

Not sure about mass air sensors, I think so. I think speed density lends itself to problems, and I'm sure speed density doesn't handle mods as well as mass air does I've owned two Triumps with EFI. First one was magic, right out of the box, second one had a bad ECU and needed to be replaced, then it too was magic. As far as tuning, Power Commanders work well on most bikes. 02 and later Triumphs use the "Tune Boy", basically allowing you to load different maps until you get one that works. The 99 I had was an easier to tune system. Techs could adjust the tune dynamically while using an exhaust gas analyzer. Neat stuff. EFI isn't the boogeyman any more. I've got a lot of faith in modern fuel injection. Here: http://www.motorcycleproject.com/motorcycle/text/inject.html Cheers CA Stu PS Both Triumphs are open loop, no O2 sensor.
