Anybody tried these? I found a set at a place called NIGHTRIDER.com - Motorcycle Performance Information .They cost 80.00. The tech i talked to told me they just plug in O2 sensor wire. They have resitors in line that tells ECU that engine is running lean.Will drop exhaust temps 40 deg.Also said put high flow air cleaner on , slip-ons and stock ECU will do the rest with the 02 inline enrichment devices on bike. I known sounds to good to be true dont it. But hey 80 bucks sounds better than 380.00 for a pc or other device.
