Yamaha FZ1 with larger rear sprocket

At the 30,000 mile service the chain needed to be replaced. To my knowledge it had never been replaced. The stock FZ1 is geared quite high which makes it very subdued even when doing 80 MPH on the highway. This behavior is great for MPG and long highway trips but is not very engaging for…

ECUnleashed improved power and fuel economy?!

After one full gas tank after sending my 2006 Yamaha FZ1 ECU out to ECUnleashed for them to do their magic, I am a bit perplexed. The power delivery is so much smoother (Yay!) and increased, especially in lower gears and mid-range RPMs. Because of these traits I and because it’s like a new bike…

FZ1 Sprocket Exchange: Part II – The Ride

If I had to sum up the difference between the 17 tooth and 15 tooth front sprocket it would be something like: Say goodbye to the mundane daily commuter and hello to the twitchy street fighter. I have since reverted back to the 17 tooth front sprocket but the 15 was fun while it lasted.…
