Let me start by saying “I am a believer!”. I took the bike out for the first time with the Ivan’s Performance Fuel Cut Eliminator installed and was rather pleased with the results.

Since I wasn’t going to be riding on the highway much I opted not to wear earplugs which automatically makes one’s experience more visceral. It was wonderful to hear the roar of the engine even through my stock exhaust.

I went on a variation of my standard short circuit and found myself gaining in confidence due to the increased smoothness and predictability of my throttle roll-ons mid corner. Before the bike was rather skittish and jerky when rolling on the throttle, especially above 5k rpm. This forced me to run in a higher gear in order to keep the revs low.

With the FCE installed I found that I could round a corner in any gear I wanted, at any rpm I wanted, and still have a smooth-as-butter roll-on post apex. Riding became much more fun because I felt I could push it more and lean it over more with increased safety. I wasn’t as worried about my rear end slipping out from under me.

The price is a bit steep ($200) but not by much and Ivan’s seem like good people to work with. Installation was easy enough if a bit tedious due to the number of screws involved. (see previous post)

I would highly recommend the Ivan’s Performance FCE to anyone who has a 2006 Yamaha FZ1. As the years went on, I think Yamaha got better at masking the effects of the mandated fuel cut. I’m happy I installed it and look forward to further confidence in my riding.

—UPDATE—
I reread Ivan’s page and he states that this will help any fuel injected FZ1 (years 2006-2010) and not only makes roll-ons smoother but increases mid range power. I suppose I may have felt a difference in mid range power but I can only attest to the smoothness of the roll-ons mid corner.
