Stock, it is properly tuned for city riding. You will notice on a stock Yamaha, the extra push of power, when the FI gives the bike the fuel it needs for HP. Most vehicles run lean in the mid-range (1.5-5.5k rpm).

Increasing it more, beyond the fuel efficient peak, will reduce fuel efficiency but increase HP.Īt full throttle it runs how it should run. Increasing the fuel will result in more fuel efficiency. It runs so lean that it actually runs below optimal parameters. I figure cutting the bottom half of the snorkel off, and just replacing the top snorkel part itself into the air box should still allow for decent airflow.Almost all vehicles in production by all manufacturers (cars, motorcycles, even airplanes) run lean by federal regulations on emissions. I've been told that this shouldn't be an issue unless riding in like monsoon downpour or something, but I know next time it rain, and I have to go somewhere, all I'm going to be thinking about, and worrying about is water getting into my engine through the intake. I ride my bike in the rain quite often, and I'm somewhat worried about water getting inside through the intake. I've contemplated doing the same type set up as you with my intake, but for a different reason. I've even tried listening for the air intake when I gas the bike, but the exhaust just drowns it out. I can't hear the intake suck sound over the Akrapovic Carbon w/o db killer.

The more free flowing MWR filter was added to compensate for the decreased air flow from adding the top half of the snorkel back into the equation. I did this because my bike was flashed for no snorkel, but I couldn't stand the suck sound the intake made with no snorkel. Whats a half snorkel?The snorkel extends quite a ways into the air box, so some folks have cut off the portion that actually extends into the air box and keep the L-shaped portion attached to the lid. I'm currently running a full Yoshi R77 carbon exhaust with stock air filter and snorkel removed, and ECU reflashed by Graves Motorsports. I'll accidentally slip a bit more throttle mindlessly and end up losing my upper balance for a hot second. It's also helped to give me a stronger drive out of corners in the canyons when it hits right as you're exiting the apex turn! It still catches me off guard from time to time when I'm being lazy on the bike. It's been super enjoyable and useful when you become expectant of the power. There were def jump points where the powerband would swell harder and feel like the bike caught a second wind haha. Not only did I notice the acceleration was alot more aggressive, but it was also not so linear as stock. The flash noticeably fixed a lot of the 'dead' spots in the RPM range as you twist the throttle. I absolutely noticed it in the butt dyno when I had my ECU reflash done too. To put it very simply, it seem like the power band isn't as linear as it was before the ECU flash, exhaust upgrade, and snorkel removal. I have very limited experience with street bikes so I hope I'm explaining this in an understandable way. I also have the snorkel removed now as well, so maybe this has something to do with it. I suspect that it has something to do with how the ECU is telling the bike to deliver air and fuel now. I never experienced this on the stock ECU setup. At first I noticed it very subtly, but earlier tonight the bike boosted so much that it literally threw me back a little bit. Its like it hits a certain rmp in 4th gear and the boosters just kick on. Then all of a sudden, and without changing the amount of throttle that I am giving, the bike noticeably picks up speed in a non-linear type of way. I'm talking just a slight throttle input. I'll go to accelerate by twisting the throttle and applying slightly more gas and the bike accelerates at what seems to be an expected force. So, there's been a few times when I'm chugging along at around 40 mph with the bike in 4th gear. I'll do my best to describe what I'm talking about here. I noticed something kinda strange almost right away, and I just want to check in and see if any of you all with a flashed ECU have experienced anything similar. I am more than satisfied with the results. I've been riding my FZ-07 for a couple days now with the new exhaust and flashed ECU.
