![]() ![]() I'm not aware of a quickshifter with a blip function for the 07, because it has a throttle cables rather than drive by wire. It functions by cutting the fuel rather than the spark, when sufficient pressure is applied to the shifter, and it functions flawlessly when adjusted for timing and pressure. The quick-shifter I use (aRacer) doesn't include a blip function for downshifts it only works for up shifts. ![]() I do it sometimes on the track but can't imagine any reason to do it on the street. Clutchless downshifting is possible but only when revs and load on the gearbox are low, to avoid gearbox damage and upsetting the balance of the bike. Undercutting is an effective modification but it requires complete disassembly of the motor and it isn't cheap.Ĭlutchless up shifting with constant mesh gearboxes, like the 07 and every other motorcycle I've owned, is easy and doesn't beatup the dogs as long as you fully unload the gears and don't rush things. This has led to some issues with race bikes generating more than stock hp the 4th to 5th upshift in particular from what I've heard. If you are comfortable with the throttle response of your bike and don't have excessive popping from exhaust, then I wouldn't worry about it and just enjoy.Ģ020 and prior gears are not undercut from Yamaha. Mine had this quirk and it would happen 3-4 times a year usually while waiting for a stop light to change or when just leaving the light. I do know early on (2015-2016) some posters complained about stalling issues with their bikes, while most never experienced this problem. Maybe some exhausts work better with a tune than others or maybe there are some minor variations between the bikes. I don't have a clue why the tune works for some and not others. The personality of the bike is still there just a little more refined. It doesn't and I wouldn't want that anyway. I'm not going to go over the top and say it feels like a whole new bike. In my case it feels like a well carbureted bike now. It reduced the engine braking to what I consider to be a reasonable amount, it also smoothed out the off/on throttle transition to a more comfortable level. I wasn't as much looking for more power as much as I was looking to smooth out the power band and the tune did exactly what I wanted. I have Akra Ti exhaust and the tune made for a solid improvement on my bike. ![]() Has anyone here had one of these apart and looked at the dogs? With undercut dogs you can be sloppier with the shifts and the gears tend to pull themselves into engagement if you don't get them all the way together. For square cut gears I like to pull in the clutch, shift cleanly, and hold the shift lever until I let the clutch back out. Eventually you can wear though a snap ring and have to disassemble the transmission to fix it, while hoping nothing else got damaged. You can get gears engaged but not quite fully that way, and put undue forces on snap rings. If we have square cut dogs, then I don't recommend clutchless shifting as a matter of habit. Photos seem to show square cut dogs, but Yamaha says the 2021 model has different angles on the dogs to make it shift smoother, which implies the 2020 and earlier version has more undercutting than the 2021. I've been trying to figure out if the transmission gear dogs are undercut on these bikes. Once it opens go to ECU Modules > PC Import > Extract Fuel Maps from file and select the file you downloaded from Dynojet.You know. If you have a stock exhaust download map 22-065-005. Looks like you need help clarifying how to set this up. I may call 2WDW to see what solution they may have. I called FTECU and they told me the unrestricted map would work, I highly doubt it will be sufficient to handle the increased air flow of the DNA lid swap. I wish I wouldn’t have pulled the trigger on the FTEcu datalink kit. There are some Fz-07 files but they are like 14-16 model years. I have been all over the power commander download files and there are no MT-07 files other than stick for 17-19. ![]()
