TWITCHY THROTTLE

[BRILLOMT07]

I'm 66 years old and have been a dirt biker since 1958,never ridden on the street.Due to a non-bike related knee injury,I can't ride off-road anymore.I shopped around and bought a 2018 mt-07.I'm a speed limit person and don't need a hot rod,just something fun to cruise around with.I noticed the throttle was twitchy when I took one on a test ride but I figured it was something that was my problem and that I could adjust to.But this is not a throttle but more of a toggle switch.After reading rider's post's I now realize that this is just the way the bike is.Why would Yamaha produce a bike with such a garbage throttle?I have no desire to ride it this way.I've read the term re-flashing that will cure the problem.Is this covered under warranty?If not,how much will it cost to get it fixed?And where do I take it?I live in Puyallup,Wa.I have to take the riders skill test to get my bike endorsment,riding around cones in 1st and 2nd gear and that will be impossible without the tester thinking I'm drunk!!Any advice or solutions would be greatly appreciated.Thanks much.

Congratulations on you new ride. It is a fun bike to ride and does have it's quirks.

 

2WDW (2 Wheel Dynoworks) can flash your ECU and they are a forum partner here. You would need to ship your ECU to them. While I don't have any personal experience using them, from posts I've read here they do great work and have a fast turn around.

 

There is also an alternative, if offered in WA, which is to take a rider safety course in order to get your endorsement. While I understand you have a vast amount of experience of off road skill, a rider course will help with the transition to the street. There are beginner and experienced rider courses offered by the Motorcycle Safety Foundation (MSF). As a rider coach, I have had many students with experience take either one. Go to MSF-USA.ORG to see if there are classes offered near you. Usually, when you complete the course after riding all the exercises and passing both a knowledge test and a skills evaluation, a student rider will receive a license waiver card to take to their DMV to get their endorsement. Check local listings for permit holding requirements and if such a card is accepted by your state.

 

If there are no MSF courses offered, try a nearby Harley Davidson dealer and see if they offer the Harley Davidson Riding Academy classes.  It's a great program.

 

Advantages to taking an beginner course are that, in most cases (again, check local listings), you use the course providers machine. It is a about a 2.5 to 3 day course, usually over the weekend, which might not work for some people. The Experienced rider course is usually covered in a day or less depending on class size and how well the class progresses and the student uses their own bike. The advantage here is you learn more about how your bike handles and reacts to input from you.

 

As a former motocross racer and a motorcyclist with over 30 years experience and a rider coach for the past 9 years, I can say that when I trained to be a rider coach, it helped with how I ride on the street. Providing exercise demo's for the students also helps improve my skills as I am doing what the same things they are learning.

 

Apologies for the long post.  Enjoy your new ride.

3 things

 

1. The throttle twitchiness people describe on here is pretty much at mid to high rpms due to injector shut off. If you feel it’s going to hurt you in a test where you’ll never get above 4000 rpms then you have very poor throttle smoothness in your wrist. It’s not uncommon coming from dirt bikes to have rough throttle control, it’s a different style of throttle control on the dirt, almost opposite in fact. 

 

2. Check your throttle cable slop and make sure it’s as tight as can be without dragging at full bar lock. On dirt bike we tend to run a bit of slop to prevent whisky throttle on street bikes it’s not needed. 

 

 

 

3. Maybe your bike is one in a million and has a legitimate problem but I doubt it. 

 

Bonus. People on forums will blow things out of  proportion when complaining about something. It’s just how things work when trying to discride something in text but really want to get the point across. A small problem which can be escalated with poor skill will quickly be dubbed a huge problem because most people start with poor skill or control when trying something new. Tighten that throttle slop and do a little practice to be smoother I’m sure it’ll help.

Welcome and congrats on your new bike! You asked if it's covered under warranty. I don't personally have one, I have an Dobeck EJK fuel controller instead which smooths out the throttle also but it doesn't do as much as a flash dune does, like get rid of the problem with the fuel shut-off, which can be a big problem. (Sorry, I have to mention this so you're aware of the problem) That's my #1 gripe with this bike, it's caused my bike to instantly go dead on me when taking off a number of times because I lightly blipped the throttle while letting the clutch out. That's a no-no with this bike, the bike shuts off the fuel after the blip so the bike dies because it doesn't get enough fuel while letting the clutch out. It's almost like popping a clutch sitting still without giving it any fuel, it doesn't buck but it dies instantly. A couple years back when no one knew what the problem was they blamed seasoned riders for bad clutch/throttle, it's been proven since that they were wrong.

 

It's caused me to almost drop the bike once and it could put you dead still in front of oncoming vehicles while you're trying to start it. Not a feature you want in your bike. 

I highly recommend the 2wheeldynoworks flash tune instead for that reason alone. Read up on it, it does other nice things as well without making it a 'hot-rod', although this bike kinda is one from the factory but only if you make it happen. (rider option) Sorry this was so long but I feel it had to be said. It think it should be for all people buying this bike since it can be a hazard or has Yamaha corrected the problem with the 18's? Anyone? Have fun & stay frosty!

Thanks much to everyone who responded to my problem.I noticed as soon as I left the dealer that there was a little slack in the throttle,but I didn't think anything of it because that's the way I've alway's kept my dirt bikes.I adjusted it so at full lock in both directions it's idling about 500 rpm's above stock.When I got back from the dealer and was going through the bike I found that the chain had almost 3''of slack.So much for dealer prep.I adjusted it so it has about 2''of slack now.I haven't had a chance to ride it since the adjustments,but I'll let ya all know how it work's out.Like you all said,throttle control is totally differant than on a dirt bike,so I'll put a couple hundred miles on it before I start crying about anything.Also,to me,sound is half the enjoyment on riding any bikes.On my MT07,the only sound I can hear is the engine and gearbox.My regular mount for the last 28 years has been a 1984 Yamaha TT600K.In rainy season I ran a straight pipe and megaphone,in the dry season I ran a spark arrester.Easily the sweetest and violent sounding bike I've ever heard.I know I could never get the MT to sound like that but would it hurt the engine any if I ran it without the baffle in it?I'm totally knew to these computer bikes,back pressures and all.I wouldn't care if I lost a little power or anything,as long as I could hear it.Thank's much to everyone who's listening.I think I would be totally lost without You're guy's experience and feedback.I'll let you know how the adjustments worked out.   Brillo.

Holy crap someone on a forum who can read some advice that doesn’t directly reinforce their original complaint and reflected on what they are actually feeling. This is obviously not the Gixxer forum 

 

ive adjusted my chain twice in the first 500 miles, seems to have stabilized now.

It's not going to hurt your engine but the sound won't be anywhere near approaching, 'violent", either. I had a Super Trapp on an old XL500 (thumper) that sounded pretty effing violent also, it was so raspy and loud. Talk about a head turner!

[RojoRacing]

I did the drill 6 holes in the stock exhaust just to have a reference of what others are doing, I already had a Yosh R77 in the mail at the time. What I found was drilling the holes gave it 20% more bass below 4000rpms so it sounds cool in your driveway and at stoplights but once you’re rolling you don’t  really hear a different. 

 

Then I installed the Yosh and let’s just say I’ve yet to see a YouTube video do the sound difference justice. It’s like a cross between an old school strait pipe flat track bike and a Ducati with proper exhaust . I swear if you just loosened some bolts on the MT to simulate the sound of a dry clutch you fool everyone who hears the bike till they turn to see it not a Ducati. The funny thing is with the R77 the gains in sound seem to slightly fall off as your raise in RPMs which is not a bad thing at all. The best way to discribe it is when you at idle is sound great but as soon as you crack it on to leave a stop it’s like holy F**K this things sounds mean.  Then as you get up to hwy speeds the sound smooths out just enough that you don’t get annoyed with that overly load droning sound when you sit at a constant RPM. 

 

Only downside is although for a full pipe with carbon can at $600 is not a bad deal at all it’s will require you to reflash your ecu which can cost you another $200-300 so you need to include that in the cost. I still think it’s totally worth it because you can’t put a price on a bike that sounds so nice it makes you smile each time to crack open the throttle.

Again, please stop creating duplicate threads. You started this thread in general discussion. And then you started another twitchy throttle thread in new member introductions board. 

Please, go back and post in the threads that you already started, only create a new thread if you have a whole new topic to talk about.  Im merging this topic with your other twitchy throttle thread now.

I plan on taking the test this Wednesday , i luv my fz and riding it has been a blast but i started tryN to practice tight intricate maneuvers and i started to stress the same thing. My plan is to flash my ecu but would have been slick to have done it prior.
