throttle responce 2006 fjr

[jojofjr1300]

just had my bike services yesterday and asked the tech " why is the throttle responce so abrupt from closed throttle to open throttle"? the tech said" it's the way the fuel injection is set up at the factory, and nothing can be done, maybe a power commander could help". i have 13,000 miles on my bike since last july and this is the most annoying problem with the bike. is there a "YAMAHA" fix? is there any one in the orange county new york area that can bring it to to repair this problem. thank's for any assistance!

g2 throttle mod

throttle spring

Also look up info about the PCIII. It will help, it made a big difference on mine, but it is an 04. Others with an 06 have noticed a much smoother ride, and less herky jerky throttle control .

Remember to search!!! There is a plethora of info on this board as well as others.

Get the PCIII. Took some tinkering for me, but it's much better now. I have a 2006 AE.

JoJo,

You're correct about the abrupt throttle response. Most modern motorcycles have it, my ST-1300 had it as did my BMW-1150R. It's the CARB-08 standards (California Air Resources Board) and the Euro pollutions standards. The cars have the same problem, you should drive my Nissan pick up, just be careful when you put your foot down as the injectors open really quick. It's not as noticable because a car or truck weighs 4000 lbs and most have automatic transmissions. Bikes on the other hand weigh 1/8 of that and have manual transmissions and hand throttles. The problem is the throttle control programming, it turns the injectors off and on really quick so that when they are measuring CO2 etc they don't have to deal with roll-off and roll-on amounts. One of the things that happens is called "dry stack". In a carburetted bike there is a dribble of fuel that trickles after the butterflies close. This means that there is some residual vapors in the intake stacks that smooth out throttle response. Ok, so now you know why, but how to fix it?

The first thing I added was the G2 throttle cam. It's in the throttle grip and is made of plastic. When you twist the throttle the cable rolls over a cam inside that black Aluminum housing on your right grip. It's easy to take the grip apart and replace it with the G2 which is only about $65 shipping included. The new G2 replacement unit is billet machined Aluminum and is a first class component.https://shop.g2ergo.com/categoryNavigationD...hg?categoryId=2

The next thing you need to do is buy a PC-III and install that as well. It's about a 1 hour job if you drink a cup of coffee or an adult beverage. To do a really first class job I would do it on a Saturday morning and enjoy the experience, add a few tie wraps to secure things, you already have the URL for that. I bought mine from Bike Effects and they took good care of me.

The final mod you should do (but it's a personal preference) and that is the spring release (1 turn). This will give your wrist a break on long rides. I've done all of these and these will make your bike a totally mellow machine. There are plenty of posts on these mods so you won't starve for information or help.

Good luck!

It's true, until you install a Power Commander, all the other remedies (although they do help) are merely bandaids! The Power Commander makes the Gen-II FJR what it really should be!

Jeff at Bike Effects is my recommended source (use the FJR Forum discount, see above posting).

I agree with this but I also found that my dealer didn't really do a good throttle body sync (I don't believe he actually did one at all). The PCIII did help but did not cure the issue, until I did a good TB sync, then it almost disappeared. I don't believe you can totally eliminate it in all circumstances, but mine is about as close as you can get.

Fred H. Mod + G2 = decent

The pulley on the throttle body is part of the problem in addition to the EFI. It is set up so that it moves the throttle plates the most per unit grip rotation at low throttles. Makes for difficult throttle response. Havent tried the PCIII yet, but I am satisfied with these two mods.

BTW, the fred H mod involves taking a piece of solid 12ga house wire (romex) and forming it to fit into the groove in the throttle pulley to play with the cam profile. Works great and costs next to nothing.

You can get a bettere price on a PCIII at Morepower Ra0cing.com. They are getting $260 with free freight.

I would first try the throttle fix (CLICKY) I installed this on my '06 and it really dampened the quick throttle issue. At $60 this is cheap and an easy and quick install. :good:

If you want to further improve throttle and power curve, drop a few hundred on a Power Commander.

This should be required reading for all new FJR owners. The fixes here certainly tamed mine. Some of the problem is Yamaha but some unquestionably is EPA mandated and exists in most/all bikes but is more noticable on ones that have high torque and power at low rpm's. I am interested in seeing how Kaw handles it on the Concours.

I agree with Flyguy. Abrupt throttle transitions are here to stay, and have been here since FI came about. I overcame it with THROTTLE CONTROL. However, with the ultra stiff throttle on the FJR and one of the most abrupt transitions I've experienced, I couldn't 'tame' the beast on my test ride, but just brought my new baby home from the dealer, where I relaxed the main spring 1 turn, and it made all the difference in the world. Zero jerkiness by the time I got home, but yes, you have to become a master of throttle control. I don't think I'm going to do anything else, but glad to know there're 2 more cheap mods at my disposal: Fred and G2. Don't know which is, but will follow some links and do some research in the upcoming days. I just want to put some miles on the new toy so I can get the stupid break-in over. It's a long one, by the way: 1K miles. Geez. Later guys.
