Juddering While Accelerating

Hi .. I am pretty new to the world of bikes.. well big bikes ! Bought myself a Vfr 2003 with 13000 miles and really enjoying it.

The only problem is i am finding it very difficult to live with while doing slow riding around town. The throttle to me takes alot of effort to use and when trying to make small imputs i end up jerking when i am trying really hard to ride smoothly. Is it me and in time i will get used to it or is there something i can do about it ? I end up having to slip the clutch just about all the time which cannot be right ?

I am planning to take it back to the dealer as they have been ever so helpful but any advice before i do would be great.

Thanks :)

Keep riding, you'll get used to the touchy throttle after a short time. Which leicester are you in?

Leicester as in uk england i see your not a million miles away :fing02:

Looks like its just a matter of practice then.. and lots of exersice for my wrists ;-)

Thanks for the relpy.

I've found a "throttle rocker", or "cramp buster" (basically the exact same thing) to be really helpful, both with the sensitivity and on long tours.

Thats a very clever but simple device !

Before i got the vfr i was warned that the bike can be hard on your wrists. I went for the first run out at the weekend which was a 200 mile round trip. On the way back my wrists were killing me and found it very difficult to ride smoothly. As i have said i am new to biking and this is my first big bike and a few months down the line i will probably be more then used to it.

Does anybody else suffer or suffered with bad wrists or do need to join the gym :blink:

Most move to heli bars, they reduce rear sweep and gain bar height, even offsets to the rear alittle, or use can raise stock clippons out of the detents and move forward which also helps comfort wise.

Life gets better around 4K rpm. Is the shuddering occuring at low revs?

02 sensor resistor replacement and maybe PAIR valve.....problem will disappear. if you want even more butter, pcIII

The stock fueling on the bike is very lean, and this makes for a twitchy throttle response at low speed / low rpm. You will become more smooth with the throttle as you get more time in on the bike, but there are a few things you can do to make it better. A Power Commander (PCIII USB) will allow you to adjust the fueling. You can download maps off of this site too. You will also need O2 eliminators with the PCIII.

I love my Throttle Rockers. I agree that they help steady the ride out.

check/replace the air filter.

Thanks for all the advice its all been a great help.

Ordered a throttle rocker and going to give the co sensor resistor replacement ago and see how i go from there.

No cost solutions...
1. Remove any slack in the throttle cable.
2. Make sure your chain is properly adjusted.
3. Develop a SMOOTH hand.

Purchased solutions...
4. Buy a Power Commander III using a better fuel map.
5. Install the O2 sensor eliminators that come with the PCIII.

You can help your wrists some by installing bar-risers, but the best way is to change the way you ride by getting your weight off of your hands and learning to hold yourself up with your torso.

BTW, welcome to the forum!

Again thankyou very much for all the advice only been on here for a few days and learnt so much already.

All being well in time i will get the hang of the bike and have even more fun then i am now :fing02:
