99 fzs600 lumpy idle, lumpy low speed

[Jamieg285]

Some of this maybe lack of experience on the bike.  I had similar issues with slower maneouvering when I started riding on a Fazer as the first bike ridden for over 17 years.  The throttle is sensitive, but you get better control with it the more you ride.

What condition is your chain, does it need adjusting?  I find a slack chain can affect slow riding where you are making small changes in throttle - this can also be helped by dragging the rear brake.

I also agree with increasing the idle speed. I ran with too low a level and found it much better a couple of hundred rpm higher.  You need to look at why the adjuster isn't working.
