Throttle adjustment

[BladeRider]

I just adjusted the throttle free play on the F4i... Now there is no dead zone at zero throttle... The bike is much more responsive now, and feels a lot smoother accelerating out of turns. To adjust, you just loosen the nut on the top cable coming from the throttle grip and then unscrew the long metal sleeve until there is no more free play, and then re-tighten the nut.

This one may be out of the "duh" category, but it took me a while to figure out! So, I thought I'd share for those who are slow like me :D

my throttle has lots of play last year. I was just too lazy to fix it. Bob(M_Y) tightened it up for me while we were standing around at a gas station. It has bee 10x better ever since. :thumb:

Something else you might want to fiddle around with on track days: up the idle speed to somewhere around 2k RPM or more.

why?

why?

Better low speed acceleration I assume.

I just heard it through the grape vine, I can't find the original talk about it, though.

My take -- when you shut the throttle and dis-engage the clutch when entering a turn, and then get back on it when exiting, you're motor isn't completely bogged down to low RPM's if you let your engine get down that low.

Then you're probably referring to idle adjustment, in addition to throttle adjustment. Throttle adjustment works only when the clutch is engaged. I can be wrong though :D

i'm new here and this info is very helpful to me. I'm gonna try do this on the weekend.

This adjustment has nothing to do with the performance of the motor.

What the largest thing people find with it is that if you have a lot of slack, when you roll off the gas, you are (even if you do not notice it) turning it all the way untill it stops. Then when you need to give it gas, there is a spot that has no resistance and it is very easy to turn. Then all of the sudden the cable gets tight and the gas hits like a brick.

If you take the slack out, then as soon as you turn your wrist, then the bike will respond to your input... This makes the bike respond smoother, but not make any more power.
