Throttle Slop

[sparky3008]

It has been something that I have felt was a little extreme compared to other bikes I have owned. Reading a review the rider/reviewer mentioned the same thing so I realized it wasn't just me.

Can this "slop" be adjusted?

Thanks

Yes, minor adjustments are made on the cable itself, about 10" away from the throttle (grip) assembly.

Major adjustments are down where the cable meets the thottle valve (under the tank).

A 180 degree twist of the adjuster should bring it into reasonable range. Be sure to test your adjustment by starting the engine and turning your bars from side lock to side lock. listen for increase in RPM. If so, increase slack..

Yes it can, but be careful.

Over adjusting or tightening can result in error code 16...Throttle Position Sensor. The throttle needs the play to ensure it goes back to nominal and stays there. If a slide sticks, the sensor will think the throttle is open when it is not and will not send fuel to the injectors when you turn it over. The result is "no fire" and a 16 error code. Sitting the bike will usually correct this, but it may also result in a trip to the dealer.

Of the 2 adjustments any easy way to describe which one and in what direction it needs to turn? RTFM is possible as I do have it if that will describe it for me

Thanks for the replys

See, I learn something just about every time I come to this board. I don't have any slack in the cable, but now I know more about what to do should it ever be a problem.

You guys are just great!

Sparky, how much slop do you have? 1/8 turn of the grip? Less? Just curious as to what would constitute a major change versus a minor adjustment.

I didn't have really any problem until I put the new grips on. I really had to twist and turn on that thing and I think I must have actually stretched the cable. Measurement wise I would say a good 1/2 inch..

For any newbies who haven't done a throttle adjustment before--after you do the adjustment and BEFORE you ride off on the bike, remember to start the engine up and . turn the handlebars hard left and hard right to be sure you don't get a sudden throttle burst. Ask me how I know??

Guaranteed to raise your APF if it happens unexpectedly in the middle of fast turn.

When installing new grips, cut the old ones off with an exacto knife or razor blade (with care) instead of twisting them off. Use hair spray as a lubricant and the new grips will slide on real easy, then the hair spray dries and acts as an adhesive to hold the grips in place. Sounds hokey but it WORKS.
1/2 inch is too much play to adjust near the grip. You'll need to go under the tank, since the adjustment up by the grip is intended more for fine tuning. Normal grip play is 5mm (about .200") according to service manual, and you can go a bit less than that without any error. I run mine around 3mm (.125") and it works fine. Adjustment is almost self explanatory, you're basically loosening an adjustment lock nut, making adjustment (you'll know if you go the wrong way, since grip play will increase) and then tightening the lock nut so it holds its adjustment. If you've never raised the tank before just make sure you remove the plastic pieces on either side of the tank before raising it or they can get broken. There should be an article in the Tech section that describes lifting the tank, perhaps under TB sync or something similar.

Make sure you do this step FOR SURE, the importance of making this check can not be overstated!

Is there an echo in here? k:

Just bustin' your chops, Lee! You only mess up this adjustment once, eh??

Fastersilver--wow, did not know this! Sounds like you speak from experience as well?

Righty tighty, leftie loosey? :graduate:

Very funny, but actually up at the handle bar end right and left are sometimes how you look at it. You want the nut to go away from the handle bar so looking down on it would be to the right.

Made a world of differnce on control when going around turns for me
