2008 XB12X, 9700 miles. When I twist the throttle I have to turn it about a quarter turn before I feel for gas. I'm mostly used to it but recently i let a friend ride it and he reminded me about it. Is this a simple fix at the throttle body or somewhere else? | ||

Joypipe, Do you have a shop manual yet? It's the best investment in your Uly you will ever make. Have you done a TPS reset lately? It's easily done on the '08 and newer Buells. Turn the key on. Do not start the bike. When the yellow light goes out turn the throttle gently three times from closed to open holding for a second or two at each position. Do not force the throttle against the stops just bring it to them. Turn off the ignition, wait 3 seconds, and start bike normally. This procedure will "teach" the ECM where the throttle is. If this doesn't eliminate the problem check your throttle cable for adjustment. The adjusters are on the side of the throttle body which can be accessed by removing the airbox assembly. Perform the TPS reset again after readjusting the cable. (Message edited by rwven on June 08, 2012) | ||

Sounds like loose throttle cables. Adjusters (at leas on my 2007) are up on the bars where the throttle cables come out of the throttle assembly. Be careful about getting them too tight, you can wear the cable and they can bind or make the engine race a full steering lock. | ||

Yep, throttle cable adjust emt first, TPS reset second. You have a throttle cable (opens the throttle) and an idle cable (closes it). They need to be adjusted together, by the book. If you do it wrong you could end up with slack like you have now, or worse, a throttle that doesn't close. Please, get or borrow a shop manual before messing with this! And when you're done adjusting...lube them too. | ||

Reepicheep, Yes, there are adjusters there also. I've not had to adjust mine yet in 41K miles, but I've seen the adjustment on the TB end while doing other work.... | ||

"Messing with this!" I found you need to get this "just right" for good throttle control. You should have a throttle that "snaps back" clean/easy to the stop point with enough slack, to the "bit point", to be comfy for your size hand and ride style. A good setup is key for low speed control as well. And do not forget to lock off the adjusters and check them every now and then as the can become loose over time/riding. | ||

I always set my throttles the same way. Adjust the pull(that opens the butterfly)till it will fully open the butterfly without smacking the limit too hard. You should be able to hear it hit the stop for full throttle. I back it off just a little so your barely hitting it. Lock it down. Now adjust the push so you have roughly an 1/8" of rotation of the throttle. You should be able to open it and let go and it shouldn't bind. It should snap shut. If it's binding then loosen the push a tad and try again. | ||

Thanks guys! I had shop manual and parts manual before I left the show room (almost). TPS resets accomplished here and there. (nice and easy on 2008) I'll read in there now on adjusting the throttle in the manual and use your advices to fill the gap! (Message edited by Joypipe on June 08, 2012) |
