08 Uly has been running poorly in mid range for a year. Reset the TPS several times by the book with no improvement. After reading here that the motor has to be at operating temp first I reset and the bike is running much better. Shop manual fails to mention the temp thing. Now on to the dreaded 20k rear rocker gasket replacement. | ||

While you're there do both front and rear gaskets and changes the plugs. This will be the easiest time there ever is. | ||

Got the PCVs, temp sensor, O2, and front mount. Rotated an XB years ago and recall it is a bit of a chore. | ||

20k rear rocker gasket replacement,is that a common issue? I read on here the TPS reset has to be done cold? | ||
| Griffmeister |
My gasket was leaking before 10K so yes, it has been an issue with some people. On the 08 and newer bikes it's not really a reset. All you are doing is zeroing the sensor,ie telling the ECU when the throttle is completely closed. The 06 and 07 bikes I believe needed to learn the full sensor range and had to be done hot. As the sensors changed over time this had to be done again and again. The newer bikes, being only a zero point, really should just have to be reset if the sensor is changed or disturbed in some other way. The ECU continually relearns the operating parameters as the bike is used. Maybe some other issue here. | ||

Knock on wood; neither of my '06 Uly's rocker boxes are leaking. | ||

Bike is on the lift. looking at the room available it looks like the motor will contact the front tire and even at ground contact the rear rocker will be obscured. I have the manual but would appreciate real world feedback. | ||

When the engine is rotated, the rear rocker box is in the position that the intake is in normally. Now you can access it from the top as well as some room at the sides. | ||

griff, Even on the '06-'07 (I have '06), you are only setting the closed point of the throttle position sensor. You just have to do it with teh diagnostic software of some kind. I've always done it hot because when you are done you need to reset idle anyway, and that is only accurate hot. there was a recent thread where someone (forget who) had a good explanation for why the TPS reset itself was also better done hot. Always done hot and never had an issue in about 4 or 5 resets I have done. | ||

Yea Griff you kind of have it backwards. Resetting the TPS / Zeroing the TPS are one in the same, when you do a TPS reset, you are backing it out to Zero, then pressing the reset button so that the bike knows where the zero point is. The bikes don't need the full motion of the TPS, just the zero point. The only reason they make you go wide open several times is to initiate the zeroing procedure. The reset doesn't matter if it is cold or hot, but it is recommended to do it hot as on the older bikes you need to adjust the idle, and it is harder to do when the bike is cold. The 08+ bikes are self controlling the idle, so it matters less on them. | ||

Just don't forget to back out the idle all the way before hitting that big reset button. It's easy to forget, and the bike runs terrible afterwards. DAMHIK.  | ||

right, you are setting the ZERO point of the throttle, not the idle position. Zero should mean as closed as it can be! With your voltage/TP showing, make sure you back off the idle until they read zero, and then a touch more to be safe. Record the starting position before you do the reset, so then you can reset it to that same value after the TPS reset, but before you attempt to start the bike. That should get you very close to the idle you had before, unless your TPS zero point was massively off or something. of course this is all for pre '08. | ||

Got the motor rotated and the valve covers off and was wondering if there any fasteners that should not receive never seize on re-install. Thanks. P.S. Mr Buell builds a good bike but anyone that thinks he walks on water has probably not got into an XB platform very far. | ||

Sorry for the rant, but for an old guy with iffy eyesight and fat fingers maintenance can be a bit of a challenge. Bikes done, all is good. | ||

Rant? You call that a rant? Why, my wife rants more than that if I forget to pick up the milk. You wanna hear a rant? You should have been in my garage when I was trying to get the primary gasket lined up after replacing my stator. That, sir, was a rant. I used up more F's than a junior high school penmanship teacher in a lifetime. The fricatives flew that day, my friend. Rant. Don't make me laugh. | ||

Skifast, You should have cut a bunch of 2" segments of allthread and screwed those into all the screw holes for the primary. Then put on the primary gasket onto those screws and then finally the primary cover. Then one at a time, replace those allthread studs with the primary cover screws. Would have saved a bunch of ranting. | ||

You should have cut a bunch of 2" segments of allthread Or use suitable bolts with the heads sawed off. Hopefully don't need a bunch; I'd think 4 or so would be sufficient. | ||
| Reepicheep |
You can do it simpler than that even... grab a wooden dowel rod (or something like it), a little smaller than the bolts. Cut it into sections about 1.5 times as long as the bolts. Sharpen one end in a pencil sharpener. Thread into the bolt holes in the primary. Works like the all thread / chopped bolts, but cheaper and easier. | ||
