i just bought a 08 uly while sitting at a light idleling and when i go to take off it sounds like it back fires does this happen to any one else if not any ideas the bike has 600 miles on it now. | ||

I would start by resetting the TPS. Keith | ||

Keith, I thought the 2008 models didn't need to reset the TPS. If you are referring to the cough/hiccup coming of idle, my 2007 model did it from day one, as well. Tried everything - the only cure, for me at least, after trying everything i could think of (TPS resets, plugs, better fuel, etc..), was to fatten up the fuel map. John | ||

and all this would still be under warrenty?i hope | ||

I just got a 2008 too. It feels kinda doggy off the line but doesn't do anything odd other than that. On day #1 when I was to pick it up from the dealer, the plugs were fouled. I guess someone at the dealer didn't get the memo saying not to touch the throttle at startup. I would suggest that you bring it back to the dealer and tell them of your issue. Don't void the warranty by trying to fix it yourself. It might just be some simple thing like a partially fouled plug or slow sensor.... | ||

thank you !!! what kind of gas milage are u getting i can go about 130 miles so far on a tank is that good or bad i bought the bike on 5-5-08 and had 45 miles on it this is a pic without the bags and racks on it  (Message edited by back_woods_bueller on May 15, 2008) | ||

Congrats on the new Uly! Is that the X or XT? I got a new XT a couple of months ago. Very rarely it stumbles off idle and I suspect it's related to the quality of fuel (stale, ethanol, etc.). My bike's fuel economy is steadily improving. I wouldn't pay much attention to the mpg during break-in. You are getting close to 1st maintenance and could even do it early. If you have partially fouled plugs that will reduce or eliminate of some of the symptoms. There has been quite a bit of discussion on all the issues you mention. Just look around the Uly section. There is also a fuel economy spreadsheet link on several threads. 08Uly maintains it. Bob | ||
| Back_woods_bueller |
it is the xt model and as far as fuel i put highest octane from shell that they have from the start and i will keep looking thanx | ||
| Natexlh1000 |
Mine seems to go 140 before the light comes on and needs 3.6 gallons to fill it up. I think it will improve as it loosens up. My X1 didn't feel "right" until 8000 miles or so. (it's still kickin' at 83,000 miles now) | ||

i just bought a 08 uly while sitting at a light idleling I usually pull off to the side of the road before I make any large purchase decisions.  Congrats on the new ride! Tipsy | ||
| Chris_socal |
I had to have a wire repaired on my 08 at about 74 miles. The fuel pump started acting up and then the bike threw a low fuel light with a full tank. They fixed the wire and I haven't had any more related problems. -Chris | ||
| Back_woods_bueller |
lol tipsy yea my wife says i have a bad impulse buying problem | ||
| 08uly |
I have had mine cough or burp a few times but I usually attribute this to it not being fully warmed up. Fuel MPG is not as good on the 2008's as it was on the previous years. depending on your weight and riding style you are probably looking at 35 to 40 MPG average (see my data page). TPS reset not needed on 2008. Congrats & enjoy --- 08Uly Uly Data Page  | ||

Just in case you come from carburetors... DON'T BLIP. The EFI on these bikes HATES being blipped. Roll on gently and all will be well  Congrats on the XT. Love the black wheels, wish my X had them - they'd hide the brake dust and wet-road mung better than the silver. Of course I could just wash it...but what fun is that? | ||
| Curly |
+1 on the not blipping. mine would burp occasionally and would think i'm not blipping the throttle. but when i started paying attention i was blipping. old habits die hard. no problems since i stopped. | ||
| Tipsymcstagger |
With all due respect to those who say "don't blip," I think that's simply a cop-out. The problem is NOT blipping. The problem IS the engines (or fuel injections) inability to deal with blipping. Would you accept this condition as "okay" on any other vehicle that you own? Saying "don't blip" is tantamount to saying...."yeah, my house has no roof, but it's not a problem as long as it doesn't rain." The problem is not the rain. The problem is that the house has no roof. Should the house have a roof? Yes. But you're willing to deal with no roof because you've found you can get by as long as it doesn't rain. Should you be able to rev the engine? Would you be satisfied if the engine in your car backfired or fouled plugs if you gave it gas while sitting in neutral at a stoplight? I'm looking forward to learning how to utilize ECMSpy to tune the engine the way it should have been tuned from the factory...and then blipping to my hearts content. I won't be satisfied with a house with no roof. Tipsy (Message edited by tipsymcstagger on May 17, 2008) | ||

"...those who say "don't blip," I think that's simply a cop-out. The problem is NOT blipping.. The problem IS the engines (or fuel injections) inability to deal with blipping" +100 I asked myself, early on, would I accept a car that ran as poorly as mine did when I bought ... and would I be expected to re-map the fuel injection on my car because it ran poorly. No, not by a long shot! The HD tech's answer to me (at two different dealers) was "this is just how these things run" is nonsense and profoundly absurd. Just my 2 cents. John | ||

Tipsy and Johnboy, I guess you must still pump the gas pedal on your fuel injected cars to start them in the morning. How did you "fix" them so they actually start with that technique? Y'all apparently like to keep using 50s techniques. Whats next, drum brakes so you don't have to bleed the hydraulics?  GOTJ | ||
| Tipsymcstagger |
I think you misunderstand what I'm describing GOTJ. Maybe we're not correctly defining blipping? I don't touch the throttle when I start the bike. Nor do I think I should. Nor do I touch the throttle on any fuel injected product when starting. What I'm talking about is the ability (or lack there of) to rev the engine when it's not under load.

Tipsy, OK, I accept that but still, isn't blipping the throttle (to clean out a loaded up carb) the equivalent to pumping the gas pedal to richen the starting mixture of a carbed engine? Just an archaic technique/habit? So the fact that the Uly doesn't like blipping is the equivalent of a fuel injected car not liking the gas pedal pumped before starting. New techniques for new technology? GOTJ | ||

Revving the engine is fine. The EFI handles that with no problem. "Blipping", in my definition, is the quick snap of the throttle - not a roll, but a snap - typically used to make the 'vroom vroom' noise while at a light. If you're snapping the throttle open from idle, the TPS and other sensors/software can't react fast enough and the engine coughs. No amount of ECMSpy'ing is going to fix that; processor speed is processor speed. All a blip does is burn fuel and make the engine cough anyway. Roll on, ease the clutch out, and drive. The upside of it is, I no longer blip on my carb'd bikes either. Gas mileage is actually up, since I'm not shooting off the accelerator pump all the time. And just for the record, I don't rev the engines in my cars at lights either. I own carbureted stickshifts, EFI stickshifts, carbureted automatics and EFI automatics, turbocharged and naturally aspirated...the only time I'll build revs when I'm not moving is if I'm in the pre-stage lights at the dragstrip. | ||

What I'm talking about is the ability (or lack there of) to rev the engine when it's not under load. That is not necessarily what is meant by "blipping". People have had issues coming from a carburetor bike that does not want to idle smoothly, where they constantly have to keep blipping the throttle to keep it running and perhaps from fouling the plugs. When this "blipping" is done(usually by habit) the fuel injection doesn't handle the inputs well and if the engine is cold it is in run rich mode anyways, thus causing it to foul out. I have seen many bike riders sit a stop lights and for what ever reason( maybe they just like the sound), they just keep turning the throttle on an off and then as they take off they will blip it five or six times while clutching away, rather than turning the throttle smoothly accelerating once on take off. This activity is comparable to giving your home computer fifty or sixty commands at once and asking why it won't work correctly. Gotj has that point covered. I have not seen any F I Buells that cannot be revved with no load as long as they are warmed up a bit first. | ||

To me, owning a Uly is like dating a crazy girl who's great in bed. Fun, ooooh yeah, but then you're drivin' nuts by all of her crazy 'quirks'!  . | ||

My 06 XB12Scg with Buell Race kit has no qualms about being blipped. Have had the race kit on since new so I can't vouch for a purely stock set up. I would have to agree that a long stroke V-Twin would not take to being blipped like an over squared in-line 4. My Buell is a different animal than a four so I would not expect it to react the same way anyway. But I can blip with no problems. Maybe you all are trying to blip by grabbing a hand full of throttle which an in-line four would need. These V-twins only need a short twist to be blipped for any occasion such as down shifting or sounding cool at a red light. | ||
| Natexlh1000 |
My X1 doesn't care if it's being blipped either. I think the only real issue here is blipping the gas when the bike is cold as if the bike has an accelerator pump. | ||

Would you accept this condition as "okay" on any other vehicle that you own? My'86 Dodge Daytona had a similar behavior. It ran fine, but would NOT accept blipping. Go figure. So, yeah, I accepted it. Didn't like it, but had to accept it because there wasn't anyway to fix it. The Buell is my first fuelie bike and I immediately noticed the blip quirk and thought of the old Daytona. I think I've adjusted to the funky behavior. The most challenging situation is trying to smoothly roll on throttle after a turn - it has required a lot of practice to avoid the herky-jerkies. I would love it if this could be mapped out w/ the ECM, but can live with it if it can't. | ||

Ratbuell: "...If you're snapping the throttle open from idle, the TPS and other sensors/software can't react fast enough and the engine coughs. No amount of ECMSpy'ing is going to fix that; processor speed is processor speed...(etc)." Pure Rubbish! With all due respect, this is the kind of misinformation that for some reason seems to constantly get perpetuated here. And then some one else, who doesn't know any better, chimes in with "oh yeah, that's 100% right", because it seems like it makes sense - or should make sense. Then we are all supposed to buy into it.....right? Except for one thing, I all but eliminated the 'blip couch/hiccup' as well as the 'off-idle cough/hiccup' via ECMspy and a re-mapped EEPROM and fuel map that I did myself (OK it took me three months). How could that be - it's a 'processor speed' problem? If it was simply a "processor speed is processor speed" problem, then tweaking the EEPROM and fuel map would NOT have eliminated the problem. Why?... 'cause I didn't change the processor speed. Both the 'blip cough/hiccup' and the 'off-idle cough/hiccup' are symptoms that your fuel injection system is NOT working properly. Regardless of what Buell, or the dealers, or the tech guys tell you. I am NOT advocating blipping your throttle here - I don't constantly do it, either. But when you do, it should react properly - that's all. If it was a 'processor speed' problem then ALL Ulys everywhere (without exception) would manifest this behavior pattern, but they don't. Not all, but a lot do. If it was a processor speed problem then going to a race ECM and race can would not chance this symptom, but it has for some, not ALL. Treadmarks never changed his 'processor speed' to get rid of the 'off-idle cough/hiccup' problem he had. But he did get a customized EEPROM and fuel map. Look, believe what you want; tell yourself you're saving fuel, or whatever you have to tell yourself. I've been lied to by more that one Buell tech before about this condition. But then, they just want you to go away and live with it, in ignorant bliss that all Buells everywhere act like this...hmmmm. So here's what you need to do, just repeat .."It's just a Buell quirk, I need to learn to live with it"!....that's it ...now keep repeating it over and over and over again, until it sinks in. Any way, just my smart-a$$ed 2 cents. John **NOTE: Xopti remapped my EEPROM, I remapped my fuel map and used Treadmarks square idle, as well. . | ||

Or, if you don't like my and others explanation, just consider it part of the Uly "character." That usually dispenses with any further discussion. | ||
| Buford |
Do the 08's not come with an IAC motor? | ||
| Ratbuell |
I stand corrected. I still don't see the point of blipping though. And since I don't do it...my bone stock '06 has yet to cough at me (except when I rushed the tech and didn't get the TPS reset properly at a service), wet weather, dry weather, hot or cold. <shrug> | ||

Sorry to bring this thread back from the dead. But it seems this might explain the issue I'm having. When I'm actually riding, there's no problems at all. My X1 pulls the hardest and smoothest out of all my Buells. But while I can snap the throttle and produce a very satisfying bark with my M2 and XB12X, my X1 Lightning can't seem to blip off idle. It chokes up and (sometimes) makes a sort of pinging sound. This then: Revving the engine is fine. The EFI handles that with no problem. "Blipping", in my definition, is the quick snap of the throttle - not a roll, but a snap - typically used to make the 'vroom vroom' noise while at a light. If you're snapping the throttle open from idle, the TPS and other sensors/software can't react fast enough and the engine coughs. No amount of ECMSpy'ing is going to fix that; processor speed is processor speed. All a blip does is burn fuel and make the engine cough anyway. Roll on, ease the clutch out, and drive. seems like the explanation? If it's just a limitation of the primitive EFI, I can stop worrying about it and just not do it. But if there's something I can do to fix it, I would like to know. /edIt: ah, it has been discounted in this same thread. So maybe I should have someone look at my fuelmap again.
