Just curious how the '08 engine changes are doing out in the field? Everything a-ok, or have there been some unforeseen problems with the new designs? (talking air-cooled only here, not 1125R) ~SM | ||

I havent gotten to ride it this year, but from the very few miles I did last year (including a 4 hour ride from ME to VT) it ran wonderfully. | ||

New owner of an '08 Lightning Long. Fan runs a little more then I would like, but I don't have anything to compare it to either. | ||

The only thing you really need to be concerned about is when it does not run. If it runs that means the "cooling system" is working properly. There are a lot of factors that contribute to the fan running: ambient temp, altitude, how hard you are running, what speed you are running, traffic etc...... Worst comes to worst, just tell your non-Buell friends that it's your "Supercharger"! Just enjoy the ride. Later Neil S. | ||

Heh, let's not turn this into another "the fan sucks" thread. That's already been discussed at length.  I was just curious if there had been any snags with the new changes, since there were several significant ones, particularly the changes in AFV calculation and TPS. ~SM (Message edited by Swordsman on April 10, 2008) | ||

Sword, The clutch cable retaining clip on my 08 has broken twice, allowing the clutch cable to contact the header pipe and melt. Both times the clutch cable has been replaced under warranty. It does have a slight stumble off idle if you try and take off under 2,000 rpms, but this is more of a minor annoyance than anything else. Other than that no problems to report in 6,000 miles... a few of which were rumbling through the twisties of North Georgia above 4,000 rpm. I have an ecmspy wizard that lives close by and may let him perform some minor tweaks. | ||

Hey paint, have you tried the TPS reset procedure for the 08's yet? If not that might help you out. 2008 Buell 1125R Throttle Position Sensor (TPS) Calibration (TPS Zero / TPS Reset) NOTE The Throttle Position Sensor Zero Procedure should be performed if the throttle position sensor or ECM are replaced or if the ECM has been recalibrated. To zero the TPS: 1. Set the Run/Stop switch to the Run position. 2. Turn the ignition key to the On position. 3. With the engine off, rotate the throttle grip from its closed throttle position to the wide-open throttle position and back to closed position three (3) times, holding the throttle grip against eash stop (open and closed) for one (1) full second. 4. Cycle the ignition key off and back on. At WOT? a properly calibrated TPS sensor will indicate 3.7 to 4.2 degrees volts?. I know it says 1125R, but this came from a service manual for the 08 XBs and it works for the 1125R also. | ||

I have the same complaint identical to paintshaker. the clip has broken on the bottom of mine plus the stumble of idle. i have 5500 miles on xb9sx. other then that the fan has only come on one time but it was only while hauling arse on the freeway. I guess i'll be calling the dealer when I get home bout getting that clip replaced. the only other complaint i have is the 9 also has the new crank sizing as the 12 but retains the same 7500 rpm rev.hmmm must be the valvetrain | ||

the stumbling bumbling engine is my only complaint about my 08 tt. coughs sputters backfires..... less than 1.5k miles. don't have time to get to the dealer yet. they'll for sure keep it 2 weeks and do 30 min of work on it...... (Message edited by spacecapsule1 on April 10, 2008) | ||

Space, dunno how the '08 is set up, but my '06 used to "hiccup" while cruising, and basically ran like crap. I rerouted the crank case vents so they no longer dumped back into the intake, and it did a world of good. Guess the gunk and bad gasses were throwing off the A/F settings. Since then, the bike has hiccuped only once or twice in the past year. Dunno if that'll help your problem any though. ~SM | ||

my 08 fan only comes on after the ignition is turned off and runs for about 4 mins...i have ridden in almost 90 degree weather and the fan never comes on until i shut it down.. anyone elses do this? | ||
| Swordsman |
Tsk Tsk! What did I say about fan talk? Bad wulf! Bad! No dinner for you! ~SM | ||
| Smiley1eye |
Dunno if this qualifies, but as far as I know, only one other guy is having this issue. http://www.badweatherbikers.com/buell/messages/384 2/341468.html?1207959801 | ||

VWFlat, The last time the put the clip back on, I also zip tied around the cable to the isolator as a safety in case the spring clip breaks again. Cat, Haven't tried zeroing the TPS as of yet. I am used to the stumble and just give it a bit more throttle from a start. Since I bought the 08 Bolt, the fan has only come on after shut down of the engine. Other than that, the engine runs great with no stumbles while in motion. It does pop under deceleration (more noticable with the Spec Ops pipe). I am not bothered by this, as long as the engine is not being harmed. | ||

i have read this stumble issue in several different post topics...i think is should be a sticky, until its resolved and not filed under denial...its a real and aggravating situation....keeping the revs up is not the answer, unless you sit at a traffic light with the throttle at 3k rpm...i imagine the problem will remain until some kind of moco download comes out.. on the other hand, if you are a regular on the harley forum, the 07 and some 08 touring bike owners are up to their butts in alligators with serious engine and tranny problems, that make the stumble look trivial...now that ive got almost 2k miles on my bike, hiccuping has become a bit less, but the surging in lower gears has become more aggravating... just call me the "surgin general"...ive done the tps proceedure several times and nada....all my buells have been start and ride, until the 08...if you try to ride it cold, it will stall...not fun, if you are leaned over, making your turn onto the state highway...the only reason that i brought up the dreaded fan thingy, is trying to find a common demominator for the bikes that are infected... | ||
| Spacecapsule1 |
hey surgin general......... yep............ i've experienced the "mid-turn stall" on numerous occasions. Now i refuse to ride until the bike has warmed up for a few minutes. Even then it still runs like dookie. Very frustrating. Swordsman, I haven't done the re-route. I was hoping I could just ride my new bike and enjoy it rather than tinkering with it all the time like I had to do with my blast. I'll look into it I suppose...... | ||
| Spdkls |
i haven't noticed any problems accept during startup. just have to let the bike warm up. mine pipe also pops on decel, not to worried about that, until i see flames coming out the intake. only issue i have is the amount of bad gas we are getting around here. i filled up on base about 3 weeks ago and got about 120 until my light came on. went to a better station and got about 150. i didn't do too many sprints as i was experimenting. so that could be another issue. might start investing in some toluene and make some octane booster. cheaper than buying straight-up booster and better. | ||

you would expect stuff like this from a carb, because its the nature of the beast and you give it choke accordingly (but i still like carbs)...however with efi on a brand new bike that you ride everyday like i do, you shouldnt have to do a rain dance and say 3 "hail mary's" in order to ride on!.. my X-1 and S-3, you turn the key and enjoy the ride..actually i went thru this exact same scenario with my 06 streetrod...i lived with it for 15k miles and the factory never came out with a cure, even though it was well documented as a problem on the v-rod forum...finally i put a SE race tuner on it and it ran like a champ...

'08 XT - 40 miles (yes, 40 miles) - failed oxygen sensor.  On the other hand, the upgrades to the '08 cooling system seem to reduce the amount of fan time. So that's a plus.... | ||
| Spacecapsule1 |
I'll second the reduced fan time. i really haven't noticed it running while i'm riding...... | ||

I have an 05 XB and the surging/stalling/stumble/pinging issues have been around since the intro of the XB back in 03. One would think after five or so years this would have been corrected by now. It's not like the internal combustion engine and electronic fuel injection are new inventions. | ||

I'm starting to hear a bit more of this...it does seem that the 08's don't quite have the low end punch that the pre 08's have....A good freind of mine who is the editor of 2wheelfreaks called me yesterday after putting some miles on an 08 uly.....And asked me about it....So only thing i can figure maybe it's the mapping with the new ecm...????? Hopefully Al at American sportbike will come up with a new map.... |
