Bought my CR last week, when I talk to the Harley sales people and Buell techs about the surging and bucking at lower rpm's they act like they've never heard of such a problem and that we should ride this bike different from the way we've ridden bikes for the last 30 yrs. I can accept this from the sales people but it worries me coming from a Buell tech, we trust them to know the answers and not be in the dark about known problems areas. Said all that to ask this, does the new re-flash on the ecm cure the 3,500 to 4,500 rpm bucking and surging for all the bikes with that problem? Is there a certain something (code of the flash) I can ask for to make sure I'm getting something that works, not something that's been in the computer for ages because they didn't know the new was out there. I am a bit paranoid after reading for several evenings all the post of similar problems like mine and for a long time no solutions. I copied, pasted and printed out everything I thought might be helpful to a tech who might be in the dark about some of the issues, but who knows they might be offended to give them something like that. I just want my bike to run right, the way I know is possible. MB | ||

Search the site for the word "flash". Use the search for the last 1000 hours. I did that last night and the specific flash numbers for the CR is in there. I did this last night for my R which is going into the dealer this morning for flash update and rear indicator. The code for the R is not the same as the CR. Happy hunting Xo. | ||

The flash does help some and some have modified the "noid" you can search for that one. However, I was told while in Milwaukee that trying to tune that specific rpm range it was found that they lost numbers in other rpm ranges with the exhaust that was designed. So..i was told they chose to leave it that way. That was coming from Gary Valine. | ||

I would go with what Buzzie says, and also add my own 1125 riding experience ... Limited as it is since I've only managed 650 miles on my 09R. But enough to comment. My bike was running the 131 version, and had a tiny amount of surge/buck if you were going quietly through a school zone - Not nearly enough to concern or annoy me. After updating to 142, it's almost unnoticeable. Would I trade 100% smoothness at sub-3.5K for the power in the mid/upper range? Not a chance! It rocks ... Mike | ||

It appears there is a disconnect of some sort between HD and their dealers when it comes to updates. I was in on Sunday and told I had the latest flash. I had the latest flash my dealer had, but it is not the latest flash. I spoke to the GM yesterday. He is aware of the problem and they now have the latest. I am going to get it on Saturday. My bike is very rough sub 3500. I just keep it above 3k and/or pull in the clutch. (Message edited by gotlime on November 11, 2009) | ||

Hmm, and I thought the 08's had the surging issues. Well except for mine and a bunch of others. My 08' fuels just fine from 2,000 rpm all the way up to red line. If I'm missing any HP, I sure can't tell. Maybe it's just because I'm too busy keeping the front end on the ground. Don't take the BS that "they are all that way" or "you will loose something if they change it down there". It ain't the truth. Later Neil S. | ||

Gotlime, I believe you're correct in saying that the latest available might not be the latest any particular dealer has. Once I told my dealer exactly what version I wanted (the latest & greatest R variant), they got it and put it on my bike. | ||

Latest CR flash is 152 Latest 09 R flash is 142. 08s use a different flash, I'n not sure of the number. The dealer needs to check your VIN on HD Net, the latest calibration for your bike will be listed. | ||
| Buzzie |
CR owners also need to consider ..if they have had the latest and greatest flash ..if its still got drivability concerns it may fall under the poor surface machining bulletin. | ||

Buzzie please list this poor machining bulletin and what is effected. | ||

On the crank rotor there is a sync gap, 2 teeth should be machined off. Some of the rotors still had a raised area where the teeth would be. This could fool the crank sensor and cause the surging/bucking. The flash had logic put in it to better detect this improper machined crank rotor. It should set the check engine light if the rotor is faulty. | ||

Okay interesting. I will print this for the dealer that is servicing my Faulty Stator and re flash. Do you think this contributed to the decel downshift engine cut off issue? (Message edited by freezerburn840 on November 11, 2009) | ||

Gotlime, do you have the 141 flash now? I went to my dealer and they could not get m3pus152 which is supposed to be the latest for the CR.. | ||
| Buzzie |
my bad...chevy got it right..i should have added more. i dont think would cause it to cut out i would believe more that faulty stator and charging issue would be more apt to do that. | ||
| Freezerburn840 |
Okay cool! Thanks for the help and info. guys. | ||

scott, no reason your dealer could not get you the 152 flash and IMO it is way Better then the 141. I they had to do was spend the 10 minutes it took to update there computer. | ||
| Scott0827 |
Cafe, thats what I figured!!! Thanks for the info... Ill try another dealer!! | ||

Converting it to R equivalents (142 vs 131) from the CR (152 vs 141), I would have to agree with Cafefun. Earlier posts of his saying he'd lost 'power wheelie' oomph when upgrading to 141 made me wonder what I might be missing on my R equivalent 131. The only '25 I had ridden was the one I bought, which came home with 131. But after upgrading to 142 (again, your CR = 152), I can verify it pulls noticeably harder. My front was popping up in spots it hadn't before, somewhat to my surprise. Smooth too! Mike | ||

FWIW, I took my CR to Gainesville harley to get it reflashed. They loaded the 141, this was 1 day after someone announced there was a 152. Anyway the bike had the 10z or 12z on it (still not sure if one of those is cr and one is r) and it was annoying to ride in the 4-5k range because of the surging. Cruising through gainesville was a headache and it was actually worse in lower gears with higher rpms. i could shift to 4th and ride under 4,000rpms and it was much more tolerable. Anyway the ride home was a huge improvement in the 4-5k range, not completely gone, but so much better that I can now ride in 1st gear and not worry about the bike surging going around corners. I will have to investigate if Ocala hd has the 152 or not. Cafe, are you going to dyno the bike with the new flash? |
