I have a 2012 street glide. I have a problem sometimes that it stumbles when taking off, blow's back through the breather. it has died a couple of times. Most of the time it is good. I am thinking lean mixture. it also back fires at times when just changing gears. slightly


any ideas was considering a PCV but you have to eliminate the 02 sensors as the dealer I bought it from is die hard warranty folks

if the dealer wont honor warranty at all if you install a pc - ask him what he will go for. [id use tts or ssert rather than a pc anyway]

he might allow a ssert as long as the intake, air cleaner & exh is all left stock.

it is true that most tuners will technically void the warranty - but you may get some bend if it runs terrible.

if you are computer literate - tts is the best bet as you can put it to stone stock before a visit to the dealer - just remember to do it every time you think it might get read by the dealer.

Stumbling, stalling, and backfires through the intake are not normal, nor are they acceptable.  I'd suggest you inform your dealer of that fact and that you expect him to fix it under warranty.  Harley and it's dealers have been given a free ride on this stuff way too long, with customers spending large sums to fix lousy driveability with tuning devices and dyno tunes that can in fact void the warranty.  You don't have to accept it.  Contact Harley, if they don't step up then contact the NHTSA (stalling and stumbling are safety defects).

If your dealer wants to sell you a SEPST (Screamin' Eagle Pro Super Tuner) and tells you he will void your warranty if you buy some other device, I'd suggest you find another place to do business.  Modifying the bike with a SEPST is just as illegal as doing it with any other device, but it's funny how so many Harley dealers don't mind breaking the law and possibly voiding the warranty as long as they can make a profit on it.

This seems to be a common problem with '12 Street Glide.  Mine did that, to.  I plan on doing gradual modifications on my bike, and the fuel controller was one of the first things I bought.  I bought the new Cobra Powrpro.  That unit is a dirty word on this site, mainly because very few have any experience with it, but it really works well.  Retails for $600, but most I've talked to have paid less, as low as $480.

The good thing for you would be the fact that it's very easy to install and un-install, and it doesn't affect stock ECM.  If you need some warranty work done at the dealer, it would take 15mins to remove it, and the dealer couldn't void you warranty.

The difference in the performance alone was worth it to me.  But it also eliminated ALL the earlier annoyances like back firing, decel pop, heat, and throttle hesitation.

If you're in the north, contact Foster H-D in Tuscumbia. They may be able to help.

You did not say but have you made any mods to the bike?  If so that may be the cause of your driveability issues.  I had an '11 ruse and now have a '12 cuse7 and both were/are bone stock.  No driveability issues with either bike in stock configuration.  Something is wrong if your bike is stock, imo.

Are you using Rocket City HD?  If so, that may be your first problem.  You should have zero, none, nada problems like you're describing if the bike is bone stock.  If the dealer installed an exhaust system on the bike when you bought it, and told you the ECM would "adjust", they lied, or are ignorant, at best.  If it's bone stock, take it back to the dealer, or have them pick it up, document exactly what it's doing on the service order, and if they can't fix it, contact the MOCO and let them know what's happening with the bike and that your dealer doesn't seem to be able to fix the issue.  What your bike is doing can get you killed.  If they can't fix it, then Foster's HD, Rider's HD, or Heart of Dixie HD aren't that far away from Sand Mountain.  First thing to do is get the bike running right in stock configuration (unless you've made changes to the exhaust system).

If you want the bike to run better and have better drivability, then take it over to Rod's Performance in Hanceville and have him tune it with the TTS Mastertune...but save your stock configuration so you can put it back to stock if necessary for warranty work.  If you've got a Laptop, it's simple to load the stock map back into the ECM.

BTW, where on Sand Mountain do you live?  I often ride up that way from B'ham to visit the Guntersville area, eat at Catfish Cabin, or a combination of both.  There's also a pretty good BBQ place over near Scottsboro, just South of the bridge.  There's some nice riding in Northeast Alabama.  Russell Cave, Mentone, Desoto State Park, Desoto Falls, Little River Canyon, Lookout Mountain Hwy...

Between Scottsboro and Fort Payne. Yes they are a lot of good riding around me. Either is about the same distance.

They did a reflash and it helped a lot. so far no spitting through the breather and seems to have better power. Slight popping at times.
I will know tomorrow as I am riding all day.

thanks for the input, oh if I have any more service i will be using Thunder Creek form not on. They have always done good by me for many years.

Hey dirtdobber...I have a 2012 FLHTCUSE7 and I dont have any problems with backfiring or stumbling.  If you continue to have problems I would recommend Montgomery HD...I stopped there doing the fall and was impressed by some of the guys in the shop.  If you're ever in the Huntsville area shoot me a post.

From another 'Bama boy........
If the dealers can't get it right Rod's Performance will.  IMO he's the best.

The 96 in my 2007 Ultra did this bone stock (while cold) and the 110 in my 2011 Ultra did this bone stock (while cold) as well until both bikes had breathing modifications. Both bikes ran fine cold or hot after the mods/tuning.

I know the owner manuals for both years say to warm the bike up before riding but after almost dropping the bike in a turn because of a unanticipated studder I decided to make the changes.

[dirtdobber]

they did a reflash when I had it serviced, free of charge.
I have not had any stumbling since, no blow back through the filter either. Just some popping on decel...
I may do something to the exhaust later on, got to get over my purchase first LOL

The problems you are having are not normal.

Takes about 3 seconds for the fuel to build up pressure, wait until the light goes off before you try to start.  Also make sure you turn off the bike with the key NOT THE KILL SWITCH. 

Thunder Creek in Chattanooga has new management and a new VERY EXPERIENCED service manager.  They did the recall rebuild on my  07 SEUC last year.  Very satisfied.

Good Luck !

It is good to hear that the bike is better but I find it totally unacceptable for a new bike to not run perfectly. I understand all the guys telling you of the best private mechanics but they will charge you money to work on your bike. A new bike should require no money to run well. I have put SE tuners in both my bikes but I did not have to to make them run well. I did it as part of a performance package with pipes, cams and air filters, not to make a new bike run.

Stay after the dealer till he earns his money.
