2009 Street Glide Improvements over 2008

teleman001 · Apr 13th, 2009, 08:32 AM

Just a sidenote........there's been a lot of discussion about the need (or lack thereof) for fuel delivery modifications when altering the intake and or stock exhaust. This being my first injected bike, I'm in uncharted territory for the most part.

For what it's worth, I put on a set of "Rush" 2" slipons (which IMHO are perfect sounding for a bike with a fairing meaning they sound way better than stock, but are not obnoxious and allow you to hear the stereo with no problem) and a K&N stock replacement filter before butting the bike in hibernation for the winter.

The bike seems to run fine, but with warm weather approching I decided to ask the dealer if he would reccomend flashing the ECM or some other fuel mod. because I dont want the bike running too lean and running hot this summer.

He asked if I changed the stock backing plate and I said no. Then he said if I all I did was swap the filter and swap the mufflers, I didnt need to do anything to the fuel delivery system. Appearently the ECM will make the needed adjustments.

I can definately feel a bit more power with the changes, especially when pulling a good hill and I'm not one of those who has to have the fastest bike in the group, so the mods I've made suit me well.

Probably the best mod I've done wich I'd reccomend to anyone riding a touring bike is the floorboard extensions. My legs are way more comfortable and their cheap and simple to install.

Anyway, just thought I'd share this in hopes it will help somebody.

The swapping of the K&N for the original filter inside the stock housing really doesn't lean the mixture out so the dealer was partially correct in that it didn't give you much improvement as far as flow to effect the fuel mixture.
The stock 02 sensors will adjust somewhat but they will still bring you back to the original lean settings as dictated by EPA. An engine is basically an air pump so if you put more air/fuel in and better exhaust it will run more efficiently and produce better power.
I would suggest adding some fuel on your own to overcome the lean condition with a unit like the TFI and you will see a difference in the running. It's an easy install and you can set it to the way you want it to run unlike the factory settings.
Also as an FYI, replacing the filter with the K&N like you have done would have gotten much better results if you went to the stage 1 with the taller filter. The short K&N replacement in the stock air box only nets you the fact that you can clean and reuse the filter as opposed to replacing it at service time. The increased flow using that unit is marginal at best.

Thanks for the comeback. Forgive my ignorance.....but what is a TFI, how much$$ and where do I get one?

A TFI adjusts fuel on a fuel injected bike.

MANY topics on the TFI as well as where to get it with a discount here...

Question: I'm thinking of of adding the Screamin eagle Heavy Breather and SE slip-ons at the time of purchase. I noticed a lot of people here are using the Rush slip-ons. Is there a reason why I shouldn;t go with SE...i'm thinking it will keep the warranty...perhaps the Rush slip-ons don't keep the warranty?

Thanks again for your great help. I'm looking forward to doing more research on this site.

I put the SE heavy breath on mine SG but went with Rinehart slipons
great sound and only really loud when I get on it. Definitely have some power with this set up.

I agree! The more I ride it, the hotter it gets!

I added Rush slip-ons and a SE heavy breather when I bought my 09 SG and the dealer stated I did not need to do any mods as the 09 fuel managment can handle it. Time will tell but it seems to run great and it is not running too hot.

I'm now looking at the Reinhart slip-ons and SE Heavy breather for my 2009 SG. Will this allow me to hear the radio at cruise speed? Should I get the ECM reprogrammed? I'm lookin' at buying this bike on Friday, and am very excited.
