I just bought a 1999 road glide fuel injected. The bike will fire up easy when it's cold. It seems about a minute after starting it will stall and the warmer it gets the more is doesn't want to idle. This is my first Harley and could use some tips,thanks.

Is it throwing any codes ? I think back then you got to count light flashes.

A friend had a 1998 Road Glide and his did the same thing. It turned out to be an intake leak between the induction module, and the manifold. Things got a little brittle with age. New intake seals fixed it right up. Cost less than 10 bucks.

To check to see if this is the problem, carefully spray a little brake cleaner on the manifold, making sure none gets in the intake. If the bike suddenly dies, you have a leak. Have someone keep the throttle a little above idle while you do this.

A few times I've gotten bad gas (with water) and the engine wouldn't idle. I was skeptical when the dealer told me to use SeaFoam, however, it ran better immediately. Hope this may be all that's wrong with yours. Good Luck

So should I check around the air filter for this leak?

Behind the air filter, you will see a Y shaped tube. The induction module splits into the front and rear jug. That's where they leak. There are 2 seals

Look at item number 5 in the picture. That's where you want to shoot a little blast of brake cleaner. If there is a leak the engine will shut down really quick.

Hi Aceswild; I have the SERG '01 with the Magneti Marelli EFI. I have had this bike for a couple of years and gotten used to it's "eccentric behavior". The local MoCo mechanic just gave me a smirk when I asked him to fix it. I was told that there are very few mechanics left who really knows how to do it or care to do it...
In 2002 (IIRC) MoCo switched to Delphi-injectors for more than one reason obviously.

Anyhow, apart from the slightly irritating start-up procedure, the bike performs well even with the quirky Italian EFI. I never had any trouble going for long trips; engine revving with ease and performing like an EFI should. After a couple of miles the bike will idle without problem although sometimes it drops to "parade-mode" (nobody told it that this is NOT a feature on this model! :D

I know of course that a lot of people have chucked the M&M and put in a Mikuni carb. instead. But I am not going to such drastic means as long as the EFI works at full throttle without a glitch.

BUT if you want to spend the money; or to qoute Zipper's performance products: «Stop cussing that early EFI system, just replace it!». It's a very nice product but it will cost you about US$ 2500,00.

Just my 2c.

Fuel lines inside the tank could be leaking, and MM pressure regulators are known culprits as well. Many find throwing $$ at it doesn't make it run better, why HD went with Delphi, and many owners change over to a carb.

I too have a 99. I also had warm idle issues. I had leaking intake seals as others advised you to check .
However I fixed my idle issues by following this you tube video. The screws holding the Throttle position sensor still had the glue in them from the factory so I knew it had never been touched. I do recommend a long torx screwdriver I don't recall the size. It should start and cold fast idle for a few minutes around 1500 rpm and then drop down to 900-1000 warm idle. What this video shows is how to adjust the throttle position sensor. The sensor sends a signal (number) to the ECM so that the ECM knows what position the throttle plates are in. The computer knows a number which he tells in the video but escapes me at this time what "closed" is. Warning- when adjusting this it's the most sensitive SOB in the world. So sensitive that just tightening the screws back down will change the reading. It took several tries to get it just where I wanted it. Use patience.

I've read that its best to start it up and not touch the throttle until after it drops down to warm idle.

Best of luck. it's not as bad as some make the early system out to be, or it hasn't been my experience yet.

Nice video, going to try this with my 99 Ultra. Hopefully get it back up to the 45-50 MPG's. Aside from the idle, I have not had any problems other than a couple of injectors that went bad.

Thanks for the suggestion, I took my bike to the dealer and told them about the proplem. They told me that my warm idle adjustment needs adjusted but they would have to hook it up to the computer to do it. Then he told me it's 70 dollars a hour. I might just try this video out. I don't want to even get started on this 70 dollars an hour stuff.

$70 / hr. is cheap at a dealership.
Your not in Kansas anymore Toto. :)

I am now noticing some oil leaking somewhere behind the air filter area, I still have the temp tag on. I hope this is not a sign of things to come for buying my first harley

So the dealer fixed your idle issue? How many miles on your bike? Remember, it's a 17 year old bike....it will have a couple of areas that need to be addressed....can't get around that. Start up a new thread regarding the oil and you'll get some fresh responses. And post up some pics!

Good luck!
