Race Tuner Problem
« on: April 21, 2006, 02:16:57 AM »
Just had a race tuner installed in my 2005 FLSTFI. Installer cannot get Out of a lean condition under 3000 RPMS. Bike has 300 miles and installer said it has blown head gasket. HD dealer verifies that the Head gaskets are not blown.
If we spray ether on the rear cylinder at about 10:00 along the head gasket at idle the motor idle drops indicating an air leak. This is why the installer said we have a blown head gasket. HD insisting that the head gasket is still fine.
Is there anywhere in the installation of the race tuner that could cause this to happen if installed improperly?
Any suggestions would be appreciated ? I am at a full loss?

You need to do a cylinder laek down test on the bike on BOTH CYLINDERS! This will tell you if you have a problem. You may also have a leaking intake seal. Spray WD 40 around the intake seals. If the idle picks up then that is where your leak is. This could also have an adverse affect on your A/F adjustment or lack of! Spray around one cylinder at a time. Good luck!

Be Safe

Wow...I havent heard about the torch trick in a long time. Candidly I wouldn't have even thought if it. Its been that long. And all very true about using it as a troubleshooting tool.

Here is my .02,
The problem is only under 3000. Personally, I dont think its a gasket problem. When I had my 03-SERK, we diddnt detect that I had a bad injector until playing with AF ratios. Stock it ran fine. It was a lazy injector that only acted up under a certain RPM.

Hd called said I had bad intake gaskets. So they replaced them. I had them already replaced 5 days prior to dropping it off. They still insisted the head gaskets were fine. I asked them to tune the race tuner if they thought it was tunable. They agreed and I made a point that I wanted to see a printout of the AFR straight at 13.7 throughout 1000 to 6200. That is no problem I was told. They even asked me if the reason I was having them tune the bike was to prove the head gaskets were bad. I just said I wanted my bike running at optimum and with air leaks present that was not possible and the AFR should show that. So they agreed and tuned my bike. Upon pickup I asked for the AFR and they handed me a standard Torque/HP graph and no AFR. I was told at this point that they cannot print out the AFR because their sniffer unit was seperate to their Dyno. So I asked what they did and was told they downloaded a HD map and modified it for better performance. I told them thank you but that was not what I asked for and they did not charge me for tuning. Here I sit with the same problem. I called the tuner I first had work on the bike and he said there was no sense tuning it again because it has bad headgaskets.
The HD dealer I purchase the bike from told me to bring the bike to them and they will do a headgasket job. Thats a 350 mile ride. I am not too excited about that. I will try to test it myself and if I get the same results then I will have to go for the ride. I am beginning to lose all trust in HD techs.

Hardley,

See this thread: http://flhrsei.org/cgi-bin/yabb/YaBB.cgi?num=1145937896/0

As Michael noted above, fuel injector is a possibility.

Just to add my two cents, my personal experience with an EFI unit is that if you have a leak at the intake, the bike will rev up as the sensors pick up an increase in air in the air/fuel mixture and try to even it up by dumping in more fuel. I'd be inclinded to go with that blow head gasket diagnosis. Find yourself another dealer.

Brian,

That's the way it would work if you had O2 sensors in the exhaust, like your car or truck.

Well then you just caught my dealer's service dept. in a lie. I had a problem with my 1st 03 SERK about a week after I picked it up running 1500 RPM at idle. When I took it to the dealer, they told me my intake seals were crushed and then explained the situation as I posted here.

No harm, no foul. If we were Harley Technicians with all of our HD PHDs, we wouldn't be here......

This is still a great way to round table our experiences.

Here are 3 graphs to show why I was having so many problems. Please feel free to comment on the results.
The first Performance shop could not tune do to a blown head gasket.??
No pic available. The second said they tuned the bike for optimal performance. This was a HD Dealership. Note 20 minutes spent. Look at the crossover HP/TQ.
The third Tuner tuned the SERT in Advance Mode. 2 hours spent. What do you think?
