Ok went to Harley shop again the LEDs or the radar detector oor the MTX speaker system was what caused the earlier problem of reading ECM. The ECM is programmed for the screaming eagle heads and Rinehart racing exhaust, So now I have decided to put the SE heads back on. My question is this. Does anyone have some SE heads already set up they will trade or something for the ones I have? Mine are powder-coated red and have the fins jeweled already and not a whole lot of miles on them.

On the front head the intake valve was broke off when piston hit it but caused no other damage

And I still believe the exhaust needs some backpressure. :)

How did you load the map via powervision in the first place? Do you have a different PV now? Any PV unit , married or not can make a log file. I suggest hooking it up. Run a log and send the file to us. Lots of data there to view afr's and sensors. You only need a license to unlock a PV so it's capable of loading a calibration.

I don't have a pv. I had harley hook theirs up and tell me what they found.

The dealer that SAID they programmed my ecm is some one loaded the ecm when I put the SE haeads and rinhart racing exhaust on bike. I suspected they charged me for modifying the ecm for SC but didn't actually do anything. But couldn't ever prove it. Turns out that is the case. I went there and confronted them about it. Didnt go well. Without going into details I almost went to jail when the cops came. Im banned from going back there when they are the ones who ripped me off.

Don't know what to tell you other then the dealer isn't capable of supplying a base tune for SC you had before. There are no flashed tunes beyond 1 bar pressure. Even if one was smart enough to scale a HD cal, it can only be dialed in on a dyno from that point. Not an easy cheap task.

So after blowing the engine after a misguided alcohol influenced failed attempt at a supercharger install (piston hit intake valve broke valve off in cylinder and punched in the piston and blew out the cylinder wall) I purchased a used engine off ebay.

The original engine had screaming eagle heads, Rinehart racing 2 into 2 wide open exhausts so straight pipe basically. Open top with airbox cut down to size of air filter.

Only difference between the two engines other than the heads is the input air sensor is mounted on the front head down in the valley between two cylinders instead of on airbox. A 2002 engine. I left sensor plugged in and continued using the one I glued in airbox lid.

Thanks to TaxManHog finally got it running after splitting the cases couple times. There is a thread on that here somewhere.

Now here is my issue(s).

It obviously needs a new fuel map bigtime. Max speed with throttle almost wide open is about 77 to 80 mps.. Im getting less than 30 mpg. Have to rev it pretty high to have enough power in first to get rolling and it is way louder than it ever was. ANnoys me even much less people I ride by. And coming off throttle will die everytime. It will idle if I'm not coming off higher rpms. Coming up to stop lights if I don't nurse it it will die.

Took it to harley to download a new fuel map. I had the map I needed. They hooked the power vision to it and it starts to read ecm then says no ecm found. Guy tried for 2 and a half hours to get it to connect to ecm. He told me I had a bad ecm and I said then how did I just ride it here? Then bike wouldn't start for half an hour ..Something with security system got jacked up. Told him let it sit for half an hour after removing maxi fuse and then it started right up.

He didn't want to touch it after that. Im a disabled veteran and to the guys credit so is he so he didn't charge me anything for 3 hours of his time. WOuldnt even take a 20 dollar bill.

Said all that to say this.

I cant afford a pc3 or PC 5 or powervision license right now. I have 6 weeks to finish auto deisel tech school and need to have bike running to get to school and back.

SO,,,, I know I need to restrict airflow thru this engine. Thats major problem.

So without spending much money or any money any suggestions on restricting airflow in the intake a bit? And restricting exhaust using washers maybe? If I had slip ons I would install that homemade baffle using I thumbscrew I read about. Also when ideling I can feel at back of exhaust lot more exhaust pressure than it used to have..

Any thoughts?


I trimmed airbox to what you see here and pic of the exhaust

Maybe too simple but I had similar issues with my 03. It was a loose tube downstream of the fuel pump, before injectors.

Do I understand correctly that you're changing out the stock heads and cam from your eBay engine?
Installing the ruby red SE heads and the cams it had?
I'd assume the shims you had in the red heads should be good for the same cams it ran on originally.

OR

Are mixing the cams from the eBay engine into the red SE heads?

Read your manual, the process is detailed, measure the clearances, if adjusting is needed, acquire the shims from HD if they still have any, or check eBay for a complete tuners kit.

I don’t know the exact part/assembly. The local Harley shop did the work. It took them a while to diagnose but it fixed the problem 100%. It was internal to the fuel tank; no external fuel leak. I haven’t looked but the service manual may have a procedure to check pressure at the injectors. Low pressure would indicate a leak or a fuel pump problem.

That motor is not tune for the wide open exhaust you need to have the motor tune to match the wide open exhaust mine did the same thing After I took out the baffles

Those separate straight pipes are probably the worst pipe setup for the Revo engine, bar none and prone to excessive reversion. I read somewhere here the engine runs best with about 3 Psi backpressure - and thru a 2-1 exhaust system for cylinder scavenging. Long stroke low Rpm H-D airhead torque engines tolerate those pipes but they are not efficient on a 9000 Rpm hp monster. Inappropriate for the job, form over function. Install some thumbscrews in your pipes and after you get the fuel adjusted properly with the current heads and it's running well and you get some $ ahead again think about ditching those pipes and buying something good like a Bassani Road Rage or B1 you'll be amazed at how much better it pulls after you readjust the fuel for the new pipe. Good Luck with the fix sounds like you're getting there finally ! And glad you pissed off the guys at the dealer - they probably at least helped you blow up your SC engine - another reason not to use the H-D dealer they just don't get V Rods or especially boosted V Rods. :cool:

Engine sounds great. At idle. starts right up everytime.

I restricted the airflow like I said and it helped alot.

I read about how LED lights and accessories can mess with voltages on ecm and I had 5 different led light kits on her when I took her into harley . Also had mtx speaker system , and radar detector, I have since taken all that stuff off. She was lit up like a xmas tree. People would certainly see me and not run me over

I read how one rider took the screen that was used to keep leaves out of gutters and he rolled a piece of it up in a cone shape and shoved it in the exhaust for some backflow and how well it worked. Im going to try something like that.

Thanks for the info. I tried putting some different size washers in the pipes with varied results. Notice how I have the LEDs on the rims? I mounted round LED devices on inside of my brake calipers front and back. ANd then I put LED strips in rear fender that reflect off the solid chrome shocks from the rear giving me extra brake lights. I have four different LED kits on the bike and when I use left turn signal all the lights on left side of the bike blink same with right side for right turn signal. Plus I have the Killer glass setup and a skull horn cover has red led for eyes. I included pics of my first vrod I got in 2002. First one in dallas to have the 100th anniversary bike. Then a pic of my second vrod I bagged.

I have a lawsuit ready to file tomorrow on Maverick Harley Davidson for straight ripping me off and alleging that them lying about putting proper tune on the bike for a SC led to engine failure. The fact they charged me $299 for the tune and didn't do a damn thing. Plus punitive damages. My mother is/was a lawyer. Civil litigator. SHe lost less than 5 cases in 40 years and she taught me a lot before she passed and I have NEVER lost a lawsuit yet. This is not a one-off them ripping me off. I took my bike for nothing but an oil change 4 years ago and they call and said they found metal in my oil and my bike needed an engine overhaul and if I would authorize $2500 on my card they would get started on it right away. It was all a scam. I asked them to show me the supposed metal they said they found in the engine and they hand me this round thing that I have asked all over the internet if it was possible to come from somewhere in my engine. Not one person on any forum anywhere could tell me what it was. But they did tell me it didn't come out of my engine though. They brought my bike back to me in a trailer saying it wouldn't start. All of a sudden it had two bad coils. Another time I took my rims in to have new metzler tires installed. They installed both the front and bike tires backwards rolling the wrong way. When I called and bitched about it they said bring my rims back they would fix it. They took 6 days to fix it. I have not found one reputable Harley dealer/service center yet. I called all the Harley dealers in dallas fortworth to get a price to download my tune which I already had to my ecm. I gt prices from $65 for half hour labor to $399 for all kinds of shit. They spouted off a bunch of psychobabble for the higher prices and I just acted ignorant as I recorded all the calls. . Thats rediculous.

Well, I'm not sure why I am responding but here goes. First... Have you sorted out the map that is currently on your bike? Without that fixed you will NEVER have it running right. Forget your fancy lights (for now)and get to the route issue. As far as the lawsuit goes, well, this kind of stuff just pisses me off. I see more and more of this entitled attitude. yes I'm sure you had bad experiences with the dealer.. Who hasn't ? But........ you admittedly said in the very FIRST LINE of this thread that alcohol was the cause of the SC failure. How is that the dealers fault? Sorry for coming across rude, I just like the straight goods. As I have said for many, many years... there are 2 sides to every story..... then there is the truth! I do hope you get your bike fixed and running well though..

That bike. even with those pipes should bounce off the limiter all day. Just won't have the low end torque a good 2-1 will have. Three things need to be done. Do a fuel pressure test. Datalog the bike for an overview of all sensors. Be it TTS or Powervision, which many of us can view the logs and determine what's up. If all good then deal with the calibration, which the above two can do both data log and load calibrations . You are just pissing in the wind with back pressure as a fix. Boils down to a systematic approach and throwing a bit more money into it. As for the law suit, good luck. I , we, tried to sue over a patent deal but we didn't have a dump truck full of money, plus HD has a room full of vultures ready to do legal battle. Still pisses me off after 8 years but it is what it is.

Yea Ron backpressure as a fix ain't going to do it that's for sure - but a 30 - 45 degree thumbscrew in each pipe will make tuning easier with a touch of backpressure, much less reversion and give better low end torque. I wouldn't install new heads either until the current engine is running properly - also gmanvrod how the hell is the head still good after it dropped a valve and cracked the cylinder liner ? Gotta be damaged, from a very violent crashing together of parts - if not damaged then why don't you just put a new valve & guide in it ? Hope you get it running right soon ( before the wife kills you - :confused: at least that's what would have already happened over here at my house )
