Ground spark plug wire well to engine ground. My manual say it can damage ECM if you do not. Battery fully charged. EFI fuse pulled. Hold throttle wide open.

 

So a HD dealer furnished all the parts and did all the work - well - it's definitely their responsibility to make it right then. Good Luck.

As far as the SERT over the PowerVision goes, that's a decision only you can make. I don't know the pros and cons, nor do I have any experience with either so I can't comment.

 

Dont believe the SERT crap. It's completely possible it was a new tech or he/she had a rough day.

Take it back, tell them it is NOT the tune, and demand a diagnostic.

Oh, and the bike will run ok without a tuner, even with a stage 1 and cams. So reflash the ECM and eleminate that variable

 

Why didn't they instruct you that they only preferred tuning with the SERT? Why sell you a PV if the dyno guy rather not tune with one. That was $$ that could have been spent on a dyno rather than resold for 65%

My advice Get a dealer that dosent want to just spend your money. check your comp. all is good Call Jammie at fuel Moto get a new Map. Theres a thread in hear some where that iclick walks through tuning one on his own the thread. find someone that will tune the bike with the Power vision.

 

If the shop didn't re-install the stock O2 sensors that could be your problem. The PV is like the TTS. You burn a map onto the ECM and the O2 sensors are still used to monitor AFR in closed loop just like they did with the stock map. You can still have the wideband auto tune sensors installed but these are going to be up closer to the exhaust port.

If the O2 sensors are installed, just burn the stock map back into the ECM and try it out. The bike will run okay even with the SE255's and Stage 1. You can then eliminate the tuner as a possible cause.

If you don't want to do this take it back to the shop that did the work. They should have provided you with a bike that works properly.

 

The exhaust on the bike does not have the proper size bungs for the stock O2 sensors, so reinstalling them isn't going to happen. I could flash the stock tune back, but I'm not sure how it would react not having the sensors.

I think I'll just do the compression test to see if that is the issue and take it from there. Honestly, the way it's running (not very smooth at all, kinda lopsided if that makes sense) makes me think it's more likely a cam issue somehow instead of the tune!

 

My money is on one of the cams being a tooth out in the chain.
If it's really hard to start and idles and runs very poorly that's the indicator. The compression test is the easiest place to start and you'll know immediately.

 

Proper way to test for compression?

It is simple, just put your thumb in you mouth and blow real hard. Use a mirror or have a friend check your face with a color chart. White is not enough compression, purple is to much, red is perfect.

 

Again, I'm no expert on EFI but I'm pretty sure if you are using the stock map that Fuel Moto supplied and you don't have the O2 sensors connected it is going to run poorly. The PV is not the same as the PCV as far as I know when it comes to blocking out these sensors.
Call FM and let them know you don't have the stock sensors connected. Maybe they can give you a map that is done using open loop instead of the closed loop you are likely running now.

 

Did you go read this Power vision thread by iclick if you have wide band sensors you cant run in closed loop. Call Jammie give him a chance.

Its not the cams. only a idiot couldn't line up the timing marks. someone that knows what their doing just don't make that mistake. You check the dots as your putting the chains on as you put the cams in. you check them again as your putting the gears on and the cam plate is installed .
