So after replacing the starter solenoid the bike turns over but no start. Error code 39, the ECM isnt getting a signal from something. Anyone ran into this? Im out of ideas and ready to take it to my tuner shop.

Thanks

First, did you flash the ECU? Next, if not, then it's pretty complicated describing what to look for. A dealer would be the better option. Seasoned mechanics would be more aware of where joint 2 and joint 3 are located from ECU to joints, to dash in other words. This is not a job for a tuner per say, but if he has the factory shop manual, he can follow the code wires that way.

Unfortunately the dealer has a horrible rep nowdays. As in i wouldnt send my worst enemy to them. My tuner shop is a full service shop with great mechanics. Ive been doing some reading and have a few things to test before i give up. Just need to blow the cobwebs out of my brain seeing as I did 25yrs as a auto tech with exp in electrical. Like the wife said "its good that you use your noodle now and then"

Sorry for the bummer situation.Code 39 sounds familiar...on my 14r.(2013).

In that case,
Disconnect the meter connector, look at the prong side facing you, plastic guide tabs facing up. Bottom row, count from the left- 3rd slot over (LB wire) at the meter connector. At the ECU connectors looking at the left connector, prong side facing you is the LB wire at the ECU. Call this can-hi wire. This will be bottom row, 2nd slot to the right, this will be LB.

Count at the meter connector 4th from the left, bottom row is GY/BL wire. Call this can-lo. At the left ECU connector, bottom row 1st slot, this will be the GY/BL wire.

I may have the hi-lo reversed, it does not matter, what matters is no break at both ends. So it's a simple ohm readout at infinity. It has integrity at both ends or is open at the some point.

Said another way, ECU's left connector, prongs facing you, top row, from left to right, count 27th terminal end is GY/BL. Terminal 28 is LB wire.

So let's look at wire path LB. This goes from ECU out to wire joint 2, then out to meter connector. Thus shows no break from ECU to Joint 2 to meter. Same goes for GY/BL, and that goes to joint 3 from ECU to J-3 out from there to the meter connector.

So technically it can break at a joint or at a terminal end, to a work hardened wire break like Kruz had on his CAN wire.
