What did you do with your ST1100/ST1300 today?

Checked the wiring on the ST for the code 26 FI problem, wiring good to the ECM. Put the plastic back on and ran the engine up to 4K for 10 seconds, the light came on and the engine RPM dropped nearly 2000 RPM. Looks like I have to go back in again.... Since there is no connector to guide the wire onto the pin of the knock sensor, I may not have gotten it connected. It's never done that before when the FI light came on.
Also got my Spencerized Riders Seat back today. Hopefully, I will get a chance to ride it soon..... Back to the Salt Mines!
 
I suppose I could rewire the ceiling fan and replace the five light bulbs with H4's.
Then when I turn on the lights it would sound like a swarm of bees overhead....
I don't think the lady of the house would like that.....
 
Just got home from a 226 mile ride on the Honda ST today ahead of the rain. Temperature was 62 for the high and 52 for the low.

Fabbed up a couple small tube supports for my dash. Kinda thought it was getting heavy. Then went for a 100 mile test drive up over Cheaha mtn. Got to make sure it's good in the twisties. The glare on my tablet is terrible mounted in the middle. Gonna move it back to the left side.....then bought tickets for Southern Nationals and COTA moto gp.

Went for a short trek of 60 miles this afternoon in the 64*F sunshine to test out the reworked turn signal switch. Better than new. Gotta restore the right side next. The kill switch is a little flakey.

Went to my kids highschool parking lot after hours and practiced u-turning. Getting better at it, but not as good as the pros yet.

Also testing new Sena Prism Tube WiFi helmet cam.

I can tell you that your ST clutch is pretty much bullet proof so you can practice your slow speed maneuvers in the friction zone a lot but just ride a couple of minutes in between U-turns with out the clutch to cool the plates.
 
waiting for a little warmer weather to fill with fluids and check for leaks after my major winter over-haul including installing new alternator and vacuum lines.

Could it possibly be one of the vacuum lines into the 4 way T? I have heard of that T getting clogged and causing erratic idle.

I will check, but this FI code 26 problem was coming on the bike when I bought it, that's why I got it so cheap. I have just got around to investigating it. I suspect since the wire to the right knock sensor had been spliced, I think I didn't get the connection back on correctly when I pulled it off the knock sensor to check the wiring to the ECM. See pic (attached). And the ECM thinks the knock sensor is bad. I suspect that is what caused the large RPm drop. So I am going to pull things apart today and check the connection and try to do a proper repair rather than use what the "mechanic" had done to keep from replacing the engine sub harness. Always before when the light came on there was no loss of RPM, just the light came on and the bike did not go into limp home mode. IMG_2891.JPG

Thanks, but that is exactly what is happening. I pulled the middle and lower cowl off today; I am getting good at it; and checked to make sure I had the right know sensor (black wire) connected properly and it was connected. Did the rpm test again twice and the same thing happened.. When the FI light came on, the R's dropped more than 2000 RPM. Never did that when I had the FI light come on while riding, couldn't really tell any difference in performance or fuel economy while riding with the light on.... I have checked all the knock sensor wiring all the way to the ECM on the right side and it has continunity. I am going to pull the middle cowl on the left side and check that wiring tomorrow.. I have an ECM (used) on the way from a 2003 that should be here on Monday. I will install it and see if I have the same problem.
I am curious... The corrections to the service manual state that the code 25 and 26 are reversed.. Meaning that the code 26 is the left knock sensor rather than the right that the service manual states. Is that correct or not?

I don't know I am going to look that one up.
I would start with that harness and consider 2 new knock sensors. It is possible you have a broken wire with in the harness and or a bad knock sensor. I just replaced my RS sub harness because the coupler to the knock sensor got brittle and broke. That harness has to deal with a lot of heat off the engine over time.

I have a new engine sub harness and one new knock sensor, but I am reluctant to try and replace the sub harness as you have to nearly pull the engine to do it. After I check out the left side wiring to the ECM, I may wind up having to do it... The right side knock sensor passes the tests in the manual...
 
I installed a usb port dongle with a voltage gauge on it in the left fairing pocket.

I also sat and pretended since theres still a crap-ton of snow here. :p
