Chuck Posted February 25, 2017 Share Posted February 25, 2017 Did you crank it? Link to comment Share on other sites More sharing options...
czakky Posted February 25, 2017 Author Share Posted February 25, 2017 No, can I crank with the plugs disconnected? Link to comment Share on other sites More sharing options...
MartyNZ Posted February 25, 2017 Share Posted February 25, 2017 I'd pull the plugs from the ECU to the coils at the coils out. Then you won't have so much risk. Link to comment Share on other sites More sharing options...
czakky Posted February 25, 2017 Author Share Posted February 25, 2017 Won't that kill power to the fuel pump though? Link to comment Share on other sites More sharing options...
MartyNZ Posted February 26, 2017 Share Posted February 26, 2017 My $ is still on a timing problem. Have you done anything to affect the valve timing, like a new timing chain & tensioner? I managed to mistime one camshaft on a DOHC engine, and it ran sluggishly one tooth retarded. Mistiming a Guzzi camshaft would be much worse, as it affects both intake & exhaust valves timing, and ignition timing via the phonic wheel. Another thought, GuzziDiag will report the Crank Position Sensor as failed if the gap is slightly too large. Setting the gap correctly with a thinner shim made GuzziDiag happy again.

czakky Posted February 26, 2017 Author Share Posted February 26, 2017 I did replace the o-ring on the sensor. I had logged into guzzidiag the other day and didn't see any faults. Although it wasn't running. Link to comment Share on other sites More sharing options...
Chuck Posted February 26, 2017 Share Posted February 26, 2017 No, can I crank with the plugs disconnected? To the best of my knowledge, as long as the plugs are grounded you can. Don't trust my aging memory, though..ask somebody that knows. Link to comment Share on other sites More sharing options...
gstallons Posted February 26, 2017 Share Posted February 26, 2017 You can , I would ground them or use a clip-on spark tester on both wires to keep stray spark from giving you unwanted results . Link to comment Share on other sites More sharing options...
czakky Posted February 26, 2017 Author Share Posted February 26, 2017 Im sorry for my confusion. You're saying if I pull the plug wires and install a plug then ground the plug it's ok to crank? Link to comment Share on other sites More sharing options...
Chuck Posted February 26, 2017 Share Posted February 26, 2017 Yeah. Link to comment Share on other sites More sharing options...
czakky Posted February 26, 2017 Author Share Posted February 26, 2017 I watched a big beautiful spray of fuel come out of the injectors no visible dribble/leak. I've gotta say that the spark although it was there wasn't as consistent as I would've imagined. It was blue and sometimes orange-ish. My battery was dying too. Guess it's on to timing/ECU. Does anybody know if a 15rc is a direct swap with a 15m? I will need to load a map onto the new unit so it's got to be guzzidiag compatible.

czakky Posted February 26, 2017 Author Share Posted February 26, 2017 It was running great. I parked her probably November. Pulled the battery had it in my basement most of the winter. I'm not 100% sure it was never exposed to below zero weather this year but I'm pretty sure it hasn't. I will say this though, I bought an odyssey approved automatic charger. It doesn't seem to charge above 12.65. This would be a "before things went to hell" thing too. My old cheap auto charger would get her to 12.85 atleast. Also I WAS charging on pigtails in the bike.... not since my issues but I did a couple times. Link to comment Share on other sites More sharing options...
andy york Posted February 26, 2017 Share Posted February 26, 2017 Everything seems to have been covered .....but..... has it back fired? Make sure both intake rubbers are mounted securely on the throttle bodies and that they in turn are fully seated on the intake manifold. andy Link to comment Share on other sites More sharing options...
czakky Posted February 26, 2017 Author Share Posted February 26, 2017 Yes she's back fired many times. Visually the boot from head to TBs are good. I've attached and re-attached the air box a couple dozen times. Making sure to check. I've done the carb cleaner spray while she's running just to be sure she's not leaking. Good points though.

czakky Posted February 26, 2017 Author Share Posted February 26, 2017 Could it be my timing chain jumped a tooth? I've never replaced the tensioner. Link to comment Share on other sites More sharing options...
