Has just over 10,000 miles.Most of everything has been addressed.New plugs,fuel pump and filter in tank has new hoses.Valves are adjusted correctly.....need to look at TPS values.I have the cables and a laptop....
Still wondering if it was running fine before you did all the work.Did you use the special submersible hose for the in tank fuel lines?
The TPS failed on my CalVin (2009) a few years back. It would run fine at full throttle and it would idle ok. I road it home, 1500 miles by alternating between wide open and coast. Not good for fuel economy. I replaced it with one from my local Harley dealer. An early Road King unit. Worked very well and a lot less money than the Guzzi unit.
What is Beatled and what do you gain from disconnecting the O2 sensor?
I am using a PC V W/auto tune with switchable auto tune on my 08 1200S with a 2013 Griso motor. Muffler is free flowing and the air box has the Guzzi tech top, y-pipe is from Guzzi tech. and the basic mapping is Guzzi tech. With the O2 sensor switched off there is no detectable improvement in running but a definite drop in fuel mileage and obviously over fueling. Overall mileage with the auto tune turned on is 39.5 MPG, mileage with the auto tune turned off is 34 MPG. By altering the fuel map I can cause a miss fire and flat spots. I would suggest that you revert the mapping, exhaust and 02 sensor to stock to verify that your problem isn't the fueling and exhaust mods and to pin point where the problem is coming from. MY wild internet guess is that exhaust mods caused a miss match with the fuel mapping and the lack of an 02 sensor exaberates the problem.
Check for intake and exhaust leaks.
Will a screen come up that I can navigate to look at voltages?
If you shut off the auto tune and ignore the O2 sensor and it runs too rich then on the Guzzitech map it would suggest the Guzzitech map is to blame, no?As Dan has said the bike ran fine with the open-loop Beetle map. That's not the problem.Dan and OP, I share the thought that you should check the TPS for overall adjustment and flat spots/voltage drops at part throttle.I wouldn't have expected it to be throttle body balance which really shouldn't need to be touched at such low mileage.
Runs Great now.TPS voltage was off.Seems to run and idle better with .750 volt at idle instead of .450.Also balanced the throttle bodies with vacuum gauges.Thanks to all that replied....
I'm glad the ole gal is feeling better, Dan.
Me too Was cleaning out my closet and found some parts for the CALVIN. I owned the bike prior to Dan (forgot that I had them) a couple of chrome side covers, "bag lady" luggage liners, and I even have a NOS Guzzi tank bag that I never took out of the box
