I was viewing some posts that started with voigtstr that went cold last month. I thought it was worth reposting to keep awareness up.
If your Guzzis running hot its not happy . Read," it could eat itself up!" Of course these bikes are set up lean to get through Ellis Island. Pinging is dangrous detonation that erodes the piston tops .
New , my sport pinged on some fuels, some conditions. I synched the throttle bodies, removed the carbon cans ( off road use only) , and 'tweaked ' the throttle position sensor. Voila! No lean behavior at all!
My dealer copped some set up from some 'tuner.' It was so rich my plugs sooted. I think he was trying to fuel cool my mtor to prevent an engine claim. It would routinely 'pop' upon hot restart (like ata gas stop) and blow the right throttle body off! Very embarassing and annoying.
Finally, I reset the TPS at a more conservative setting. No pops, no hot or lean condition signs (no piston erosion ?) . The procedure requires a digital volt meter, "back probing" the computer ( putting a couple straight pins in right connectors ) and setting the TPS. The ECU basically sets the curve a little richer as if the motor was at alittle higher rpm. Very easy very cheap , very effective,
Why don't 'dealers' (I want to call them pushers- same thing-right?) do this? My dealers' set-up philosophy ( Mixture, sychronization) seemed to be , "hey, it starts ,it runs-don't mess with it!"
We can do better than that guys! These bikes run GREAT when they're set up right. Don't let a lean condition eat your motor!
Let the big dog eat! docc
