BOOSTER PLUG GRISO & Calif 1400

[GUZZI HEAD]

[/color][/size][/font]
Read several negative comment on the Booster Plugs????  Booster Plug solved stalling problem with 1400 California when coming to a stop or idle.  On the 8V Griso helped starting, idling and relieved popping in exhaust on down shift.  Also have this device on my BMW R1100 oil head.  If location has anything to do with this success I'm in Wisconsin.  I have had several Power Commanders and even a Juice Box no need for added performance simply smooth engine mannerisms with my twins

Adding 6% more fuel across the range seems unnecessary to correct lean fueling in only certain throttle openings. I would think it better to just load a proper map, corrected for any exhaust mods ect.
 I'm glad It seems to work for you, but I've seen first hand what over fueling can do in terms of accelerated wear  to engine, so I'll pass.

Sensor coolers are the work of the devil and should be ruthlessly stamped out! They are a truly nasty kludge.

What exactly do you mean by a “booster plug”? Is it something that essentially makes the bike run in the cold start mode all the time? If so, on some bikes you only need to disconnect the O2 sensors to accomplish the same thing. I’m a huge fan of a PC5 or a Maximus tune as I’ve seen firsthand dozens of times on how well they can make a bike run. Nearly every road bike in the US was tuned to the EPA and DOT regulations which are never for the benefit of maximizing the engines performance potential.
My O2 sensors have been relocated over 55K miles ago and the PCV has performed wonderfully.

I would have spent that money on a map from Beetle!

+2.   Running Beetle maps on 3 Guzzis, Norge, Griso, V7.  Amazing improvements on all.
