When the bike is in closed loop, the map is safely on the rich side and the signal from the O2 leans it out for fuel mileage and emissions. It's done this way so if the O2 sensor, or sensor circuit, where to fail there is no melt down. By eliminating the O2 sensors you made the O2 signal voltage zero which makes the ECU think the bike is lean, making the bike run on the safe rich side. However because you had the Turbo City FPR, it was the 'extra' rich side. If you would have left the O2 sensor, closed loop would have dialed the extra fuel out at cruise and your fuel mileage would have been unchanged at cruise. You would have still had a very small decrease in fuel mileage outside of closed loop, but that would have been fairly slight. In theory, there is no throttle response at cruise so having closed loop leaning things back out should not be an issue, thou it might make for a surge coming off cruise.

I can't find the FPR on TC can you post a link, I have a 01 vfr800,Thank you Turbo City stopped selling the FPR units. At present, I don't find anyone that makes/modifies an FPR for the VFR. You can always order one for a Blackbird.

Actually, the stators don't generate amps, just voltage. The amperage is dependant on the load the stator 'sees'. If you're not shunting (loading) the stator to regulate voltage, the amps drawn should only be what's needed by the bikes electrical system, minus rectifier and 'normal' regulation losses.

I'm just going on "wisdom from the Internet" (which, it must be remembered, used to recommend the CompuFire...), but there have been some reported failures of the SH775 at high rpms. Shindengen's website has this graph showing their series-type reg/recs: I haven't ordered a box-full of Vstrom reg/recs yet, but I think it is possible that this is one the 50A series reg/recs shown as "under development" in the table above, and if so, could be the "OEM-type" solution we have been waiting for. More guinea pigs required! Ciao, Of coarse, V-strom is a twin so.....

I've been running one for about 4k miles now, no problems. I've installed a meter to monitor. Shortly after to install, I ran it up to 12k a couple times (close to home), voltage never over 14.8.

whatcha got there?Is that a stock filter frame with a BMC filter element? Inverted? Sent from my SCH-I200 using Tapatalk http://www.vfrdiscussion.com/forum/index.php/topic/65961-frankenfilterit-breathes/

For those interested in doing there own installs, I will continue to make the relays that prevent the ballasts from being energized until the bike starts. The relays also now include a "override" in case you want lights before the bike is running. You can also use the "override" to hold the ballast energized when the high beams are on. PM me for details.

My Compu-Fire died under high rpm. http://www.vfrdiscussion.com/forum/index.php/topic/74088-my-compu-fire-regulator-died-today/ I replaced it with a Cycle Electrics 50 amp series R/R (I'm not giving up). First trip out I ran the RPM up (close to home), no problems. Couple thousand miles now, so far, so good. http://www.vfrdiscussion.com/forum/index.php/topic/74126-ok-second-try-for-a-non-shunt-type-rr/

My Compufire died (I suspect over voltage on the input side). I'm using a Cycle Electrics, it's 50 amps and a true series style. I verified it's a series style by measuring the current from the stator to the R/R. I was going to use the 'load to heat' method, but I just happened to have a meter handy. Details here - http://www.vfrdiscussion.com/forum/index.php/topic/74126-ok-second-try-for-a-non-shunt-type-rr/ Harbor Fright sales a little load bank perfect for that. Dont remember the model # but it seems like it was $60-$70 ... I just used an amp meter. Why would you need a load bank?

The same way Dennis Rodman performs like Michael Jordon! Yeh except BETTER !!!!!!!! And I think Dennis Rodman understand OHM'S LAW !!!!!! That's properly not the only law Dennis doesn't understand.
