WTF is this shit?:

On the engines missing when it gets hot is basically covered here.
S&S module also has engine
overheat protection built into the software. If the
cylinder head temperature reaches a predetermined set
point, the module begins skipping sparks. This
noticeable misfire not only alerts the rider that the
engine is overheating, but also cools the cylinder heads
with unburned fuel. If the temperature continues to
increase, the missed sparks become more frequent. This
alerts the rider that the overheating is becoming more
severe, and provides more cooling to the cylinder heads.
The third stage of overheat protection is very noticeable,
and will cause the engine to run badly at idle. The
overheat protection function can not be disabled, and is
one of the factors that allows S&S to offer increased
engine warranty on complete engines sold with the VFI
system.
The head temperture sensor is one of the mounting bolts in your intake on the front jug I think. I posted the temps it starts acting up but can look them up for you if needed. They are in the manual.
Yes it can strand you.
Only in the EFI bikes....

sorry if i sound dumb, i am clearly not a mechanic or an english teacher. but why is the temp to start protecting the bike set so low. i would imagine that my temp would be the same as the other bikes that i am with?

You are electronic controlled so they can tune your bike very very lean to meet EPA restrictions. It also helps longevity of the bike as far as they are concerned and less potential for motor damage.....
Less power, less breakage or wear and tear on all the of the mechanical parts.
I thought it sucks that they made it a mounting bolt of the intake on the jug instead of a stand alone sensor.....

I am going to be nice and not say what I really think about the FI systems that come on these bikes.

Anyway,
Thermal cut #1 350 degrees.
Th engine will miss one out of every nine revs. You can ride it as you have experienced but the engine is over heating as far as the software is concerned.

Thermal Cut #2 365 degrees
The engine will miss one out of every seven revs. It is getting pretty rough to ride now.

Thermal cut #3
The engine will miss one out of every five revs. Forget riding the bike and ask your buds to bring you cold beer. The whole point to stop the firing is to allow raw fuel to help cool the motor but you are getting pissed and need something cool too.
Once the temp is below 325 it begins to ride again as it did before it made you pull over and wonder what is wrong with you sh?t, providing as the manual says, it nothing is damaged
No , carb bikes don't do this, they make it to the bar.......

i think my next purchase is somekind of temp sensor. i really believe it is doing this too soon. any recom.. on a digital sensor?

I have a 2007 EFI Bulldog, it will overheat very quickly in traffic in excess on 90 -95 degree's. It takes around 12-15 minutes. It will correct itself once moving again. But, it is bull. Other than this issue, my dealer wouldn't install 600 cam mod because of the EFI. Starts great and runs excellent 98% of the time.

Well like Jesse James said on one of his TV shows, Carb all the way, EFI ? Well that's how the cops are gonna catch ya. Hit a button and your shut down. Interesting, surprised the technology ain't out there yet, or is it?

I would think you could simply put a resistor into the circuit and make it think it is cooler than the sensor says it is so the software does not go into misfire mode...

My 07 Bulldog runs great near mid to end of each season in Michigan. But when I pull the battery for storage the EFI needs to relearn the mapping again in spring and spits and coughs once in awhile for a few 2k miles till it relearns the routine. No big problem! I just go on with my ride and enjoy life on my Bigdog!!!!!!!!!!

BigDogBro1,
After 20 miles or so it should know everything it needs in the mapping and run fine then.....The base map should stay intact and it is only making changes for the daily factors of the weather and bike sensor conditions....Perhaps BDM needs to re-flash your map and firmware to there latest version...

I have 2007 Bulldog .. Feb production. I have issued when the temperatures gets above 90 a mild traffic.. Lucky, it has not cutoff. I do like the easy start and general performance. I do agree, at 4,000 the torque seems to flatten out.
