I just might have a rs scoop 4 sale.
I might just remove my fan altogether. Will this wreak havoc on anything if it's not there, electrically?
You'll just get a CEL and a code, unless you uncheck the 'fan' on the Error Mask page of ECM parameters in ECMDroid.
But I gotta ask. Why?

The only time it comes on is when I'm coming off the track, and it's on for less than a minute. I'll take a look at the error mask and see if that's how it coded, on for 1 minute.
My reasoning for removing it is I check header flange bolts quite a bit as these seem to need retorque all the time and taking the fan off would expedite this. Remember this bike never sees the street.
Bad idea? Last time I used a locknut the stud broke. Torque for these studs is 15 nm.
[QUOTE=outthere;624901]But when you shut down and the motor is doing a hot soak, the fan will help keep airflow moving across the cylinders/head and prevent oil coking and premature breakdown at very least.
On my XB's the fan only came on when it was running really hot (aka summer in AZ) or during shutdown.
Are you positive its not coming on while blasting around a race track? Can you even hear it? It's your bike, but IMO a bad idea.
Alternatively:
Use these https://www.stage8.com/product/re-se...eader-nut-kit/
You might have to change the studs to use those, or the same company makes bolts too, and that makes header R&R massively easier.
Or, safety wire them, or use a stover lock-nut. I wouldn't blame the lock nut for breaking a stud if torque spec is only 15Nm. Sounds like the stud was compromised to begin with.
Either way, the constant loosening and re-torquing will fatigue the nuts, studs, and the thread in the cylinder head as well. You're asking for trouble.
