In the Accessories & Mods forum, I was tossing around the idea of relocating an aftermarket radiator overflow bottle to the right side of the bike directly behind the radiator.
I would like to keep the airbox, so relocating it beneath the tank is moot.
To fit the aftermarket bottle, I will have to either move the right fan inward or remove it.
Any problems running with one fan? Mine only come on at 215°F -- a temp not often reached.
Well the old sbks are fully faired and only came with the left fan and they were fine. You could try and see how the temps do.
My 996 has no fans and never climbs over 195-200 if the bike is moving.
I've never seen higher than 250 with the bike idling on the hot pit in 90 deg ambient temps.
Thanks guys.
I'm just gonna remove the fan and keep an eye on the temp.
It'll be nice to remove the OEM overflow bottle. 8)
I've found that my S4 runs about 100 degrees over whatever the ambient air temp is, so it takes a *hot* day and getting stuck in traffic to kick the fans on.
They're not particularly effective fans, temp seems to marginally hold or go down *slightly* when they come on.
The bike really needs to be rolling to get any temp reduction.
That's not to say that the S4R is the same, the 996 engines seem to run hotter from what I've seen.
The SBK single fan is a good bit bigger than the ones fitted to the Monsters.

Hmmm...there are quite a few superbike fans available on eBay. Maybe I could switch out the elecrical connection and fit a larger fan to the left side of my radiator. I'd have to fab some mounting brackets too.
I have a radiator from a SBK with one fan on it. I will go measure it and compare to the fans on the s4r. If it is indeed bigger just send me shipping and I will mail it to you. I have no use for it now.
Riding around in traffic, here in Atlanta GA during last summer...when it was 100 deg out....the fans on my bike kicked on one time. I had been stopped for over 10 mins. [thumbsup]
I've already pulled one off, and had no issues. I run evans NPG-R coolant in mine, and also considered capping the overflow as this particular coolant doesn't expand nor run underpressure at temps under 400. Still have a bottle on there....for now.
I've been running my S4R with no fans on it for about 2 years now and never had my bike overheat, both at the track and on the road. The only time it ever comes close to the temp where the fans would kick in is if I let it idle for an extended period of time. I mounted a small bottle on the right side of my rad for an overflow bottle and it's worked great. I used an oil sample bottle i got from work.
Thanks Theo and Johnny!
Do either of you know if the OEM overflow container will sneak through the right side of the frame, or must I remove the airbox and throttle bodies to lift out the overflow bottle?
Edit: Nevermind! You must raise the throttle bodies to remove the overflow bottle. It only took 30 minutes. :)
It already looks much better!!!
Now if the aftermarket overflow bottle would arrive today.
