Very likely. But why do cheap and easy when complex and expensive is an option?

You must work for BMW

No, but the philosophy here is song the lines of "why buy one when you can get two for 2x the price!"

Since the topic is semi-hijacked anyway...

Last I looked, NEXUS was issued for one specific vehicle that you'd use to cross, which discouraged me from getting it because I may be traveling on either of my bikes or cars. Did that change? (I'll probably should go and look it up myself, I know

).

My solution to that problem is to get off the interstate and use a small rural crossing: rarely a line. Here in New England, on land-based border to QC, there are many of those border posts.

Still, no solution for getting the pig unstuck when in mud, that's for sure....

No need to hack and kluge and experiment.
The signal is all there already!
Read my post #6

That's how it's done on the police bikes.

Email me for the .pdf wiring diagram if anyone is interested.

Or stop at duty free, buy a Toblerone, and get ahead of the line.

Only if you're wearing a bullet proof plate in the back of your jacket.

On 1150 RTPs a relay is sinked to ground thru pin 17 of the motronic ma 2.4.
The relay contacts can be used to automatically and optimally operate the fan.

If you need a contact pin to do this mod, PM me and I'll mail you one.

Interesting. What about the 1200?

Here is a picture of what I've got - SPAL fan - around 120cfm - lighted LED switch is by the speedo. This is bolted to the upper crash bar on a 1200GSA. The SPAL is waterproof etc. (got it on eBay ~$50) but I can only fit one in there. Since I've installed it I really haven't had to use it, so I can't say just how effective it is. I know it works though...

That's correct. BMW do a thermostat engine oil drain plug just for using with their RT fan.

I know of two 1150GS's that have the RT fan fitted after some modifications.

Both have mentioned that they wished they hadn't bothered

Why exactly do you need a fan ? These bikes were designed to run without them. Has there ever been reports of overheating and destroying the engine ? The GS is sold in desert states like Nevada and California and I'm pretty sure if there was a threat of overheating BMW would have put one in as standard.

Ha ha ha just kidding , they can be pretty stupid sometimes. But I'd like to hear feedback of one person who suffered a failure from overheating.

My last trip to the blue angles air show I was stuck for an hour in stop and go here in fl. My temp gauge on my rt was topping out. I tried pushing but that got old. No where to ride the side of the road. Same thing happened at bike week in Daytona. My buddy fried his road king.

towards the bottom.. 50mm (2in) fans come in groups of 10.

ive seen similar chinese "water proof" fans in 60mm (2.36in) and 70m (2.76in)
im gonna get some measurements and look into this..

i know on my r1100gs i have a verticle bar in the middle of my oil cooler so two fans hooked up to a switch would be great for rush hour traffic on those 80-95 degree days.

ebay this mynewfan guy seems on the ball too
http://www.ebay.com/itm/60mm-25mm-Ca...item2a1c9ae28c

hes running his "conformal coating" fans under water for days in the video.
but all these fans are in the 13.2 cfm range.. much lower than your..

work in progress.. lets keep this alive.. find a "cool" solution

It's only long on the Canadian side, getting back into the states.

Why not just use synthetic engine oil that will tolerate the higher temperature without reducing viscosity?

OK Steptoe, now you dunnit....saved a bunch of time and money for folks...

I can see it now....they're all gonna go out and fit some high-$ aftermarket exhaust system to make their boxer louder.
