Cooling Fan Question
I was doing some maintenance on the bike today and pulled the radiator only to find the fan is a direct drive from the engine and not electric like most other liquid cooled bikes. Is this normal for the Silverwing? Also had to replace the wire to the temp sensor while I was there. I seem to be having a issue with running bad after it gets heated up. I will also have to do something with the radiator because it developed quite a leak. Anybody have one they want to part with? Another challenge to get this one going.

While you're in there make sure the fan is nice & solid. I have read about several that have come apart.
The main plastic part of the fan separates from the aluminum hub and if it isn't caught it can come off and destroy the rad.
It is my opinion that the separation is caused by overtightening the bolt that holds the fan onto the shaft. The shaft has a tapered end and the aluminum hub has a matching taper. When the bolt is overtightened the hub is forced onto the shaft too far and spreads, cracking the plastic and sometimes breaking the bond between the hub the fan.
This can be prevented by using a torque wrench.
BTW: If you ever need to remove the fan, the proper tool for pulling it is simply an M14x1.5 bolt that is threaded into the inside of the hub so that it pushes against the end of the shaft.
Don't try to use a front axle as a puller. It has the right thread, but because of the tapered end it won't engage the threads inside the fan hub far enough. It can pull the threads out of the hub before the hub breaks lose from the shaft.

Thanks Sidecar Bob,
The fan seems like it is solid, I even ran the engine with the radiator removed in order to observe the fan flex. My mistake was the spacers on the two bottom bolts were put on in the wrong sequence causing interference and damage to the radiator. Damage was very quick and not easily repaired. Yes I learned a lesson that day.
