Thermostat in the Valk begins to open at 169-176F. It should be fully open at 194F. I couldn't fing anything on fan start.

Thermostat in the Valk begins to open at 169-176F. It should be fully open at 194F. I couldn't fing anything on fan start.I have the Valk genuine workshop manual. It omits interesting things like the main bearing journal and big-end diameters, although it does include many other dimensions you don't need to know to maintain the bike. For example, the valve timing. This engine has no valve overlap!
One thing I miss on the Valk is a temperature indicator. My Daytona 955i has a digital one, so I know that the fan starts at 103 degrees C (set in the ECU).
Does anyone know what coolant temperature the fans in the Valk start at, and the temperature when the temp warning indicator lights?

The valve timing spec numbers in the service manual are taken only at a set position of 1mm valve lift. Valve overlap does take place on this engine but to a lesser extent than some other engines do. In other words the overlap takes place when the valves are open less than 1mm. The attached graph Is Not from a GL1800C but is the closest I could find with a short search. It helps to show the valve overlap compared to lift. On this graph the overlap triangle peaks at about 1.5mm but an 1800 F6C's of course would peak at just under 1mm. This graph is not marked for what model its for but I highly suspect its for a GL1500C 49 state model. The GL1500C California model had different cams with less overlap similar to the GL18.
**** you people! Another widget added to my wish list. I think I'm spending more on this bike than I've saved in car insurance. Well, at least I'm not spending $300/month on gas...yet.I have the very same indicator (Red). Red and Blue are very visible during the day. Basically plug and play, go through the gears and you are good to go! I've had the indicator for two years without any problems! I mounted it on the left side of the speedo gauge with the provided double sided tape.![]()
