Checking Coolant Level - Simple Mod

Mokkybear 06-20-10 07:27 AM

Many have bemoaned how hard it is to see the coolant level through the small slit in the fairing - especially ST owners, who can't get torchlight onto the coolant tank because of the shroud each side of the radiator. A simple fix is to add a small LED array behind the coolant tank. I sourced one from my local electronics shop for a few dollars - four white LEDs with a resistor to suit 12V power supply, encased in clear acrylic to make it robust and waterproof. I attached the LEDs with...

Meanwhile as a simple fix for this, move the original clamp to just after the spout, push the hose back in until it touches the locating lugs. Place a a screw-on...

Coolant leaking?

kismetcapitan 07-16-08 03:04 AM

Ever find white streaks on the right side of your bike, or worse, blue coolant dripping on you as you ride? If your coolant is overfilled, and you're running in hot weather (or driving like a maniac in any weather!), what is happening is that the overflow valve in the cooling system is opening and releasing coolant. From gathering F800 riders' experiences, it appears that the problem is simply one of the reservoir tank being overfilled. 1) remove the right upper fairing. Take off the...
