Although a bit too modern looking that subframe is beautiful.

A mo.unit wiring video would be amazing! Haven't found any good videos for the the newer K1100RS. I'm building a 1995 with some of your parts and am stuck at the wiring process.

Enhorabuena por el vídeo. Tengo una k1100 y vivo en España. El radiador y el ventilador que usas puede ser bueno para evitar que mi moto se caliente? Dónde los puedo comprar. Gracias!!

What clutch release lever actuator are you using?

[@tillgal]

nice video! it looks like you just let the cooling water flow to the ground instead of using the tank, am I right?

[@Powerbrickperformance]

Yes, correct, the aluminum radiator combined with the SPAL fan and the silicon hoses in combination with the removal of most fairings make the overflow tank abundant in normal climates where temperatures do not exceed 35 degrees celsius. Also as the radiator is build to race spec, they are designed to run without overflow tank.

Is a OEM radiator combined with the SPAL fan and silicone hoses also good enough to remove the coolant overflow? Thanks!

[@Powerbrickperformance]

@@Sietse-kc7bn it’s an improvement for sure, but it also depends on your climate. If you’re in northern Europe, yes, as temperatures do not exceed 30 degrees C, but if you’re driving slow traffic all day in 35 degrees C+, you wouldn’t get away with that setup

[@Sietse-kc7bn]

Thanks! I am from The Netherlands so I will give it a try! 🙏🏻
