Beta Techno 250 1996 Water Pump Issues and a clutch Question

[cello]

Got a couple more questions as the bike takes shape, the cooling fan or rather the thermostat/sensor any ideas what the resistence readings should be or how long it would need to idle for before the fan kicks in?

 

My sensor was reading 8 MegOhm reducing to 4 MegOhm after about 10 minutes and the water hoses and rad were all hot but no fan , I know the fan works as I have shorted the sensor and it ran fine.

 

The other issue looks like the clutch plates have swelled due to the water in the oil , any ideas what thickness a new friction plate should be and if i could take a grinder/file to them to reduce them somewhat?

The bike starts but clutch drag means I cannot change gear when the engine is running so need to rectify this before I can try the Techno out anywhere apart from my back garden , TIA

Hello you can  test the thermo sensor in a pan of  boiled water and use a multimeter set to continuity on the terminals. As regards the clutch if you are on a budget you could just use the bike and see how it goes, and slip the clutch a lot to encourage them to comply but personally I would bin them and fit new plates.
