I have a 1994 Laverda 668 that wont start when hot! I need to let it cool down before it will start again. Could it be a temperature sender or oil temperature sensor? can anybody give me any hints?
Many thanks, Simon.

One possible cause is that you dont have the correct clearances for the valves, if there is not enough clearance, once the engine gets hot and the valve expand, they can hold the valves open (usualy the exhaust valve)... this would cause low compression when hot making it hard to start.
hope it helps

1994 tercel overheated now wont start


I answered this with a lengthy explanation.. about blowing your head gasket do not run a car when it over heats it will cost you a engine.. wait until it cools down to add water and most likely you need a new thermostat or you already have a blown head gasket .. this is much cheaper then an engine do not drive car when HOT.
