| Fuel Tank breather valve info please...
My baby seem to be hesitating on accleration lately....
not a good opening line for a song but, it is very noticeable on some throttle openings. I have noticed at times the gas is under quite some pressure on opening the filler cap - If my reasoning is correct the little alloy breather valve in the vent hose allows the pressure to build to a set value - yes ???
Well, my bike seems to run a bit better without the valve in place. I also tried blowing down the darn thing and couldnt blow through it. I'll try with a hand pump sometime but does anyone know what the open value should be?
Also is the valve just to prevent the petrol gassing off continuously or does it have another function??
