Does anyone know the exact size of the 2 small screws that fasten to diamond shaped cover for the fuel lever/switch? 
Mine are worn and I would like to replace them with alan head screws. 
			
			
			
				I believe they are m3.  I switched over to allen and accidentally over torqued them and actually stripped the aluminum threads. I went back to philips and did not have any issues as long as I used a #1 philips 
Just be careful!
			
			
			
				he petcock rebuild kit I bought came with 2new allen head screws, look like m3 if I measure them
			
			
			
				Thank you! I took your advice and ordered new philips head screws direct from yamaha for  a couple of bucks. 
			
			
			
				No problem!
