I got a set of new intake rubbers a year ago.
Now a few months back I was installing a Raptor 660 carb to my XT, and I noticed that this little tube had a tiny hole in the rubber surrounding it. After a closer inspection I found out that the alloy (in which the bronze tube is fitted) has a little crack and is sucking air.
I ended up cutting off the bronze pipe, drilling a 5mm hole (removing the bronze tube completely) and threading it for a 6mm screw. To seal the crack I applied quite a bit of Loctite to the screw's threads and also some heat resistant silicone to the top of the screw (covered the screw head completely), to make sure it doesn't suck air once cured.
So... Should I throw away my 1-year old rubbers with a makeshift sealed crack, and get a set of new ones? :confused1: this vacuum storage sounds weird... It stores the vacuum, but it also will lag to make vacuum for the carb when you quickly twist the throttle: it will have to "increase" the vacuum in the tube before "increasing" it in the carb, thus delaying the lift of the vacuum slide.
Also, in my Raptor 660 carb there is a vacuum slide in the left carb, but there's no vacuum slide on the original YDIS carb.
