Re: Low gas mileage!
The valve, petcock, that comes with the peanut kit tank is a metric thread. The link you posted is for an SAE 1/8" pipe thread. They're not compatible. The kit valve is not a pipe (tapered) thread but a machine thread that relys on a gasket to seal. With that being said I will say that I ran a 1/8" pipe tap into the threads on a tank and successfully installed an 1/8" petcock. Maybe I got lucky so I wouldn't suggest you try it unless you want to take a chance. Dax and Sick Bike Parts carries replacement petcocks with the proper thread and gasket.
