Re: bbenxe's B50T flat/street tracker

Thanks Ben, The slide in my pwk is also unmarked so perhaps there is only that slide. The most significant differences between the N427-46 & the N427-48 needles is the diameter which means that the needle jet also has to be different. The length is different too, - but perhaps that is depending on t...

That was exactly my concern with the regulator connected on the battery side of the ignition switch.
