I realize it isn't a bonafied name brand phbg, but its a staright clone for less than half the price including and ar filter and a throttle cable. I don't know what to tell you but my arreche sucks nuts. The bike it came to me on had a questionable history, i.e. it was all kinds of fucked up, and the areche constantly pukes gas, and the del 14 I had before didn't, so I donno, maybe this one is just old.
