I am looking at putting on new pipes, a/c, and re-jet the carb. Looking at the Arlen Ness Big Sucker A/C, and I see that for about $20 more, I can get a chrome backing plate.
Anyone know what this does for the A/C? Don't really mind spending a little extra if I actually get something out of it - but as far as I can see the backing plate isn't visible anyway, so guessing that this would have something to do with performance, but what??
