    Raptor 660 Modifications
    02 660 with proflow adaptor and foam UNI. Big Gun slip on. Mains are at 175_180 clip on 4th, Ran great. Then when from a big gun slip on to the full Yoshi and was lean mid range. So clip was moved to richest position. Runs good but feel like it's a little too much fuel for my mods. Anyone else...
