I'm not sure if you know the area,but around Willow Grove there's three places I've heard Tricked out customs (or somthin like that),Fast by Ferracci,and The Cycle stop. Go to FbF or TOC for tuning or perf. and go to Cycle stop for gen. repairs...There's also Montgomeryville Cycle.This is a dealer you'd go to for gen. repairs and they'd refer you to perf. shop too.I've bought all my bikes there and have had good experiences w/them...I've never had to use anyone's repair services,though,so I couldn't say how any are as far as that goes,but I've heard those are some good ones.
