I'm from the northern suburbs of Philadelphia. I currently have two rides, a Look AL384 road bike which I ride most frequently. I also have a 20" BMX bike PK Ripper Team Edition. I plan to put a 4 stroke kit on the PK Ripper. I've already scoured the forums here and have found so much useful info. I was so happy to see there was such a community surrounding this subject. My one friend put a 2 stroke on his bike and after 1 ride.. I was hooked.
