Hello i am grease monkey! Im new to the forum and have a few questions. I have had an engine installed on my bike for about two years now and its time for a bit of a rebuild. Im looking to order some parts like gaskets, a better chain tensioner, etc. I have been looking at bike berry, sick bike parts and gas bike.net are these good places to get parts of good quality and good prices? or are there better places to shop?? I am also curious what is the difference between 410 chain and 415 chain? Are they interchangeable? Forgive me if i am missing something obvious here. Thank you in advance for your help!
