Newbie here. My guy reciently got a beach cruiser with a RAW 80cc. Pre-assembled. He LOVES it, WHEN it runs! LOTS a problems! Who knew there is SO much to know about these bikes. Between us we know NOTHING, except for some tips and info I've already picked up from this forum. Can't tell you all how GRATEFUL I am to have found you all!!! We had no idea WHERE to turn for answers to the problems . . . and then VIOLA!, you "magically" appeared while I was searching (& searching & searching) just for a new spark plug. All the time and effort you all put into this is MUCH APPRECIATED by myself, my guy, and I'm sure MANY others who, like us, are trying to get the hang of this motorized bicycle owner/operator "stuff"! GUARANTEED I'll be around LEARNING from ALL of you!
