Schwinn Delmar cruiser engine options?
So I just got a new Schwinn Delmar Cruiser from Walmart and i have been looking at engine options and was wondering what engines or sizes you guy would recommend. i have experience in mechanics of 2 strokes from RC cars days tuning and that shouldn't be hard for me. But the only engine options that I have seen are the china engine something or other and they all look the same to me at least. Do some kits have a centrifagul clutch or would you recommend the manual clutch? Thanks for any input and suggestions on this.
