Got a 49cc kit (lacking any instructions-not surprised) today and just waiting for the sun to come up to go get the tools out! I am installing on a Wheeler mountain bike which i just purchased off of Craigs list. Hope this goes well, I would like to get another engine for my son if I am pleased with this one. Any leads to some kind of instructions would be greatly appreciated! I am mechanically inclined and being so I do like to ask questions. I am really looking forward to this new hobby.
