well for starters u got front drum brakes when u increase the power u need better brakes to stop then u need to grind down the mounts exactly till the engine fits but the front and back wheel have to stay inline, then u need to get a typh 125 loom which seem to be pretty rare now and then use both the zip loom and typh loom its pretty long do a search i know minor confusion has explained it a few times and dont forget if not done properly it can be dangerous!
