Review on Dolphin1986 Cylinder Machined Motorized Bicycle by Justin Rasmussen

Each of these heads and pistons is a CDH product. The longest I had lasted a week or so. , all rubbish. The last two DID NOT EVEN WORK. BOTH compression Compression refused to compensate. Before I say anything, YES I mix the oil well, YES I make sure nothing goes in and doesn't get into the flask. NO, I do NOT use any extras, ONLY what comes with the kit. Why are they such a slob? I have spent a lot on it and I am concerned about the quality of your products.
