Re: My experience installing a ZB 80CC Bicycle engine kit from E-Bay
For a little more boost you can use one of the 100:1 oils instead of the typical synthetic 2 cycle oil. It gave me a good boost and virtually eliminated all the smoke in the exhaust. I use the opti-2 oil. The manufactured said it could be used at 100:1 for break in but I wasn't quite brave enough to try that.
