WE HAVE THE BEST AND THE MOST MOTORIZED BICYCLES IN TAMPA… F.A.Q.=Is there a “break” in period for a Motorized Bicylce Engine? YES! Taking GREAT CARE throughout the initial first 2 (full) gallons of premixed gas is essential! 1. Use a fuel mixture of 16 : 1 ( Gas to Oil ) (8oz to 1gal)with the use of Synthetic 2 stroke motorcycle oil and Octane 89 or above gas. This fuel ratio is recommended for the first 2 full gas tanks. Once broken in, you can drop the ratio to 20 : 1 ( Gas to Oil ) (6.4oz to 1gal). 2. Do not ride the motor for more than 10 – 15 minutes at a time till its broken-in. 3. Variable speeds are recommended and do help with a good break in such as running the motor slowly, then revving high, then going slow again. However do not run the motor at full throttle for more than 15 – 25 seconds at most. This is an essential consideration and critical to the proper operation of the engine during break-in. Following proper break-in instructions means that pistons and rings will not seize. Proper break in followed by routine maintenance will allow your motorized bicycle to take you thousands of miles.
