In the beginning….

I boosted this Yamaha YZ250F up to a YZ290F with a 6mm big bore kit from Athena!! Monster torque doesn’t even come close to describing the dirt slingin, wheel standin, crazy power this little giant puts down now!! Third gear wheelies with just the flick of a wrist!!

I still recall the first time I met a Genesis motor back in the 90’s. Those five valve configurations really blew me away! The general idea is less mass with equal or more flow equals higher revving and performing engines! Four stroke design and technology has increased at an amazing rate in the last several years. The intense amount of horsepower while maintaining calm, controllable power from 2000 RPM’s and up has made these bikes more fun, frantic and fierce all at the same time. I love my job!!

Ethanol Shmethanol!!

DO NOT ADJUST YOUR TELEVISION SET!! The beautiful green tint highlighting these carburetor parts is due to the ethanol content in that stuff they call fuel which we fork over an exorbitant amount of clams to purchase!! The ethanol acts like a sponge, drawing water from the atmosphere and causing it to accumulate in the relatively small capacity float bowl to the point that ALGAE grows in GASOLINE!!! And then it wreaks this kind of havoc upon our motorcycles and power equipment. It’s just the governments way of helping small businesses turn a profit…

Fuel is supposed to flow through the slotted jet in the center of the photo... But the algae has it completely blocked.
