no it don't bother me give me a chance to see what went wrong and why by the end of the second year I had engines lasting half a season , I learned how to do allot of stuff I was changing cam profiles larger valves different flywheels making custom coil brackets im just jumping in with both feet and using a motor no one really uses for performance it is the onan 20.5 vtwin they pull like a bear just not allot if any performance parts for it , it will be a long road of research comparing its internal parts with other manufactures , for example the Honda motors part will fit and run well in clone engines .. the motor has one carb I would like to find or fab up a sheet metal intake for dual carbs or find what other carbs that breath better would fit on the onan intake,, usually on average a race will last 10 min but its usually at wide open ungoverned,, I did run a two stroke 440 snowmobile engine in one race and it was just unbeatable I melted the beads out of the rear tires and was trapped at 68 mph out of a turn in stat line Illinois but I was black flagged due to the oil the exhaust puts out from other drivers I probably could have remedied that but that was the last race I did
