Hello everyone. I just picked up a kart that has a fresh Dover Harbor Freight Blue Clone Stage 3 in it. Well, it was built in 2009, but has only been ran maybe once. Obviously, these are no longer being built or offered by Dover. I did get the dyno sheets with the motor. I called Dover and asked for any info on them and they said it may or may not have a cam in it. I'm not sure what the options were back then for upgrades or what came standard on a Stage 3. I'm not sure if it has a stock carb or if the Holy Moses carb was an option back then. I did notice the valve cover has a vertical crease in it between the valves. The motor cost $700 and the spec sheet says it has #38 jet in the carb and it should run between 5,200-5,600rpms. Not sure about the valve train. The max hp was 10.71 and torque was 14.38. Dover said it may not be as competitive as the newer clones due to the advancements in the 4 years since its been built, which I totally understand. This is going to be my 8 year old son's first year in Junior 1 moving up from the Kid Kart class last year. I'm just trying to get him some seat time this year with more power. I know regardless, this motor will have plenty more power than our completely stock motor last year we ran. Lol. Thanks for any info!
