I have a question . I was reading the new Motorcross Action last night. It said Ferry runs a Highly modified Production carburator. It also says most notibly that there is no Throttle position Sensor . And The bike starts on the first kick everytime and never needs the hot start button. How come we cant do the same .Why would I have to do the BK mod if that is the case . Any Help would be great . Thanks for your time . I couldnt get any good answers at DRN . Althought I screwed up and wrote accelerator pump instead of TPS.
