99 WR400. My bike seemed to be running ok until all of a sudden it starts sputtering and stumbling. I pulled the carb off and am checking and cleaning everything and while im at it would like to do the de octopus mod. I have done search after search about how to do it and come up with nothing. The only thing I find is people saying that they have done it but nothing on how to actually do it. I guess this is a little old school mod but can someone point me in the right direction please?
