I have a 2001 Pacemaker 2. The bike was still in a box when I got it 3 weeks ago so the carb must be standred issue with this year wc1 motor (I'm guessing) it has it's own pepcock, if that helps. Can't find a model or brand on it. I have it running and it idles and runs good but when I get it reved up it goes flat at about 2/3 throttle. Is this a main jet issue? If so does any one know where to get parts for this carb? I pulled the main jet,soaked and cleaned it but no change. Any advice or knowladge would sure help. Thanks in advance!
