    i havent done that yet the plug chop i need to clean around the plug. i have sand all around it im going to lower the needle tomorro. im running a 146 main jet it idles fine , and drives fine but when u give it full trottle it quits pulling hard. but if i give it 3/4th throttle or alittle more its keeps pulling i want to run it again something so i can see if its faster. but it seem like i lost alot of wheelie power.
