i just fnished doing a top end rebuild (bored 20 over, wiesco pistons) now it fouls plugs like crazy!! i normaly run 32:1 yamalube... the first tank after re build i ran 24:1,and it seemed fine, now i'm using 32:1 on my second tank and it fouls all the time... i never changed jets (320 main 25 pilot) i cleaned the carbs before i put it back together. Do i need to re jet just for going 20 over...also it seems that when i'm in 6th gear it seems to rev higher and pull harder when i'm not quite full throttle.. if i pin it, it seems to make a deep slower revving noise.. not a bog or anything just seems to loose rpm. when i'm driving it hard the plugs look good nice dark brown colour... its only when i go slow that it does this.. i know banshee's arent meant to be driven slow, but it never did this before so something is up. Thx for all u'r help guys..
ps. my mods are t6's, with toomey 2:1 intake, boyesen reeds boost bottle 4* timing key
