i have a 94 blaster with a 240 big bore, 34 mm mikuni carb and a uni air filter. this should make it sh*t and git pretty good right? to me it seems kind of doggish and it is burning a lot of fuel and it is not getting much acceleration from first to third and not much top speed when im in 6th it seems to excelarte better with half throttle than when i hold it wide open. any ideas
