That Malossi is a nice kit but too much dough... Before I spent any money I would put the Bing back on with proper jet and atomizer and TEMP GAUGE trail-tech... and slowly break it in a while...they do run hotter when they are new...I like to heat cycle it a dozen times or so. When it starts getting weak and boggy the temp is usually 250 - 300 + You would be surprised just how good that Malossi kit will run with a 14/15 Bing carb and a temp gauge
