i just installed a 28mm pwk carb on my blaster. being confident in myself i loaded it up and drive two hours to my fav. riding spot. got there had to choke it to get it to start. once started it was good.....until i got to third gear and gave her hell, fell flat on her face. so i took the breather box top off and it helped a little. just wondering if my stock pipes cant handle the extra flow.
