So I got a new HP carb. Put it on and it starts up fine and idles and warms up and even made it a bit quieter, but when I got to give it any gas it just wants to bog and die. Starts up just the same afterwards. So I took jet out of my speed carb and my nt carb that both turned out to be the same ones but were slightly bigger jet than the HP carb. Think they were bout a 69-70 and the HP carb is a 71. Regardless of which jet I put on , they all perform the same. Idles just perfectly. Rev up engine great. Maybe the NT and speed carb jets sounded a bit better but achieved nothing different. So with all the blah blah I just told you, which way would you veer towards? Bigger jetting or smaller? I'm in Portland Oregon and I,think,I'm 0-100 ft above sea level no matter where I ride. Unless I,hit the hilly parts of town. Hope someone can give me some insight. I really want to use the HP carb but havnt yet and I bought probably 3-4 months ago.
