To start, I just started riding two summers ago, so I am new to motorcycles. I have learned a lot from reading posts on this site. It seems there is always someone willing to help with a problem. THANKS! I recently removed/disassembled the carb and cleaned it all up. The bike ran ok last summer, but after sitting for a few months it was difficult to start and it ran terrible after it did start. It wanted to die when you would snap the throttle while in neutral. The mods on the bike last summer were airbox lid removed, exhaust unplugged, and throttle stop shaved. While I had the carb off, I did the "Taffy Mod" and disconnected the Grey Wire. The bike still wants to die when snapping the throttle while in neutral, and now after riding up and down the street, it does die when I pull up to the house after shifting down to first gear and pulling in on the clutch lever. It is also spitting/popping out the pipe after down shifting. Unfortunately I have to have the plug in while testing on the streets near the house. I am pretty sure it is all a jetting thing now, but I wanted to get some ideas from anyone willing to help on this site. I did not change the jetting from last summer. Jetting is as follows: Main Jet = 158 Pilot Jet = 45 Pilot Screw = 2 turns out Starter Jet = 60 Main Air Jet = 200 Pilot Air Jet-1 = 75 Pilot Air Jet-2 = 90 Jet Needle = Clip on groove #2 (second position from top) I live near Boulder Colorado. My riding is between 6 and 12k elevation.
