NE5 Carb Problems

[buddyearl]

I have a NE5. I wanted to increase speed so I enlarged the restrictor plate.
The bike has slow acceleration and is doggy. It does get up to speed but when throttled it dogs out. I have 35 pilot and 80 main jets. Idle mixture is completely closed and idle speed is several turns out. Can someone give me advice on how to increase engine performance?

This happened to me when I opened the restrictor plate as well. I would take a file and file the edges so they bevel in the direction of the fuel flow. I found that the sharp edge on the widened restrictor plate opening was causing a bit of turbulence in the fluid stream. I hope that makes sense.

Regards,

Matthew

What size pilot and main jets are your using on your NE5?

What groove is the clip in on the needle? A #82 main jet and the clip in the second groove from the top is a very good place to start. Many use these settings with good success. With a #80 jet you may be running lean.
