F2 Thrust Pipe vs. CDH66

[phvega76]

Hello, I am on my very first bike build. I have a Zeda80 triple 40 engine kit with High Compression Head, G2 Reed valve, OKO 21mm carb and a lightly ported cylinder. I currently have a F2 thrust Pipe from BBR which has a small expansion chamber. Would a bigger expansion chamber benefit my set up?

A bigger expansion pipe will definately help. Mz65 is probably the best but hard to find. If your able to weld a scooter expansion pipe works well or a dirt bike pipe also works well. The cdh66 is probably an upgrade from your thrust pipe

Can confirm a scooter one works very well!
