MZ 65 and Bertha pipes tested on Super Stocker engines

[Street Ryderz]

Here's the Burtha pipe again on a stocker engine and the pipe still in it's stock form.This pipe has great potentail being a true 2 stage pipe it actually hits softly early and carries over a broader range,yes it's loud but it does truly let the engine breath.

This is the MZ 65 on the same stocker as previous video just dialed in a bit better.I really did this video to prove that even a properly setup stocker could climb and accelerate up a steep grade.it's the same hill I ran the 48-50cc up,the pipe allows good flow to accelerate and pull pretty hard again I don't find the hit very hard but it's noticable, it didn't even get on the pipe here it was about too as It started to level out but I lifted because my point IMO anyway was made LOL.So yes as a bolt on for stock to mild engines this pipe is pretty good.Though I must say I'm suprised because they don't do a very good job of putting it together and the chamber really is just an enlarged banana with an extended divergent and actual header/stinger.

Here's one just riding for fun my neighbour,son and myself.Yeah it's much more fun to ride just to ride and not be testing or tuning.
