Has anyone used the aluminum head and big bore cylinder from Trinity and what percent increase does it buy over a Hetrick port, carb upgrade and clutch mod. Also the CDI box and digital electronic ignition what does that get as as percent increase. My quad is really fast and gets most all the hole shots.

 

Stay with your Hetrick machine. When you start getting cylinders from one and pipes from another, it gets hard for them or me to help you because of the mix match of parts. Rich has more than likely set up the parts he gave you to work best together. You start putting kinks in it and you will be asking for headaches.
