    Is there anything that can be done to the head to improve the performance of the motor? I've had a look through a few topics but can't see anything, just asking as my heads off to check the bore and piston and to get the plug hole helicoiled.

    Cheers

      Yeah. The head is where the majority of the power is made. So yes. you can have the head reworked to alter the squishband.

      Really you need to speak to a tuner to understand what it is you're after, where you want the power to be made and what ignition setup you're running.

        Many thanks, do you know anyone reliable and proven I could contact?

        Got a DEP system and Zeel CDI, only looking for it to pull a bit harder not rev higher, make it more usable on the road.

        Cheers

          @Bluestoesonnose You can get the engine ported and tuned to make more power in the mid range, rather than peak power.

          Again, speaking to a tuner will be able to highlight what needs to be done.

          I don't know if he's still knocking about, but Mick Abbey might be able to help.

          When I spoke to him last, he provided free consultation, then I sent the barrel, powervalve and head off to him to work his magic. But he said it would be pointless without an aftermarket ignition system.
