<![CDATA[Cylinder head]]>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

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.

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

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.
