Re: chi lpg spark plugs
Wander into Repco telling them you normally run a NGK BCP5ES and you want a plug to suit gas. They'll point you in the right direction.
Which version of the heads? 3V 185, 3V 218, 2V 190 or the new 4v?
John makes the heads to order. He can set the 3V types up to fit off the shelf pipes without an issue. All you have to do is specify what you want and are running. Even without John doing anything to the head all you need to do is bend the pipes down 10mm. I'm almost 100% sure John sorted this. There was a change to the mating face of the pipes around 12mths ago or more.
The 2V and 4V versions will fit off the shelf pipes without an issue.
