chi lpg spark plugs

Got me some chi heads, what spark plug do i need to suit lpg, they look like they need a long reach plug? Does any one know if there are bolt perfect fit extractors for these heads? I was thinking of doing my own pipes and selling them online to suit chi heads.

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.

Re: chi lpg spark plugs

If you bought them recently? Off the shelf pipes should fit. I run pacemaker 4070's on my 218cc one but 4075's would have been better

Hof 351 : You measure and figure out where centre is between the carb studs/bolt holes. Then measure around 15-20mm down. Drill a hole and tap it with the correct thread to suit the port your trying to screw in.
