Anybody get an extra coolhead forsale?

I have a Paul Turner cool head????

That looks like one, does it have a number stamped on the dome some place?

Is there no differance with this 1 and 1 that speed makes?

You might find a few minor differences in appearance or physical size but the function will be the same.

Should be a number stamped on the dome some place like 47 or 49 this would indicate the size of the dome.

Yes they do, i have
49cc
50cc
51cc
52cc

the only difference i can see between the turner and speedchaser is the warm feed for the carb on the turner but you don't need it away????

Correct, most people swap out to the 39mm PWK carb so the water passage to the carb is eliminated and that extra port is not required on the head, we decided not to offer it on the speecdchaser version of the head because of the extra cost involved and it just does not make any sense to have it when 9 out of 10 owners just plug it, on the speedchaser head if someone wanted to still run the stock carb and wanted the carb heat feature you could easily drill and tap a 1/8" pipe thread in the head and get a pipe fitting to screw in.

davidafco would want the 49cc dome for his hoserized Engine, surprised you don't also have some 47cc domes race gas hard to come by in your area of the world?

does the Paul Turner head use a Oring for the head gasket?

No O ring you use the OEM gasket.....we can get race gas over here but our pump gas is RON98 min can get 105 at shell garages only problem it's over £12 a gallon

Far as I know the Pro Design Cool Head was the only Pilot after market head that used the O rings over a head gasket.
