Are those centre plug heads you occasionally see on Yahoo Japan real Honda/HRC or are they home made ones? _________________ Please do not PM me technical questions, if you can't find it on the Forum start a thread
I'm not going to cut one of my HRC ones in half I can promise you!
Thats infact the reason I cut them in half. I wanted to know if you could mod stock ones to HRC spec. Answer, no. Not unless you do a lot of welding. _________________ If I have to take the carbs off once more...
Ah, the question was not "is the head in the pic HRC .......", the question was "are the centre plug heads you see on Yahoo Japan HRC or home made"?
I can see the head in the pic is a normal one.
The question now as I guess from your answer there are HRC true centre plug heads is "did HRC make them from normal heads and therefore can someone else?" _________________ Please do not PM me technical questions, if you can't find it on the Forum start a thread
HRC did make heads but they did not use the same casting as an OE head (this was what I was trying to find out).
You could make one using a OE head but it would involve welding a rather large section back into a stock head then having it remechined. _________________ If I have to take the carbs off once more...
As you can see the OE spark plug location is still there but never mechined.
However you can not relocate the spark plug as HRC have done in a stock cylinder head as there is no material there! (see first pictures). Cunning stunts!
A set of these have found their way onto my R6K _________________ If I have to take the carbs off once more...
