Been using a B6HS spark plug on a V1 with a 47mm BRN head. Can it use an ES length spark plug or will it be too long and damage the head?

Easy way to tell is to put an ES in the head, turn the flywheel over by hand gently and see if it hits it. If it doesn't you're good.

I am using a hs on my brn head. I did not check to see how far the plug goes in but it definitely is not hitting the piston so it is not too long.

Did you mean to say ES?
No, I said hs, because the plug in my garelli with a brn head is a b7hs.
I have never run an ES in my bike.

Well he's already running an HS so that wasn't really the debate lol. Saying it's not too long is obvious since it's the short one.
But yeah removing the head and screwing in an es and looking at it is the easiest way to tell for certain
Thank you for the input. but, in lew of taking the engine apart is there any way to tell if its safe.
Is there anyone that has run an ES on a 47mm BRN super street squash head on a polini.
Any help would be apreciare.
Thank you in advance.
Use your head . The one above your shoulders .
Simply remove the spark plug and measure the depth of the threads in the motor head .
That's the length of spark plug thread that should be used .

gee, tried that. It won't fit in there the hole is too small; 14mm I think. Not sure?
You have nothing that fit's in that hole ?
Try a tooth pick .
I'll make a tool out of a bent wire or just run the 12mm thread length espese for the stock head. Thank you for you advise; I just thought that someone might have run a plug with a 19mm thread before.
Thanks again.
