They must be good then. They are three times the price of the NGK brand.

Below is my stock one I bought new in 77 and one which I built to what I actually wanted in 77.

Nice bikes....

As stated, leave it be, it's beautiful as is.

Or go hog wild. :woohoo:

Can't believe I'm gonna say this as I'm one of the biggest fans of a header, pods and stripping off the turn signals, center stand, pass bar etc to save weight and clean it up but..... I wouldn't touch it either.

Seems like the horse is out of the barn since the Kerker has been purchased by the boy. My suggestion beyond this point is to keep the airbox unless you enjoy tinkering with jetting; pods upsets the carb jetting needs way more than a header does. And if you go with pods regardless the real deal K&N brand are superior to the generic look-alikes on the market.

While the carbs are off is a good time to replace the rubber boots attached to the head. It's critical that these parts seal well and 40 year old rubber tends to be unreliable.

Good luck with your project.
