The Hodaka Club Forum

Stumbled across this on youtube.

Shows the use of a "solid" adjustable type hone for honing small cylinders.

This video is more than honing for finish work. It's really re-sizing with a hone. I've done it more or less like this. Seem to be able to keep taper and roundness to maybe half a thou. I prefer to do my own work if I think I can.
I make mistakes but like to learn how it's done. Usually get it right the second or third time.


Is there some information about the similarity of this "Indian" engine from around 1974 and the Hodaka cylinders from the same era?

If link does not work, search ' honing me 100 ' on youtube and it will pop up.

Depending on your intended question, here are my thoughts:

Are the Indian and Hodaka similar enough to use the same technique? Yes.

Should you use a hone to increase displacement to one or two steps above standard? No.

Is it practical to buy the proper tool to do this at home? No. Not unless you intend to do it frequently.

Is it possible to use a hone to remove taper, hourglass shape, or any other out of true condition? No, not really. It depends on the degree of error and quality of the hone, but trueing a bore is not what a hone is intended to do.

Generally, the type of hone used for this video is expensive compared to having the job done professionally. This hone shown, for example, retails for $277+.

For that kind of money, you can have the cylinder professionally set up or even silicon nickel carbide coated and diamond honed.

Even with a proper hone, the shoes do float on the work. That is, they are spring loaded. If your cylinder is tapered or hourglassed, a hone will usually tend to follow that contour rather than correct it. The guy in the video is also running the shoes part way out of the bore, which is bad practice. Not that many an engine hasn't been "bored out" using a hone, but I would not do it, and would never pay someone else to do it.
